What is it?
Vitamin D is a fat-soluble vitamin that is essential for the body to function properly. It is involved in a variety of processes in the body, including the absorption of calcium and the regulation of the immune system. Some people believe that vitamin D may be effective at improving hair growth due to its role in maintaining healthy hair. Vitamin D is necessary for the production of keratin, a protein that is found in hair, and it may help to nourish the hair and scalp, improving the overall health and appearance of the hair. Additionally, vitamin D is believed to have anti-inflammatory properties that may help to reduce dandruff and an itchy scalp.
