Hair loss can be caused by various factors, including aging, genetics, hormones, chronic illness, and vitamin deficiencies. The following vitamin deficiencies have been associated with hair loss:
-
Vitamin B2 (riboflavin): A deficiency in this vitamin has been linked to hair loss.
-
Biotin (Vitamin B7): A deficiency in biotin can cause hair loss and brittle nails.
-
Folate (Vitamin B9): A deficiency in folate can lead to hair loss.
-
Vitamin B12: A deficiency in vitamin B12 has been associated with hair loss.
-
Iron: Iron deficiency is one of the most common causes of hair loss, especially among women with heavy periods and vegans. Low serum ferritin levels have been debated as a nutritional deficiency triggering hair loss.
-
Vitamin D: Some research suggests that symptoms of a common form of alopecia may be more severe in people with low levels of vitamin D. Vitamin D receptors are found in keratinocytes, the skin cells that process a protein in hair called keratin. When vitamin D levels are low, it disturbs the hair follicle growth.
-
Zinc: A deficiency in zinc can lead to hair loss.
It is important to note that while vitamin deficiencies can cause hair loss, they are not the only cause. Other factors such as genetics, hormones, and chronic illness can also contribute to hair loss. If you are experiencing hair loss, it is best to consult with a healthcare provider to determine the underlying cause and appropriate treatment.
