5.0 out of 5 stars Goodbye "bad hair" days!
Reviewed in the United States on January 16, 2024
Size: 8.5 Fl Oz (Pack of 1)Verified Purchase
After losing my hair to chemo and radiation which I happily did because I am now a cancer survivor, I was left with hair that was both curly and straight and hard to do much with. My stylist recommended the shampoo and conditioner to me and after just a few uses, I saw my hair normalizing. Instead of having random curly areas, I found my hair was becoming more consistently straight so I could dry it in a chin length style( shorter in back, longer on the sides) and not have one side and half of the back curl up while the rest just hung. It also makes my hair much more manageable without being too soft and overconditioned ( read, oily looking).
I highly recommend this product and will look into their other ones because of my experience with their shampoo and conditioner.

For the price, it is really nice. It makes my hair feel fuller and soft. The scent is kinda lacking though.

It is expensive, but it lasts a long time. You only need a very small amount and it works well I do recommend it.

5.0 out of 5 stars My Favorite Thickening Wash
Reviewed in the United States on June 1, 2022
Size: 33.8 Fl Oz (Pack of 1)Verified Purchase
I've got baby fine hair, but lots of it, that tends to have flyaways, as well as lack volume, and think I have tried just about every thickening shampoo out there. This pricey option is my current favorite. Paired with the matching R+Co shampoo my hair has never looked healthier and does indeed have more volume, without becoming dry and flyaway. The pump dispenser on the large size is easy to use in the shower and though pricey they last a long time.

3.0 out of 5 stars It arrived without a lid!
Reviewed in the United States on March 10, 2024
Size: 8.5 Fl Oz (Pack of 1)Verified Purchase
The conditioner arrived without a lid. The seal on the product was still intact, but there was no lid to the bottle when I opened the package. How on earth did that get missed. I’m still using it since the seal wasn’t broken and didn’t appear to be tampered with but it’s a bit disconcerting to spend this kind of money and you don’t get a lid to your bottle. How do manage that after you open the product? Good thing I still had my old bottle of conditioner. I just used the lid from that. We will see if the product is the quality I’ve come to expect or not.
