Designed for adults with thinning hair or bald spots, this vegan, sulfate- and paraben-free product is wind and sweat resistant, ensuring long-lasting coverage. Trusted by professionals and backed by over 45 years of BosleyMD expertise, it offers a scientifically advanced, cruelty-free solution to hair thinning. ## Description Product Description BosVolumize Hair Thickening Fibers naturally bond to existing hair with keratin fibers that blend and cover thinning and low density areas. Because our own hair is made of Keratin and naturally holds a positive charge, BosleyMD Hair Thickening Fibers are designed to mimic our own human hair but with a negative charge. Therefore, when negatively-charged, lightweight, easily blended BosleyMD Fibers come in contact with our positively-charged hair, it creates a static-cling effect, naturally binding to the hair shaft creating instantly thicker, fuller looking hair. Brand story BosleyMD is the Thinning Hair Authority™ & the leader in effective solutions for men & women. With over 45 years of experience, BosleyMD is the world’s most recognized & trusted name in hair restoration. Review: Review - This product works for me in my condition.

Not really, especially in the front and like around the frame of your face does not cover at all, when you shake it it gets on your face and smudges everywhere, you can't apply with a brush it does not work at all! It does however cover a the middle part on your scalp pretty good to make thin hair look fuller but again you can see grays, it also doesn't last very long if you use every day, I ended up looking into it and bought eyeshadow in black that cost. A buck and fluffy eyeshadow brush for 50 cents, I apply to the grays around my face and the part, it works awesome and covers up gray!! Not happy with any Bodley product I've ever tryed and this was a waste of money!!! Go spend the 1.50!!!! **Q: Is this product fragrance free? If not, what kind fragrance?** A: It is fragrance free **Q: What happens if the scalp sweats? Does it look darker or will it run?** A: If you swear the fibers will melt into the scalp it will look more darker or shall I say more of it looks like your trying to dye your hair with color. When I sweat it works for me because its helps blend in the fibers a little. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***E on September 5, 2025* This product works for me in my condition. ### ⭐⭐⭐⭐⭐ Quick Delivery *by C***R on September 24, 2025* Great product.
