Which vitamin deficiency contributes to hair loss and supports hair growth?
Hair loss can be caused by various factors, including vitamin deficiencies. Key vitamins that support hair health include vitamin B (especially biotin, B12, and folate), vitamin D, vitamin A, vitamin E, and vitamin B2. These vitamins help maintain a healthy scalp, promote hair growth, improve blood circulation, and ensure proper nutrient delivery to hair follicles. Deficiencies in any of these vitamins can lead to hair thinning and shedding.
