Collagen is a protein that is abundant in the human body and provides strength, structure, and flexibility to bones, tendons, ligaments, muscles, hair, and skin, including the scalp. While there is limited scientific evidence suggesting collagen can encourage hair growth, collagen has become a popular hair growth supplement thanks to media attention and personal reports from consumers. Here are some details about collagen and hair loss:
Positive effects:
- Collagen contains amino acids used to build keratin, which is the protein that hair is primarily made of.
- Collagen can act as an antioxidant and fight damage caused by free radicals, which can harm hair cells, proteins, and DNA.
- Collagen protects the layer of skin that contains hair roots, which may help prevent age-related hair loss and thinning.
Negative effects:
- The research on collagen supplementation is far from conclusive.
- While generally well-tolerated, some people experience gastrointestinal (GI) side effects when they take collagen supplements.
Ingredients or materials:
- Collagen supplements contain amino acids, the building blocks of protein, and some may also contain additional nutrients related to healthy skin and hair like vitamin C, biotin, or zinc.
