What is a vitamin deficiency?
Vitamin sickness is a condition that occurs when the body is unable to obtain sufficient amounts of certain vitamins to function properly, and micronutrients needed for reactions.
Vitamin deficiencies that cause hair loss:
Vitamin deficiency is a modifiable risk factor for alopecia (hair loss). This means that treatment with this agent can treat or prevent hair loss.
Vitamin B7 (biotin) deficiency
Biotin, also known as vitamin B7, is a water-soluble complex vitamin that is well known for its hair growth benefits.
This hair vitamin converts certain amino acids into keratin. Keratin is the primary structural protein that the body uses to build the structure of hair and nails, and thanks to the formation of keratin, biotin makes hair stronger, healthier, and less prone to breakage and hair loss. This protein also promotes the growth of healthy hair follicles and increases hair elasticity.
Vitamin D deficiency
Vitamin D is essential for healthy hair growth, and this fat-soluble vitamin helps activate genes involved in the growth of hair follicles. It enhances density and fullness. A review of the scientific literature shows how vitamin D helps hair regrowth.
Vitamin B12 deficiency
Vitamin B12 promotes hair growth by helping to form red blood cells that carry oxygen to the body, including the scalp and hair follicles.
Vitamin C deficiency
Vitamin C, also known as ascorbic acid, mainly improves hair growth. Without enough vitamin C, hair becomes brittle and prone to breakage, and dandruff is more likely to occur, causing hair loss.
Vitamin E deficiency
Vitamin E is an antioxidant that helps protect hair follicles from damage, and it also helps direct blood circulation to the scalp, promoting healthy hair growth.
Vitamin A deficiency
Vitamin A deficiency leads to weak hair follicles and brittleness, which leads to hair loss, and it also causes dryness and flaking of the scalp, which leads to increased hair loss.
