Hair growth and thickness can be significantly enhanced with the right supplements. In 2025, the 10 best supplements for hair growth and thickness include biotin, which promotes keratin production; collagen, known for strengthening hair; and vitamin D, essential for hair follicle cycling. Other notable options are iron, which prevents hair loss; omega-3 fatty acids for scalp health; and saw palmetto, which may block DHT. Additionally, zinc supports hair tissue growth, while folic acid aids in cell division. Lastly, horsetail extract is rich in silica, promoting overall hair strength. Incorporating these supplements into your routine can lead to healthier, thicker hair.
