R+Co DALLAS Biotin Thickening Shampoo

They say everything’s bigger in Texas. We’re taking notes from the Lone Star State and giving our thin, limp strands a major boost of volume and shine with this thickening shampoo. An advanced polymer complex creates body and reduces static while antioxidant-rich moringa seed extract protects strands and repairs damage. The result? Big, voluminous hair that would make any Texan proud.

Not actually thickening

I didn't notice a difference in my hair's thickness when using these products (the shampoo and conditioner) together.

Not For Me
Sampled

This product might be great but it's not for me. I can't get past the scent. To me it smells like a wet dog getting a perm.

Smells Medicinal
Sampled

Smells too medicinal and left my hair feeling stripped. I'd rather use Amika and Beauty Protector brands.

Dull limp hair
Sampled

This shampoo and its partner conditioner left my hair dull, coated and limp. I have fine hair and am leery of "thickening" products for this reason.
