Regrowing hair requires a multifaceted approach that includes living a healthy lifestyle, managing stress, eating a balanced diet rich in essential nutrients like vitamins A, C, D, and E, biotin, and iron, using gentle hair care products, avoiding excessive heat styling, and protecting hair from environmental damage. In addition, medicines such as minoxidil, finasteride, PRP therapy, and low-level laser therapy can promote hair growth. Consulting a hair specialist will help you determine the optimal regeneration treatments for your specific circumstances.
