I consulted my doc before taking these so perhaps you are deficient in other vitamins that can be affecting your hair growth. Personally, these have been helping me! Magnesium helps maintain muscle function in the scalp which improves circulation and delivers nutrients to hair follicles. Vitamin D3 can stimulate new hair follicles helping the hair maintain thickness and prevent existing hair from falling out prematurely. Iron helps your body produce hemoglobin a protein in red blood cells that carries oxygen to cells including the ones that help with hair growth. HSN - The biotin helps enzymes metabolize glucose fatty acids and amino acids which are used to build proteins A biotin deficiency can lead to hair loss brittle nails and skin infections! Collagen is an anti-aging protein that can help prevent age related hair loss. Disclaimer: no copyright music from CapCut. #haircare
