Biotin
Biotin is a popular beauty supplement, especially for those concerned about thinning hair – and the benefits do not stop there. Dermatologist Dr. Michelle Henry explains to Byrdie, "It’s fundamental for the health of hair, skin, and nails."
If you are hoping for thicker, healthier locks, biotin is a good place to start.
Collagen
Collagen is another supplement that can contribute to healthier strands. "Some think that eating more collagen may transfer to hair and scalp health," New York City dermatologist Debra Jaliman, MD tells Health.
"The more collagen we have, the more youthful our skin will feel and appear, and the healthier our hair will be," she explains.
Vitamin A
Vitamin A is essential for healthy, hydrated hair. "All cells need vitamin A for growth. This includes hair, the fastest growing tissue in the human body," Healthline explains.
Plus, vitamin A can contribute to a well-nourished scalp – another necessary aspect of hair growth and health. The article continues, "Vitamin A also helps skin glands make an oily substance called sebum. Sebum moisturizes the scalp and helps keep hair healthy."
