Long, strong hair

3 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

2 months 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

3 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

3 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

3 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

3 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!

3 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.

Yes, I recommend this product.
