Long, strong hair
2 years ago
[This review was collected as part of a promotion.] Here are some of the things that I love about Redken Extreme Length Sealer Leave-In Treatment:
It is formulated with biotin, which helps to strengthen and repair damaged hair.
It is lightweight and non-greasy, so it does not weigh my hair down.
It leaves my hair feeling soft, smooth, and shiny.
It helps to reduce frizz and flyaways.
It protects my hair from heat styling damage.
It is easy to find and affordable.
If you are looking for a leave-in treatment that will help you achieve long, healthy hair, I highly recommend Redken Extreme Length Sealer Leave-In Treatment. It is the best leave-in treatment that I have ever used, and I am so glad that I found it.
Yes, I recommend this product.

SAVED my hair. I'm now on my third pump. Great value for money. If you're desperate and your hair is growing but keeps breaking midway, this will work.
I use this together with the primer and this was my review for tbat: After damaging my hair with a cheap hair straightener (to it's defence, I went from hair drying my full head of bog curls to straightening my stress-induced brittle hair several times a week). It SAVED MY HAIR. I've been using it for almost a year now, together with the sealer and can honestly say that I haven't had a single split end since. My hair was breaking mid-shaft and is now growing healthy. Love.

Natural, Low Porosity, Dense Hair
a month ago
I recently began using this product, and by the midpoint of this month, it has completely transformed my hair. I frequently have trouble protecting my ends in between ahir salon visits which results in me having to cut off a lot of hair per visit. This is first time I’ve used a product that genuinely feels like it is protecting my hair and can visually see a difference in my hair. I predominantly wear my hair in stretched styles to prevent knotting and this product had only aided in my hair growth journey. My blowouts last up to two weeks ( I typically wash my hair once a week but may need to stretch it for work) without any flaking or product build up. Get it now!
Yes, I recommend this product.

Part of an excellent treatment system
2 years ago
[This review was collected as part of a promotion.] I received this for free in exchange for my honest opinion. This leave-in sealer is part of a three-product treatment system that helps your hair look and become stronger and grow faster. The packaging is modern and sleek, and the bottle color is gorgeous. It has a flip-top lid that's easy to open. The scent is amazing! It's slightly spicy and I can smell a slight hint of it for several days after wash day. I apply this to my damp hair from mid-strand to ends, and then I style it as usual. After using all 3 products a few times, my long, fine, curly hair is already looking and feeling healthier and stronger!
Yes, I recommend this product.

Best Redken leave in
2 years ago
[This review was collected as part of a promotion.] I had the opportunity to try this product out for free and exchange for my honest review. I've used a few Redken leave in product in the past and my experience was hit or miss so it put me off from trying other Redken products. However, trying this entire line, I had an amazing experience, and this has become my new favorite. The bottle is small, clear and aesthetic and fits perfectly on my shower caddy holder. A little goes a long way with the leav in conditioner, and it spreads well on wet hair. It smells good and leaves my hair feeling clean, soft, smelling good and smooth. In terms of the biotin helping hair grow, I haven't noticed any faster growth, but I have noticed that my hair has stopped falling out significantly.
Yes, I recommend this product.

RUN TO BUY THIS PRODUCT
2 years ago
[This review was collected as part of a promotion.] OMG!!!! this leave-in treatment works wonders! I received this Treatment as a sample in the mail from BzzAgent. the scent isn't too strong, but IS AMAZING! I only use about a dime size amount and work it mainly focusing on my ends, and working my way up on damp hair. I love the way my hair feels instantly when I put this product on! I feel like my hair is already bonding back together (as I have damaged bleached hair) and makes my hair feel so soft and flowy when my hair is dry! I highly recommend this product and will for sure be a new staple in my collection!
Yes, I recommend this product.

I love this leave-in treatment
2 years ago
[This review was collected as part of a promotion.] I used this leave-in treatment in conjunction with the shampoo, and conditioner. It doesn't leave the hair greasy or feeling weighed down. The bottle is pretty, and it smells so good. My skin is combination, so normally by noon the next day my hair is greasy. With this set, I was able to go another day without washing my hair. It's absolutely amazing. I will not be going back to my old shampoo, or conditioner. I never used a leave-in treatment before. But, I love how this makes my hair feel.
Yes, I recommend this product.

I love this leave-in treatment!
2 years ago
[This review was collected as part of a promotion.] I received a complimentary bottle of this leave-in treatment in exchange for my honest review. I have fine hair that lacks volume, so I was very excited to try this product. I have used it for about 2 weeks and so far I am very happy with it. A little goes a long way. My hair looks and feels healthier when using this leave-in treatment. It even seems a little stronger. I love the scent. It makes my hair smell fantastic. I would definitely recommend this product.

No more split ends!
2 years ago
[This review was collected as part of a promotion.] LOVE this product! One of the best leave-in treatments I have used. I have thick, curly hair, so finding hair products can sometimes be a challenge. I love all the extreme length products, but this might be my favorite. I love that it leaves my hair feeling soft, and there is NO sticky residue. I would consider my hair healthy, but definitely tend to get split ends from straightening my hair occasionally. This has worked wonders, and I'll definitely be buying again.
Yes, I recommend this product.

I am a professional. I just used this for the first time on my own hair. I have heavily color treated blonde hair. And immediately after i used it I FELT a difference in just running my fingers through my hair. It was like butter. No tangles, it was visibly shiner and as well as with no tangles i didn’t feel the split end roughness as most hair has when they have split ends. As this is my first time using im curious to see how to helps in the future!

Great Product
2 years ago
[This review was collected as part of a promotion.] I received this Redken Extreme Length Sealer Leave-In Treatment as part of the 3 piece complete system and have only used it for about 2 weeks every time I shower and so far I like it.It smells nice and it doesn't leave my hair feeling greasy. I think it will take more time to see the advertised results, but I will definitely be purchasing more of this and would recommend it to anyone with fine, thin hair or who wants to grow their hair.

Hair is stronger and feels great!
2 years ago
[This review was collected as part of a promotion.] I have been using this product for a bit since getting it free in exchange for a review. Since I have started using it, I've noticed my hair looking healthier. I have long, thick hair that I color and get highlights to regularly, so it has been damaged over the years. I want to continue to grow my hair and I feel like this product will allow that to happen by strengthening it. I highly recommend it to those that have damaged hair!
Yes, I recommend this product.

I started using this when I was trying to grow my hair out and cure my awful split ends. My hairdresser sold this to me and highly recommended it. I do love the way it smells and a little goes a long way so it lasts a long time. It is very affordable, although I'm not crazy about the brush on the end of the tube so I squirted it into my hand and applied with my fingers. It helped with my split ends but not so much the length.

I'm wasn't sure if this product did anything until I went back to my salon for a haircut and my stylist said my ends don't look bad at all. I blow dry and/ or curl my hair on a daily basis. The product literally has a brush tip like a paint brush for an end and you literally brush the product on your ends. The consistency is like a lotion. Don't squeeze too much/ hard or you'll end up with too much on the brush tip.

Miracle in a bottle

[This review was collected as part of a promotion.] I was lucky enough to receive a sample of this product via BzzAgent. After i washed my hair with the shampoo and conditioner, I applied a small amount to my hair and distributed it evenly. And then allowed my hair to be air dried in order to see the true results. Once my hair was dry I was pretty much in shock. Ive always struggled with my hair and this leave in treatment left my hair shiny, Smooth, soft and NO FRIZZ

My hair was completely dried out and damaged after using purple shampoo but this product manages to make my hair sleek after a quick straightening session without further damaging my hair. I only used on the ends in which they're the most damaged and I've found that it helps. Also, by not applying it all over, my hair doesn't become a greaseball! I truly recommend this product. Definitely worth every penny spent.

NOW THIS! Crème de la crème of leave in!
2 years ago
[This review was collected as part of a promotion.] You need to use this with the system, the conditioner and the leave in that comes with it. I LOVE this leave in! It makes it to where we don't have to add a bunch of different products in our hair and I'm soooo happy about that 😅 like it makes the hair soft and easy to manage even after our hair dries up. I am not to crazy about the smell. You won't see results until about 2 weeks of frequent usage.
Yes, I recommend this product.

My stylist suggested this product and I am in love with it. About two years ago I started dying my hair (which was still partially dyed black) blonde and completely damaged my hair after doing it for about a year. This products makes my hair fee much smoothr and healthier. I use it as my conditioner. It feels safe to straighten my hair again!! This is perfect.

wonderful product. i LOVE this stuff.. but just like the mega mask, whats with the packaging? the brush tip makes application terrible. i find my self getting frustrated with it and squirting the product into my hand. and then of course the brush holds product and the product dries and gunks up and then i find my self digging dried product out of it to use it.

Lightweight and leaves hair silky
2 years ago
[This review was collected as part of a promotion.] I was a little wary of using so many products in a hair care routine but this made using the multi step process worth it. I don't use a lot for my hair because it's easy to work into my damp hair. After a blow dry, I'm very happy - it leaves my hair silky and not weighed down and smells great. I think this is the best part between the shampoo and conditioner.
Yes, I recommend this product.

Redken Extreme Length Sealer Split-End Treatment has made a huge difference in my hair! I apply this to the damaged ends of my hair after washing and towel drying, and while it is not a miracle worker, it really does help seal my split ends so my looks and feels much less damaged. I have really enjoyed using this entire line of Redken products!

This stuff is so amazing. In the last 2 months I've gotten highlights twice on hair that had been colored dark brown which before that I was completely blonde. And ive also done a bleach bath to remove color. I normally just flat iron my hair and add some in to my ends and it really makes a difference. My hair looks more sleek and put together.

[This review was collected as part of a promotion.] I love to use this product on second day hair right before bed. it gives the product a chance to seep into the hair and help heal split ends. I also use Redken's acidic bonding concentrate on the days that I don't use this to make my hair's pH is at the optimal level longer. I love this and redken makes amazing hair care!

Soft scent. Less frizz
2 years ago
[This review was collected as part of a promotion.] I've used this in my hair 3 times. It has a very soft pleasant scent. My hair is noticeably less frizzy and easier to comb through. I have soft waves and my hair did not get frizzy as fast when I went outside in heat. It's holding styles very well. I would lile more scent, it's very mild. But some might prefer that.
Yes, I recommend this product.

I have fine fragile hair. This product is a wonderful treatment on those ends after conditioning for protecting what you have already grown. Providing a lightweight application enhances the strength of my hair. Trust me when I say I have baby fine hair. I rate this product a must buy with the shampoo and conditioner.

It was received as a sample for a review, and I am pleased to report that it has truly helped my hair!

Made my fried hair feel awesome but I do NOT recommend applying it with the attached brush. Instead I rub it between my palms and apply it evenly to my ends then comb through. You don't get much product for the price but if it will continue to make my hair feel like this I will continue to purchase!
