This really works!
I have tried so many shampoos that say they will thicken my hair, and then they all fall flat. This R+Co shampoo really works! I have thin blonde hair and this shampoo has made my hair feel thick and full! Amazing product!!!!

Damaged Hair
Since using this my hair has become dry and damaged. It falls out and breaks off easily. The worst shampoo product I have used.

waste
Takes 1/4 of a cup to distribute throughout my short fine hair….plus it makes my hair oily within 24 hours. What happened to the television series? 10000x better. They always stop carrying the best stuff. Go to rco website.

Thicker hair without heavy residue.
I am 66 years old and really do not want to appear to have thin, dry hair. This product gives me the thickness I desire without being heavy with an added bonus of shine.
