    Extreme Shampoo for long hair and conditioner.

    [This review was collected as part of a promotion.] My hair at 65 has never felt better. The smoothness and shine are incredible. My hair has no breakage whatsoever and the strength of my hair is just what I was looking for.

    Yes, I recommend this product.

    This is by far my favorite scent from Redken. I’ve been using this product for 3 years now and am able to grow my hair from shoulder length to mid back in a matter of 4-6 months. Also adds smoothness and shine for my dry/wavy hair. Highly recommend!

    Yes, I recommend this product.

      This system went above and beyond my expectations. I love that I can use this conditioner as a hair mask in between colorings to prevent/ restore damage and enhance my waves! My hair dresser was floored to see the restoration that took place over 6 weeks and even more so after 12, my hair was healthy and growing again!

      Yes, I recommend this product.

      My hair was breaking off when I was pregnant and once I entered postpartum, I decided to give Redken extreme length a try my hair stopped breaking and I noticed differences within 2 to 3 weeks. I would definitely recommend for my postpartum mommies.

      So I'm supposed to this with the shampoo because I got both but... This helps. Given I'm trying to grow my hair out so I'm on different medications too but coupled with this and the medications that I'm taking it is helping me regrow the bald patches that were starting to show from hair thinning.

      Yes, I recommend this product.

      I have been a customer of Redken for over a year now and have been using ABC line and absolutely love it. I just ran out I needed new products and figured I would try the extreme length (because let's be honest who doesn't want longer hair). Upon the switch, I have been EXTREMELY disappointed. My hair is falling out in CLUMPS in the shower. Not to mention my hair feels so dry, frizzy and straw like. I saw other reviews that said to pair it with a mask so that this doesn't happen. I have tried that and that still doesn't work :/ Honestly, a lot disappointed in this product, even a little scared to finish the bottle, something this expensive should NOT make my hair fall out. Going back to ABC and just gonna eat this loss. Girls for reference: I super fine pin straight hair that has never been died!

      [This review was collected as part of a promotion.] I absolutely love this conditioner! After just a few uses, my hair feels stronger, smoother, and so much healthier. It smells amazing and makes my hair super soft without weighing it down. I’ve noticed less breakage and more shine — it really helps my hair grow! Totally worth it!
