Indulge in the luscious experience of Renpure Biotin & Collagen Thickening Leave-In Treatment.

Review: Great Renpure product to strengthen, smooth, detangle fine hair - Long fine hair was getting badly tangled from winter hoodies so I bought this Renpure on the hope I could detangle and avoid cutting. It worked! It worked so well that I lent it for a single trial to a friend with long hair she has other problems with. You’ll probably have an order from her soon! It does seem to strengthen and smooth fine hair and smells so good too!
Review: You Will Love This For Your Fine Hair! - I absolutely love this new formula of Renpure's Biotin & Collagen leave-in conditioner! The liquid spray was good and had the same awesome distinct fragrance...This new spray bottle design is so much more efficient. The soft creamy texture of the conditioner is so smooth and velvety, not greasy, not heavy, and a little goes a LONG way!! My fine thin hair is so much more bouncy and styling with heat does not do any damage. I recommend spraying it on to your wet hands and then run your fingers through your hair starting at the ends and working your way up. I don't rinse off any excess on my hands, I rub it in to my hands/arms because i love the scent so much.
