Niacin, also known as vitamin B3 or nicotinic acid, plays a vital role in maintaining healthy hair. It is a water-soluble vitamin that is naturally found in many foods, such as meat, fish, nuts, and beans. Niacin can also be taken as a supplement.
Niacin is essential for the production of keratin, a protein that gives hair its strength and structure. It also helps to improve blood circulation to the scalp, which can promote hair growth. Additionally, niacin is a powerful antioxidant that can help to protect hair from damage caused by free radicals.
