Why do people take collagen for better hair?
People take collagen for better hair because it helps make hair strong, thick and healthy. Collagen gives the body amino acids that are used to build keratin, the main protein in hair. It also supports the scalp , helps with blood flow and keeps hair roots healthy. As we age, our natural collagen goes down, which can cause hair to become thin or weak. Taking collagen may improve hair growth and reduce hair fall.
