Take Biotin supplement

Take 2500-5000mcg of biotin daily with food. Choose a standalone biotin supplement or a hair-targeted multivitamin that includes biotin at this dosage.

Why It Works

Biotin (vitamin B7) is essential for keratin production, the primary protein in hair. While true biotin deficiency is uncommon, supplementation may support hair strength and growth in women with suboptimal levels. Many dermatologists recommend it as a low-risk addition to a hair loss regimen.

Tips

• Tell your doctor you take biotin — it can interfere with certain blood test results (thyroid, troponin)
• Evidence for biotin in non-deficient individuals is limited
• Works best as part of a broader approach, not as a standalone treatment
