Q: Can taking a standard multivitamin stop my hair fall? A: Not always. Standard multivitamins contain very low doses of many different vitamins. To stop heavy hair fall, your hair roots need specific micronutrients at therapeutic doses. If you have a severe deficiency in specific blocks like Iron or Vitamin D, a general multivitamin won’t be strong enough to fix it. A targeted supplement prescribed by a dermatologist is what truly makes a difference.
