Renpure Biotin & Collagen Leave-In Hair Treatment - For Fuller, Thicker Looking Hair That Shines - For Fine Hair - Vitamin B7 (Biotin), Collagen - 8 Fl Oz

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!

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.

Tried after aloe Vera and it cuts like spoiled milk but on its own it’s nice just don’t use something else as well Good pump so far

You know what's weird? I didn't like this when I first started using it, like I don't know why, I think I just expected something different but over the past few months it really grew on me lol . I will buy it again. I don't know if it made my hair grow but it did make my hair feel thicker. And that's a good feeling.

It makes my hair softer and easier to detangle my wet hair, but less is more when you have fine hair. Too much will make it seem greasy. It does help my hair retain moisture. The scent isn’t unpleasant but does seem a bit strong to me. I am ultra-sensitive to some fragrances, so others may not find it overpowering. I also thought it would be a spray like another leave-in that I used to buy before they discontinued it. Sadly, it’s not the replacement I had hoped for. Even though it is a “spray” bottle the product is way too thick to actually spray. I am a bit disappointed because I like Renpure products overall. I have been using their shampoos for several years and love them. I will most likely try to find another solution when it runs out since I personally prefer a lightweight spray leave-in.
