I received a sample of this so I only used it once and have no idea what the price is on it. I know that the ingredients in it are wonderful. It strengthens and protects your hair and is great for people struggling with constant split ends. It helps to restore and prevent further split ends. My hair loves this and results for it came right after use. My hair felt healthier after I used it. There is no real way to heal split ends other than to trim them, but this really helped my hair to become stronger despite the damaged ends. It made it grow faster too

Review for: Extreme Shampoo Fortifier For Distressed Hair 10.1 oz more...
It's a good product for short term use. It has a lot of protein in it, and made my hair slippery and no texture or body. However it did really repair my hair after an unfortunate accident at the salon. They died my hair black not red, then had to bleach it out and re dye it. My hair was dried and fried. About 2 weeks later, my hair was super soft but too soft. A little goes a long way. I keep it around for after swimming in salt water or too heavily chlorinated pools and I need something to revive my dry locks.

Review for: Redken New Nouveau Extreme Shampoo, 33.8 ounces Bottle more...
I have super long hair that’s naturally wavy and can be very frizzy. I straighten my hair quite a bit and the ends are dry and damaged. I was looking for a shampoo and conditioner duo that would repair my hair and I stumbled upon this. After just one use my hair was shiny, silky and frizz free! I kept getting compliments on my hair and I haven’t resorted to a new shampoo and conditioner for years.

Review for: Redken Extreme Shampoo more...
Redken is overall a brand that I enjoy using for my hair. This shampoo was an alright shampoo in comparison to some other shampoo brands I use. The smell was good but not my favorite. Like many high end shampoos, this shampoo lathers better on the second wash. I find Redken’s branding to be off-putting as they have many different lines that look very different from each other. It is hard to tell which products are true salon quality products and which products are just average old products. I would consider this shampoo a more average product. It definitely is better than most drugstore shampoos, and it is a high quality shampoo, but I like other brands and products more. Overall I would say if you are a Redken fan to give it a try and if you find a deal on this product give it a try.

i firmly believe using this is conjunction with the extreme primer and sealer that this WILL MAKE YOUR HAIR GROW. theres tons of protein in these products so i definitely dont recommend for every day use but like i said, if you follow the system and the manufacturer’s instructions your hair will grow up to 6 inches in a 12 month period of regular usage!

I have severely damaged hair; naturally curly and straightened everyday, plus I get it bleached every 8 weeks. It’s bad. This shampoo has helped improve the quality and integrity of my hair. I’m sure people will say purple shampoo is the best but I feel like this brand and line does wonders for me!

Review for: Redken Extreme Shampoo more...
I spent $100 on the whole Redken Extreme like because I’m trying to get my hair healthy after goin blonde and then back to brunette. I have been using this product for about a week and a half and I’ve seen none, if not worse, changes to my hair. I’m hoping with more time it’ll get better but other reviewers said they saw results within a day or two. I’ve got nothing.
Update: after using for about a month, my hair feels the way it did before I started dying it. 😊

This sis the best shampoo I’ve used and fixed my dry brittle hair. This helps split ends dry hair and damaged hair from coloring or heat damage. This shampoo is good for oily scalps. This it the only shampoo I’ve been using for 2 years and I can’t think of even switching it.

I would and will continue to buy this. I have dark hair that i ombré with blonde so it can be quite damaged and tangly. This shampoo though has made a world of difference. Love love love everything about its formula, smell, packaging, anything. Get this no matter what.

Review for: Redken Travel Size Extreme Shampoo more...
For the longest time my hair was going through a dry spell. I would get huge rats nest knots, my hair would break, and it would just lay flat on my head with no volume or body, but plenty of frizz!! Then I tried this redkin extreme shampoo and it's really been a game changer for me! My hair is so much stronger, it doesn't break, it's voluminous and shiny even though I have very curly hair!! Just after a few washes it's changed my hair completely! After I tried the sample I ended up getting the jumbo size!!! I would definitely recommend!

For those who also suffer with dandruff: would you guys recommend this? My hair was super damaged. I got a cut and treatment this week. And the stylist uses redken products but I'm iffy because although I love how it left my hair I don't want my dandruff to flair up again 😩
