[This review was collected as part of a promotion.] This is the very best hair care system that I ever purchased. LOVE LOVE LOVE this product. My hair stopped shedding, and my growth rate has increased. My hair is so healthy. Thank you Redken!

[This review was collected as part of a promotion.] It worked in the beginning, but then started to dry out my hair

This is one of my favorite products. When trying to find a system to support hair health and growth, extreme lengths went above and beyond my expectations. 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!

I love this product. It helped me grow my hair so muchh!! Literally obsessed!!

I absolutely love the extreme length shampoo and conditioner! My daughter introduced me to it and I received my order last week. What a difference in just one use. My hair is long and I am in my mid 60’s. I have gotten so many compliments on the condition of my hair! I am a Redken user for life. I’m excited to try other products in the Redken lineup.

I have 4a/b hair prone to dryness. It works REALLY good in my routine. I’m not sure if it’s helped my hair grow but it makes my routine so much quicker. And my hair last way longer in between wash days without getting to dry (4-5 days). I do recommend using a clarifying shampoo first and then using this Redkin shampoo. I know it more money but I double wash anyways to promote growth, so it works in my routine.

[This review was collected as part of a promotion.] Due to processing my hair melted, having lengthy hair my entire life I was devastated, when a friend suggested Redkin Extreme Length, I purchased immediately and a year later my hair has not only grown multiple inches but is so healthy. I highly recommend the whole system!

My hair feels so good after washing and I’ve seen a difference is just a month of using it!

[This review was collected as part of a promotion.] I love this for length!! but it's not for oily hair, i'm texting out more redken shampoos to see which is best for my oily hair.

I love redken, and have been waiting to leave a review.
Back in July my hair stylist recommended this shampoo. My hair was to my waist and was wanting to see how long it could get, also super thick hair. After 1 month of this shampoo it broke my hair and I experienced severe hair loss. It is now January and my hair is finally starting to heal from this, my hair had to be cut to my shoulders. Super sad this happened to my beautiful hair and just use this product with precaution. Please know your hair. During that one month it was doing very well until it wasn’t. I would definitely have upload pictures but it wouldn’t let me.

I bought the small bottle to see if i liked it and came back for the big bottle this shampoo makes my hair feel and smell so yummy c:

I really like this shampoo! It’s works! And smells amazing

My hair has THRIVED using this shampoo... i switch between all soft conditioner and the extreme lengths conditioner.

Love this stuff! Makes my hair feel amazing and I can see the growth.
