Fighting hair loss can feel like a never ending battle. Just when you think things may have slowed down, you are faced with a larger than usual amount of hair in the drain after a shampoo. Minoxidil offers a partial solution, but only if you keep it up. A good diet is supposed to help build strong hair and nails but one wonders if there is something we’re just not getting enough of? Do supplements really help with hair loss or are we fooling ourselves?
According to Samantha Heller, a nutritionist at NYU Medical Center, an iron deficiency can contribute to hair loss in women. She stated in webmd.com that “the deficiency may be so slight you barely notice it but it can play a role in female hair loss.” Iron deficiencies are common during a woman’s reproductive years. The reduction of iron leads to anemia so there are fewer red blood cells available to carry oxygen to our waning hair follicles.
Another common deficiency women develop is vitamin B12 loss. Vitamin B12 can be found in foods such as eggs, meat and chicken so vegetarians are at risk of not getting enough in their diet. Vitamin B12 is needed for proper red blood cell development. Similarly to women with anemia, those with B12 deficiencies may have reduced oxygen reaching their tissues and hair follicles.
Biotin is another B vitamin that has been recognized by some as important in hair growth. It has been nicknamed, vitamin “H” for hair and has become a very popular supplement despite there not being conclusive scientific studies that support it helps with regrowth. The recommended daily intake (RDI) is only 300 mcg but doctors who treat patients for hair loss may recommend doses between 2,000 and 3,000 mcg.
Zinc and copper are two minerals important in maintaining hormone levels, which when low may be involved in hair loss. These metals are not ones that should be indiscriminately supplemented since they need to be in balance with each other. The amounts in a multivitamin are thought to be safe levels and provide adequate replacement.
