what vitamin helps thinning hair
Vitamin Imbalances. A deficiency in biotin, one of the B vitamins, can cause thinning hair in women -- so can being deficient in vitamin D, according to a review paper published in the June 2009 issue of the âCleveland Clinic Journal of Medicine.â Recommended dietary allowances for biotin and vitamin D are 30 and 15 micrograms per day, respectively.
Biotin & Zinc. Deficiencies in biotin and zinc can cause, or accelerate, hair thinning. Biotin does not cure baldness but resolves the underlying skin conditions due to deficiencies says Dr. Shari Lieberman. Get 300 micrograms of biotin daily in your supplements.
