## Description

Indulge in the luscious experience of Renpure Biotin & Collagen Thickening Leave-In Treatment. Crafted with nutrient-rich Biotin and fortifying Collagen, this treatment leaves fine hair feeling fuller, denser, and full of body. Formulated to nourish fine hair with lightweight conditioning, it ensures beautifully smooth and shiny hair.

Review: Great Product! - Great product, adds weight / shape to my very fine hair, while leaving it soft / clean…something I was not able to obtain with gels, pastes, sprays and mousse. I will definitely purchase again. Also, it smells great!
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.
