What does hair growth come from?

Hair growth originates from hair follicles located in the skin, where specialized cells called keratinocytes produce keratin, the protein that makes up hair. This process is influenced by various factors, including genetics, hormones, and nutrition. Hair growth occurs in cycles, consisting of phases like anagen (growth), catagen (transitional), and telogen (resting). Overall, a healthy scalp and adequate blood circulation are crucial for optimal hair growth.
