It's formulated for women at any stage, whether dealing with seasonal shedding, stress-related hair loss, or simply wanting to improve hair strength. With a blend of 20+ nutrients, it goes beyond basic biotin supplements to address multiple aspects of hair health.

The standout feature is its advanced formula that includes Biotin 5000mcg, Saw Palmetto, Hydrolyzed Marine Collagen, and Keratin, along with amino acids like L-Cysteine and L-Lysine. This combination supports the hair's keratin structure, nourishes from root to tip, and helps reduce breakage.
