Biotin supplements only help if you have a true biotin deficiency, which is actually quite rare. For severe hair fall, it is best to consult a dermatologist to identify the root cause, such as hormonal imbalances, thyroid issues, stress, or iron deficiency.\n\nProven medical treatments include topical Minoxidil to stimulate hair regrowth, and prescription medications like Spironolactone (for women) or Finasteride (for men). If blood tests reveal specific deficiencies in iron, Vitamin D, or zinc, targeted supplements will help. Please avoid self-medicating and seek a professional evaluation for a personalized, effective treatment plan.
