Biotin is thought to improve the fundamental protein that builds up hair, skin, and nails. Keratin is the name given to this protein. A lack of biotin can result in brittle hair and hair loss. Biotin can be taken orally or administered intramuscularly as an injection. Biotin, often known as B7 or Vitamin H, is a B-complex vitamin. Biotin is required for cell development and fatty acid synthesis in living organisms.

Many supplements and vitamins are not entirely absorbed by our systems through food, so intramuscular biotin injection has helped many patients increase biotin levels faster. Correct biotin supplementation dosages have proven an improvement in hair growth, structure, and thickness, as well as a decrease in hair loss.
