Dallas Biotin Thickening Treatment by R+Co

The weekly reset for fine hair. Used in place of conditioner, this rinse-off thickening treatment plumps each individual strand of hair with biotin, hydrolyzed rice protein, and shea butter to deliver instant body, strength, and flyaway control that lasts for up to ten washes. Hair feels noticeably thicker, stronger, and more voluminous, whether you blow-dry, air-dry, or diffuse.
