Hair loss can be caused by a deficiency of certain vitamins and minerals, including iron, vitamin D, folate, vitamin B12, and selenium. Here are some vitamins and minerals that may help with hair growth:

• Biotin: Biotin is a B vitamin that aids in cell growth and can help prevent hair loss. It can be found in foods like eggs, almonds, and sweet potatoes.

• Vitamin A: Vitamin A is important for normal cell growth and can contribute to hair loss when deficient. However, consuming too much vitamin A can also cause hair loss, so its important to regulate intake.

• Vitamin C: Vitamin C helps fight free radicals that can age hair and block growth. It is also important in creating collagen, which is used to make keratin, an important part of hair structure. Vitamin C can be found in foods like citrus fruits, strawberries, and bell peppers.

• Vitamin D: Vitamin D deficiency is associated with hair loss, but research supporting vitamin D supplementation for hair growth is limited. However, most people likely dont get enough vitamin D through diet alone, so its worth asking a healthcare professional if a supplement is necessary.

• Vitamin E: Vitamin E is an antioxidant that can help reduce oxidative stress, which has been linked to hair loss. It can be found in foods like sunflower seeds, spinach, and almonds.

• Iron: Iron is important for carrying oxygen to tissues throughout the body, including the hair follicles. Iron deficiency can contribute to hair loss, so its important to consume enough iron-rich foods like beef, lentils, and spinach.

• Zinc: Zinc helps boost overall immunity and is important for hair follicle health. It can be found in foods like oysters, beef, and spinach.

Its important to note that while vitamins and minerals can contribute to hair loss when deficient, over-supplementing can also cause harm. Its best to consult a doctor or healthcare professional before taking any supplements.
