7. One A Day Prenatal 1 Multivitamin
BEST PRENATAL VITAMINS FOR HAIR GROWTH
Whether you’re pregnant or not (and even if you don’t intend to be!), your hair can benefit from a prenatal, says Suzanne Friedler, M.D., board-certified dermatologist with Advanced Dermatology PC and clinical instructor of dermatology at Mt. Sinai Medical Center in NYC. “A prenatal vitamin has the nutrients you need to support hair growth in high enough concentrations,” she says. Prenatals are specifically often packed with iron. “Many of my patients whose hair is thinning are missing iron,” she says. The beauty of this One A Day is that it contains biotin as well as iron—28 mg (156% of your daily need).
