Adds texture to the hair
4 months ago
[This review was collected as part of a promotion.] I received the Redken Acidic Grow Full System Instant Densifying Spray as a courtesy to test and review. This spray has the same Lemonchello scent as the rest of the system. The bottle has a nice spray function with a locking and unlocking tab which is great for travel. This Densifying spray feels and acts to me like a sea salt spray. While wet, this product is slightly tacky and once dried, feels like the hair has a gritty almost texture to it. This threw me off a bit as the Redken products are usually soft and clean feeling to me. I am excited to see the after affects after use over time.

Too soon to know for sure the effects, will update
4 months ago
[This review was collected as part of a promotion.] So this Redken four step system for thin or flat hair is PERFECT for me. Not only is my hair thin and flat, it is also damaged from tons of dye and a little bleaching in the last year. It’s been rough on my hair for sure.
So far, the main thing I have noticed is how GORGEOUS my hair looks after using this system and then blow drying and styling it! I will also update the review with pics of my hair when I do that as well.
I believe my hair has become stronger, but as I said, it’s still too soon to tell how well it is working. But so far, I love the ease of use of the system and the ingredients! Azelaic acid in haircare?! Yes, please!

Lightweight Volume and Instant Fuller Look. #free
5 months ago
[This review was collected as part of a promotion.] I received for free Redken Acidic Grow Full System Instant Densifying Spray, and it made a noticeable difference in how my hair looks and feels. In terms of density, my hair appears fuller right after styling, especially at the roots. The spray dries quickly and doesn’t leave any sticky or wet residue, which I really appreciate. My overall appearance looks more polished and healthy, with less flatness. It adds visible volume without making hair stiff or crunchy. Most importantly, it feels very lightweight, so my hair still moves naturally. This spray is a great option for fine or thinning hair that needs a boost without extra weight.

Instant lift at the roots
3 months ago
[This review was collected as part of a promotion.] I received this product for free for testing purposes.
This spray is amazing if you want immediate results. Right after using it, my hair looks noticeably fuller and has more body, especially at the roots. The best part is that it doesn’t make my hair feel stiff, crunchy or sticky like a lot of volumizing products do. My hair still feels soft and natural, just with more volume. The scent is not overwhelming which I appreciate.
I like using it before blow-drying, but even on dry hair it gives a nice boost. It’s perfect for those days when your hair just feels flat and needs a quick fix.
It doesn’t leave a buildup, doesn’t flake and is easy to wash off.

My favorite acidic grow product
3 months ago
[This review was collected as part of a promotion.] Redken's Acidic Grow densifying spray is my favorite product from this line. The locking mechanism on the bottle is useful for making sure it doesn't spray when you're traveling and I don't think I've ever seen another hair product with a little toggle to lock the lever, so I thought that was pretty cool. I feel like this product, which happens to be step 4, is the only one that makes a noticeable difference in my hair. I could do without the shampoo, conditioner, and serum. In fact, I've used this densifying spray after using regular shampoo instead of the rest of the Acidic Grow line and still had good results.

Kinda slimy
3 months ago
[This review was collected as part of a promotion.] I received this product for free in exchange for my honest review and opinion. Nice size bottle with a closing mechanism so it won’t spray out into your shower bag at college or when going on vacation. It dries super fast but the consistency was kind of slimy. It has a pleasant clean scent. The instructions weren’t very clear but I assumed that you spray it on your roots and rub in the help strengthen your hair and promote growth. I didn’t see any visible results after two weeks of use every single day. It left my hair a little crunchy.. my hair density didn’t seem to change. Great value but wouldn’t purchase.

Instant volume + heat protection
4 months ago
[This review was collected as part of a promotion.] Redken densifying Spray is one of my favorite styling steps because it gives instant body and fullness without making the hair feel sticky, stiff or heavy. The texture is super lightweight (almost like a fine mist), and it leaves the hair soft and touchable- not crunchy.
It’s also really versatile: you can use it before blow drying for root lift, or even on damp hair when you want extra volume without making adding another product. I love that included heat protection too, so it’s perfect if you style your hair often.
Overall, it makes the hair looks fuller thicker, feel healthier and stay light and bouncy.

Length and volume
2 months ago
[This review was collected as part of a promotion.] The acidic grow full product line has really helped grow my hair along with making more volume for me. I typically have very thin hair and it is very hard to give it any movement. While using instant densifying spray I was able to achieve a little bit more length and a little bit more volume. Simple to use after the shower and doesn't dry out my scalp like some products. Spray nozzle held up well, I ended up wiping it off after use but it only took me a second to make sure there was no buildup on the nozzle. A nice fine mist helps to make even distribution of the product in my hair. Definitely a good system.

Love it! Gives nice complete feel and look
5 months ago
[This review was collected as part of a promotion.] Disclaimer: I have received this Redken Acidic Grow Full System Instant Densifying Spray absolutely free in exchange for my honest review.
I was pleasantly surprised how great this densifying spray is. It gives you a really nice lift. I usually use this as the last step of my Redken routine. After shampooing and condition i get the serum worked in and then go spray happe all over my hair. It makes them feel really nice and full as well as smell nice. Unfortunately it doesnt smell as delicious as the shampoo but it will do! Love it! Just makes sure to spray not to close to your head though otherwise your hair will just feel crusty. Put some distance between your hair and spray.

Redkin densifying spray
4 months ago
[This review was collected as part of a promotion.] I really liked this spay and think ot worked well and added extra volume to my hair! The volume held through out the day. My hair felt soft and manageable. Drying time was average to normal drying time of my hair since I applied it to my wet hair. I feel this is very great quality and and sprayed evenly where I wanted it to. The direct nozzle makes it easy to apply exactly where you want it. I am very satisfied with this product.

Works well, pair this with the hair growth system
4 months ago
[This review was collected as part of a promotion.] First I want to thank Influenster and Redken for this complimentary hair system for my honest review.
This bottle comes in a plastic bottle with a squeeze handle.
This product does hold your hair and makes it crunchy and stiff.
For better use I spray it closer to my scalp and work it into the scalp and top of the head only while my hair is wet.
It does not have a scent, at least not to me.
This works well as far as I can tell. Pair it with the rest of the hair system.
It does not dry out my scalp or cause any irritation.
I give this 5 out 5 stars.
I recommend this product.

Adds volume, but dirty hair feel
3 months ago
[This review was collected as part of a promotion.] I was very curious about this product, but was interested to know that my hair felt very sticky when using it following the shampoo and conditioner in the system it almost felt like I put in a texturizing spray at my roots. It made it very hard for me to run my fingers through my hair and felt dirty at the end of the day as if I had to wash it even though I just washed it with the full system. I’m not sure if I would label it as an identifying spray, but it definitely feels more like a root lifting spray. I thought by the packaging it was meant to be more of a hair growth product but in this case it’s just to make the hair look fuller which it does, but the hair feel is a little uncomfortable.

Consumer Care Center
Hi there! Thank you for reaching out about our Acidic Grow Full System Instant Densifying Spray. We appreciate your observation regarding the product's function. You are correct that this is a styling treatment designed for instant volume and fiber expansion, rather than a long-term hair growth product. It acts similarly to a root lifter by coating each strand to create the appearance of thicker, fuller hair immediately. The "sticky" or "texturized" feel you described can sometimes occur if the product is concentrated in one area or if too much is applied to dry hair. For the most comfortable results, we recommend:
Applying to damp hair only.
Focusing on the roots and combing through to ensure even distribution.
Using a blow-dryer to help "set" the densifying agents, which typically removes that tacky sensation and leaves the hair feeling fuller but manageable.
Your feedback regarding the packaging and "hair feel" is incredibly valuable to our development team as we strive to balance high-performance results with a professional finish.

Noticeable Fullness
5 months ago
[This review was collected as part of a promotion.] As someone who suffers from thinning hair that lacks volume this hair care system has been wonderful! Almost immediately I noticed more fullness in my hair and I love this densifying spray along side the other products in the system. I love that this doesn’t leave my hair feeling crunchy, sticky or heavy but it still gives me that lift that I need. I love that. It is actually helping. Strengthen my hair overtime not just masking how thin it is. The scent is pleasant I wouldn’t say it’s my favorite but that’s not very important to me as long as the product works. I will say it’s not overly strong or overpowering because I do tend to get migraines from heavy sense that is not the case with this.

This spray truly made my hair feel so full and thick I couldn’t actually believe it! The bottle is beautiful and sprays such a strong full mist it covers so much area on your head you need minimal product. The smell is amazing as well!

Fuller hair
4 months ago
[This review was collected as part of a promotion.] Redken densifying spray did tend to spray in a stream, it was harder to concentrate where I wanted to spray. It combed through nicely and did not leave my hair feeling sticky or weighed down. I like that it is a heat protectant as well. My hair does look and feel fuller since starting the system, I even notice it feels thicker when wet. My scalp did feel a little tender but adjusted after the first couple days. What I really noticed is that my hair is not as oily on the second day which is a major win as I tend to shower daily due to oily hair. All products have a lemon herbal scent.

We love hearing about that second-day hair win! To help with that 'stream' spray, try holding the bottle 10–12 inches away or rinsing the nozzle under warm water to ensure a fine, even mist. For more tips on maintaining that fresh, oil-free feeling, give our experts a call at 877-254-9949 (M-F 9:00 am – 5:00 pm ET). ✨

Instantly thickens hair!
5 months ago
[This review was collected as part of a promotion.] This is one of those products I didn’t realize I needed until I started using it consistently. The Instant Densifying Spray gives my hair that immediate fuller look without feeling sticky or stiff, which is huge for my fine/thinning hair days. I spray it at the roots and through the lengths before styling, and it instantly makes my hair look thicker and more alive, not weighed down. It also layers really well with heat styling and doesn’t leave that crunchy residue some volume sprays do. Keeps my scalp feeling clean and very easy to wash out at the end of the day. I don’t feel any residue left behind. The product thickens my hair to last all day and I work in a hospital so some days are more trying than others.

Nice product!
5 months ago
[This review was collected as part of a promotion.] I was excited and nervous to try this new Redken Acidic Grow Full System Instant Densifying Spray . I have natural, long, thin hair with oily roots and dry ends. In 90% when I try new sprays serums or other leave-in products- my roots look greasy and feel heavy!
I experienced bad hair loss recently - I need to help my hair.
I use this densifying spray after Shampoo, conditioner, serum from the same Redken System. I just spray it on my damp hair after serum and use hairdryer as usual.
Watch my video - this is the proof- how soft and light my oily roots feel after BOTH leave in products from this system. I’m impressed!!! Will continue to use this spray for my hair. Hope it’ll help with growing new beautiful hair.

Great densifying spray for thin or flat hair!
5 months ago
[This review was collected as part of a promotion.] The Redken Acid Grow Instant Densifying Spray is amazing!! I use the full system for thin or flat hair to add density and strength. The formula is pH balanced with azelaic acid and 5% densifying complex. The Redken Spray helps my scalp feel more balanced and hydrated. It also creates a fuller look by coating the strands and reducing breakage! I spray this when my hair is damp and onto my scalp, from at least six inches away. I don’t rinse it off and am able to style my hair as usual! I love how revitalized my hair looks and feels with the Acidic Grow Full system!

Liking the hair system

[This review was collected as part of a promotion.] I’m starting off by thanking #redken and #influenster for this hair system I’m so happy and excited to keep trying it and I’m really hoping it works, this densifying spray claims it strengthens thinning hair which I have and reduces breakage which I get occasional, and creates the appearance of fuller looking hair, and I been using the products how it says and twice a week for 3 weeks already, even though I can’t see a huge difference I think my hair does look fuller when I brush and I apply this spray, I’m going to keep using it and I’m hoping it just works.

Great quick fix for adding volume
3 months ago
[This review was collected as part of a promotion.] This is a great quick fix for adding volume. It instantly makes my hair look fuller and thicker without feeling heavy or sticky, which I really like. It’s especially helpful on days when my hair looks flat.
The only downside is that the effect is temporary, and I wish it lasted longer throughout the day. Also, you have to be careful not to use too much or it can slightly with your hair down.
Overall, it’s a really good styling product if you want an instant boost in volume and thickness, not just a long-term solution for hair growth, in my experience.

Added volume to my hair ✨
5 months ago
[This review was collected as part of a promotion.] This spray added volume to my hair, my hair typically tends to look a little lifeless because I straighten my hair but this added the perfect amount of volume to make my hair look lively. The scent smells like a high end salon product, it left my hair feeling mosturized but light which is perfect for blow drying. It’s a spray product so I sprayed a decent amount but a little does go a long way, and it brings a good amount of product so it should last me a while. I also like that it has a lock for the spray so it won’t leak when you put it in your bag.

Nourish and plump the hair.
4 months ago
[This review was collected as part of a promotion.] Redken Acidic Grow Full System Instant Densifying Spray nourishes my hair and makes it look fuller (bangs and roots) immediately after spraying.
With its lightweight formula, it doesn't weigh down or make my hair greasy. I use it after cleansing my scalp, sometimes before styling. But after 2 weeks of use, my hair loss has significantly decreased compared to regular shampoos. I think this is thanks to the product's ingredients, which nourish the scalp and create a good environment for my hair to grow.
Regarding the scent: It's quite pleasant and not strongly chemical-smelling.
Detangling ability: My hair doesn't detangle.
My advice is to use the complete product line, be patient, and wait at least 2 weeks to see the changes I experienced.

Lightweight
4 months ago
[This review was collected as part of a promotion.] I spritzed this on after using the shampoo and conditioner that’s part of this same line, after my hairs towel dried but still damp. My first use I didn’t realize there was a childlock so I sat there trying to spray it awhile till I realized. It comes out more as a stream than a mist in my opinion. I have to be mindful where exactly I have the nozzle pointing to make sure it gets on my roots. I don’t use much, just a couple sprays. Then I work it around with my fingers. If I could be bothered I’d use a wide tooth comb, I did that the first time but honestly I just brush it with my normal Wet brush. When my hair fully dries, it’s not stiff or obvious product is there. It makes my hair look healthy. Quick and easy, this will be part of my hair routine now!

I love that it helps protect against heat, which is one less product I have to worry about using. It’s an all in one. Sprays great and will last for many uses. Working from scalp to the ends for salon quality hair. I would recommend to anyone needing to hydrate and revive your hair.

Almost perfect
4 months ago
[This review was collected as part of a promotion.] I’ve been using full Redken Acidic Grow Full system. Overall I’m genuinely impressed so far. The densifying spray smooths hair while adding structure and light fullness without any stiffness . I’ve noticed less breakage while styling and my hair looks more polished overall. The scent isn’t anything memorable but it’s clean and pleasant. A tea tree oil and rosemary base with a subtle hint of citrus. It smells fresh and herbal but fades after awhile on the hair. The systems works best when used together. Each product complements the others, creating healthier looking, smoother, fuller feeling hair. While the scent isn’t a standout feature, the performance is. The system creates a solid foundation for stronger fuller looking hair while supporting scalp health.

Might add volume, but can feel a bit heavy
3 months ago
[This review was collected as part of a promotion.] This was my least favorite product in the collection, but with such fine hair it’s very easily weighed down by most leave-in scalp products. The spray mechanism jammed at one point, but I was able to get it working again. The texture was a bit viscous and made my hair feel crunchy if I didn’t blow dry or brush it out thoroughly once dried. The scent is great though, and I love the packaging style. This just wasn’t a great fit for my hair type and how I like to style it, but I think it could be a great prep product for updos.

Clean and fresh

[This review was collected as part of a promotion.] This densifying spray works great with the rest of the system. It is the last application in the hair growth system and you spray it onto your scalp and then comb it through. The main thing I notice, even after following directions, is the I will have residue in the spots where I spray directly, even after I comb through and style. It’s not really bothersome and I otherwise love the way it makes my hair feel. I have been seeing new hair growth coming in and I love the fresh scent of this product. Highly recommend!

Confusing instructions
3 months ago
[This review was collected as part of a promotion.] I personally was not the biggest fan of this product. I felt like the instructions didn’t explain well when to use it. I used it after washing my hair one night and the next day my hair felt very hard and kind of crunchy. I do like the spray of the product because it did spray really well. And the scent is very nice. But I just feel the product lacked good detail of instructions which made it kind of hard to figure out if this was the product to use as a serum or just a product to use as like hairspray.

We appreciate your honest feedback. At Redken, we aim for professional results with every application. It sounds like there may have been some confusion regarding the usage of One United. This is a multi-benefit treatment designed to be used on damp hair as a leave-in primer, not as a finishing hairspray. The 'crunchy' texture can occur if too much product is applied or if it is used on dry hair. We would love to help you get the most out of this formula—please contact our team at 877-254-9949 (M-F 9:00 am – 5:00 pm ET) for personalized usage tips for your hair type.

Love!

[This review was collected as part of a promotion.] I’m always very hesitant to spray any products on my roots because I have very fine hair and it easily gets greasy. But after using the entire Acidic growth system, my hair felt thicker and more volumized, and I actually feel like I could go longer between washes!! It’s so hard to find products that don’t leave me greasy. I use the full line - shampoo, conditioner, serum, then spray, and am seeing beautiful results. Healthier and thicker hair. Love the light fragrance of the line too.

“If you’re looking for instant volume and density, this spray is the answer. The Instant Densifying Spray does exactly what it promises — my fine hair looks and feels thicker right away. In addition to adding body, it also improves overall texture and shine, and it really helps during the blow-drying process. It’s easy to use, and the confidence boost it gives is priceless.

This leaves me with sticky, thick spots. Maybe my bottle just has a sprayer problem.. I’m not sure. This product feels too heavy for my fine hair, which prevents me from having volume. My hair feels weighed down when using this product. The smell is fine, and I haven’t noticed any reactions in my scalp. I will keep using this to hopefully get success!

We want you to love it too! Sticky spots are definitely not the Redken way—try rinsing the nozzle under warm water to ensure a fine, even mist. If that doesn't clear things up, please call our experts at 877-254-9949 (M-F 9:00 am – 5:00 pm ET) so we can look into your bottle! ✨

Lightweight, but Underwhelming
2 months ago
[This review was collected as part of a promotion.] I like this spray because it is lightweight and non-greasy, but I didn’t see much of a difference as far as adding volume to my hair or reducing thinning hair long-term. I don’t think this is that much better than other similar products on the market. Also, since this is 1 of 4 steps in the Redken Acidic Grow Full System, I must add that the entire 4-step “system” is far too many products for me to utilize. I would prefer one, single product to add to my existing hair-care routine.

Boost for thin flat hair
4 months ago
[This review was collected as part of a promotion.] The final step I use in Redken acidic grow full system is the density spray while my hair is still damp. The spray distributes evenly and doesn't leave a sticky or heavy feeling. It adds a bit of grip and body, which helps my natural thin, flat hair look fuller when it dries. I like how it layers well with the serum without weighing my hair down. The density spray has bright citrus scent, keeping the whole routine cohesive. My hair feels light, fresh and more lifted after styling.
