What provides nutrients for hair follicles?

Hair follicles receive nutrients primarily from the blood supply that delivers essential vitamins, minerals, and proteins. Key nutrients include biotin, zinc, iron, and vitamins A, C, D, and E, which support hair growth and health. Additionally, a balanced diet rich in these nutrients can enhance follicle function and promote stronger, healthier hair. Proper hydration also plays a vital role in maintaining overall hair health.
