Rated 5 out of 5 by from MY FAV REDKEN SHAMPOO I am a redken lover and this has been my go to shampoo set for three years now

Rated 5 out of 5 by from Does what it's designed to do I have been using this product, personally, and I LOVE it and confidently say it works! The shampoo is so light and doesn't weigh my hair down and it leaves my hair feeling so clean. The smell is also very yummy. A client of mine has also started using it, not for growth purposes but she wanted something light, and the next time she came in for her appointment she RAVED about the shampoo AND we noticed how much her hair grew since the last time I saw her!

Rated 5 out of 5 by from Love this! I have level 10, heavily processed hair that often struggles with breakage and dryness - since I have switched to the Redken Extreme Length system, I have noticed an extreme change in my hair! I’m no longer experiencing the same amount of breakage when I wash, and even when it’s dry, it feels so much stronger and softer. It definitely feels as if it’s helping me retain my length!

Rated 2 out of 5 by from So drying Im not sure what I expected but it dried out my hair so much from only ONE wash. I let my hair air dry and it looked absolutely terrible. Every flyaway on my head was present and my hair was dry to the bone. Not sure how this is supposed to make your hair longer if it dries it out.

Rated 5 out of 5 by from The best Redken formula [Employee of saloncentric] The best Redken shampoo. It really does make your hair grow. Started using this shampoo 5 years ago and my hair started at shoulder length and within a year was down to my waist. Also helps repair and stops shedding at the scalp. I also use the extreme length hair mask and conditioner.

Rated 3 out of 5 by from didn’t wow me Honestly, this dried out my hair more than most shampoos. And I found that my scalp was dry after using the whole bottle. Didn’t really think it was worth it. It has a fun smell, blue raspberry I think. But I think I needed more moisturizing shampoo.
