Perque Hair, Skin and Nails Guard is a physician-grade targeted supplement delivering the specific micronutrients most critical for hair follicle health, skin integrity, and nail strength — in the fully bioavailable forms that distinguish Perque from conventional beauty supplements. 120 capsules.

Biotin (Vitamin B7) supports keratin synthesis — the structural protein of hair and nails. Silica provides the mineral backbone for connective tissue and hair and nail structural integrity. Vitamin C (mineral ascorbate form) is essential for collagen synthesis — the dermal collagen that provides skin firmness and hair follicle support. Zinc supports hair follicle cell proliferation and sebum regulation. MSM (Methylsulfonylmethane) provides the sulfur required for keratin cross-linking and collagen formation. All nutrients are delivered in their fully reduced, fully reacted, most bioavailable forms per the Perque quality standard. Perque is a physician-grade clinical nutrition brand founded by integrative medicine pioneer Dr. Russell Jaffe, M.D., Ph.D., known for using only the highest-bioavailability nutrient forms (fully reduced, fully reacted) and rigorous quality standards. Available at Beauty Riche with same-day shipping.
