    • Big Hair Volume
Size: 8.5 Fl Oz (Pack of 1)
SMELLS GREAT and not sticky. Once you work through your hair it looks and feels thick. I have baby fine hair and this product gives you a lift and no breakage...just voluminous Texas Hair.

My wife purchases this hair conditioner every two months and she seems to be very happy with the quality and ingredients that maintain her hair at 75 years old looking fabulous.

    • R+Co hair products rules!!
Size: 8.5 Fl Oz (Pack of 1)
I have very thin, fine hair. Every hair conditioner I have used weighs my hair down so much I am unable to keep it styled. I can now style my hair with lots of body that stays soft and beautiful 🌸

    • Decent Product-Poor Packaging
Size: 8.5 Fl Oz (Pack of 1)
I thought the shampoo and conditioner were okay and probably did improve the look of my hair in terms of volume. I did not like the bottles. It was impossible to get the thick conditioner to come through the flip top lid. I doubt the plastic bottles are recyclable. I switched to the brand with the refillable aluminum bottles. That product works at least as well, is easier to use and the bottles can definitely be recycled. ... show more

    • Goodbye "bad hair" days!
Size: 8.5 Fl Oz (Pack of 1)
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. ... show more
