Kerastrength

Kerastrength is a targeted hair, skin, and nail formula combining biotin, keratin hydrolysate, silica, zinc, and amino acids to rebuild the structural proteins that give hair its strength, skin its resilience, and nails their hardness. Weak, brittle hair and nails almost always reflect a deficiency in the specific amino acids, minerals, and vitamins that form keratin and collagen scaffolding. Kerastrength addresses this deficiency comprehensively, from the inside out. True beauty is built in the cells.
