These capsules typically contain active ingredients like biotin, keratin, vitamins (such as Vitamin E and Vitamin D), minerals, and antioxidants that support hair growth, strengthen strands, reduce hair loss, and promote shine. The ingredients help nourish the scalp, improve hair texture, and may address issues like thinning or breakage. Taken orally, these capsules work alongside external hair treatments to improve overall hair health. Its important to consult with a healthcare provider before starting any supplement regimen.
