King C. Gillette is a complete line of precision grooming tools and facial hair care products from Gillette. Inspired by our founder and crafted with over 100 years of expertise in helping men discover and master their personal style, our lineup gives you everything you need to craft, maintain, and care for any facial hair look. The King C. Gillette Beard Thickener is a serum that makes men's beards look and feel noticeably thick. Infused with Vitamin B3 (Niacinamide), Pro-Vitamin B5 (Panthenol), argan oil, and caffeine, our beard thickener coats every hair, strengthening and thickening each strand. This protects against breakage and makes beards look thick and full. Our Beard Thickener also conditions hairs to soften and smooth edges for comfort. Plus, it has a lightweight fast drying formula that soothes and cools skin for a refreshing grooming experience. And to top it all off, each drop has the fragrance of signature scent, for a beard that smells as amazing as it looks. To use, dispense a small amount onto your hand, then rub it onto your beard.
