- Q
So, is it safe to say that this isn't a good choice for color treated hair? Ingredients say it has sulfates?
- Asked by Linz
- Official Answer By Redken - BEHi there, Extreme Length Shampoo, ideal for all hair types and textures seeking longer hair, is safe for color-treated hair. We use sulfates (SLS, SLES, ALS) derived from vegetable sources in our rinse-off products at concentrations ensuring effective cleansing without compromising scalp or skin tolerance. These sulfates create the foaming action that removes dirt and impurities, and due to short contact time, pose minimal risk of irritation. We advise checking the ingredient list on product packaging to identify them.Was this answer helpful to you

My Fave!!
About 9 months ago I was sent this shampoo, conditioner and leave in treatment to review by a third party company. I have to admit, the first thing I noticed was the scent. It's marvelous!! The second thing I noticed is that after a couple of uses, my hair didn't break near as much. There wasn't a l...

Scent is wonderful, overall product not as much
I received this product to try for free in exchange for sharing my opinion about it. I have fine hair that lacks volume, as well as certain pieces that don't really seem to be growing at all, so I was very excited to try this product. The first thing that I noticed about it was the scent. Wow! This ...

Redken, extreme lengths, shampoo and conditioner
I was so excited when I found out that the shampoo was back in stock. I've been wanting to try this brand well I love Redken, but this is one of Redkens I am not a fan of. I loved all the reviews so I went and got it to try it and I will be returning it as soon as I can make it back to the store. It makes my hair very dry. Very dried out very dull looking no shine whatsoever just very dull and very dry like hey which is a bummer because I was excited to try it and hoped that I liked it smells great, but that's all for me anyway. I LOVE the Acid Gloss Shampoo and Conditioner that one is the best! Will be exchanging these for those. I got the small travel size ones of the Acid Gloss and should had just paid the price and got the regular size ones instead of the exterme lengths.
Will keep repurchasing!
This shampoo has truly improved the health of my hair! For years, my hair would stop growing once it got to a certain length. This has helped it grow past that and pretty quickly! It's also helped with hair loss! I used to lose chunks of hair when I showered and now, I only lose like 1/4 of what I used to lose!
Smells amazing, works even better!!
Hair Type Wavy Hair
My hair has never felt cleaner after a wash, and it smells amazing!!
It works!
Hair Type Wavy Hair
it's so good in need of damage repair and it works just a little itchy on the scalp but don't use it too much 🫶🏻
Worth it!! All hair types 
I am on a hair care journey. I want to grow 3 inches of hair by December and it is now in the middle of August. I have foresee hair, low porosity, and about bra strap hair length in the back and a little past shoulder in the front. My hair is extremely damaged. I have always used their mega soft curls and thought that penetrated my hair well. I went ahead and bought their acidic bonding curls, shampoo and extreme length shampoo and conditioner. I put both in my hair last night, blow dry my hair with a little heat protected and very light oil . Honestly, I can tell that the extreme length has something in it because my hair feels extremely more sturdy, almost as if it's thicker. Like it was coded with something, but my hair is soft and flowing. I decided to trim my ends and I will report back with how much hair growth I have but definitely I can see how this makes your hair stronger from breaking because I physically feel stronger and I've never had a product do that before.
