  • Healthier hair!
Size: 10.1 Fl Oz (Pack of 1)
This shampoo leaves my hair super soft after every wash. I feel like my hair has grown more since I started using them, and I’ve noticed way less breakage. My hair looks healthier and feels stronger overall. I’m really happy with the results and would definitely recommend it!

  • My hair is long and soft .
Size: 10.1 Fl Oz (Pack of 1)
It really helps. My daughter is using it. I couldn’t believe how much her hair grew! I had to purchase, it does work and my hair is so healthy and long. I will also alternate with SO Soft by Redken.

  • Good quality

I’m not sure if my hair has gotten any longer but I can tell a difference in the thickness and how healthy it looks and feels

  • Daughter mostly likes it
Size: 10.1 Fl Oz (Pack of 1)
My daughter loves this shampoo, and says that it's helped her with hair loss from lupus. It does leave her with noticeably greasy hair though, so she's had to start alternating with a clarifying shampoo once or twice a week. The bottle has lasted a reasonable amount of time, given the price.

  • Repaired my damage!
Size: 10.1 Fl Oz (Pack of 1)
I just want to say that this product has grown my hair at an insane rate. For starters, I have been on a hair care journey for almost 6 months after taking out tape-in extensions and finding my hair at the worst state it’s ever been in. I have natural very thin hair so this didn’t help my already insecurity about that. It was Dry, brittle, noticeably see-through, and thinning. I knew it would take time to see results but kept trying. I started with the extreme repair and just recently made a switch to the extreme length when I saw improvements. I have been actively cutting my ends off to get rid of the dead ends from 6 months ago. I have been trimming regularly. My hair has returned to its thickness, is shiny, and grew my hair so long in just 5 months. I also use the redken blowout/thermal spray and redken acidic hair mask and leave in conditioner(not every wash). I am so thankful for finding this product. I never write reviews but had to just explain how thankful I am. ... show more

  • Made my hair feel and look great!
Size: 10.1 Fl Oz (Pack of 1)
I purchased this a couple months leading up to my wedding. It made my hair so soft. I typically have very dry crusty curls, but it smoothed it out and seemed to help the volume. I would compare the feeling to a fresh hair cut. I’m not sure how much my hair grew, but I was pleased with my hair at my wedding! ... show more
