You might think of reaching for some vitamin D3 for a boost of energy but did you know that it can actually encourage hair growth? Unlike most other vitamins, we can’t get vitamin D from the foods we eat - only from sunlight or supplementation. Trust us, you’ll want to make sure you have adequate amounts of this powerhouse - especially for your hair. Vitamin D3 doesn’t just stimulate your existing hair follicles to grow, it can actually help your body create new follicles: new follicles lead to new hair.
