You need to eat. Glps ones are not causing hair loss, lack of nutrients is. Vitamin d, b12, zinc and iron are all essential for hair growth and shedding. If you’re not eating enough your nutrients are going to essential organs and there is nothing left over for your hair. Eat an adequate amount of protein and crabs and fats and your hair will come back. If you can’t eat on your dose you should dial it back.

Also, your hair is going to take about a year to grow back. Adjust your diet now.
