11 Expert-Approved Vitamins for Hair Growth That Actually Work

If you’re experiencing hair loss or just wishing for thicker, shinier hair, the top vitamins for hair growth are probably already familiar to you. Dr. Hardik Doshi, lead surgeon in hair restoration at Ample, emphasizes that hair loss can stem from multiple causes, including nutrient deficiencies and changes related to childbirth.

Dr. Doshi advises, “The first step should be addressing any shortages through a balanced diet rich in vital vitamins and minerals that foster overall health, support hair growth, and help reduce excessive hair loss.” While maintaining a consistent hair care regimen and focusing on scalp health are important, supplements can provide focused support. “If you’re considering dietary supplements, it’s wise to consult a healthcare professional to understand your needs, potential risks, and how they might interact with existing health issues or medications,” notes Dr. Doshi.
