While Holly's longer locks are unlikely to be entirely down to vitamin D, the essential vitamin does help with hair growth.

Vitamin D plays a role in stimulating new and old hair follicles. If you're lacking in vitamin D, new hair growth can be stunted, so supplementing can help support healthy hair growth.
