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

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!

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.

My son has curly hair and live this product. It thickens and conditions well

Excellent produit il fait ce qu’il promet, en plus la senteur est exquise je recommande ce produit sans hésitation !!!

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.
