Rated 4 out of 5 by from Smells amazing, hair feels clean and soft without feeling stripped or waxy. I have very long fine hair and it does seem to get oily faster with this line than others ive used but overall a good product if you can live with washing a bit more frequently.

For years it did not pass the middle of my back and now my hair down to my butt. Everyone ask me if I have extensions in my hair now and I’m like nope it’s this extreme length shampoo.

Rated 5 out of 5 by from This shampoo has vitamins! [Employee of saloncentric] Extreme length has biotin to help grow the hair & has a Ph Balance to help close the cuticle allowing it to seal the color longevity and help with breakage.

Rated 5 out of 5 by from Amazing Product! I love this shampoo/conditioner. My clients are obsessed with it and you can truly see a huge difference in around 6 weeks with this product.

Rated 1 out of 5 by from Redken isn’t the same - or Salon C has counterfeit Absolute crap. I used to love this product. It’s not at all what it used to be. Wish I didn’t blow that much money of 3 of these.
