A good hair growth kit starts with a sulfate-free shampoo that gently cleanses the scalp without stripping its natural oils. Look for ingredients like biotin, caffeine, saw palmetto, and ginseng, all known for their follicle-stimulating properties. These shampoos help unclog hair follicles, improve blood circulation in the scalp, and reduce hair fall. They also maintain the natural pH balance of the scalp, preventing issues like dandruff or irritation, which can hinder growth.
