Biotin (vitamin B7 or vitamin H) is a water-soluble vitamin that plays an important role in maintaining healthy hair, nails, and skin. Below is a more detailed explanation of how biotin affects hair health.
Role of Biotin
Promotes keratin production
- Hair is mainly made of a protein called keratin, and biotin is an important nutrient that helps produce this keratin. Lack of keratin can cause hair to become thin, weak, and prone to breakage. Adequate biotin intake helps hair grow strong and healthy.
Supports cellular metabolism
- Biotin is involved in the metabolism of lipids, proteins, and carbohydrates. This allows hair root cells to efficiently utilize the energy needed for growth. Active growth of hair root cells promotes the hair growth cycle and facilitates the growth of healthy hair.
Improved hair strength
- Biotin increases hair strength, making hair more resistant to damage. This makes hair more resistant to everyday damage (e.g., from brushing and styling).
Maintain healthy scalp
- Biotin also supports sebaceous gland function and keeps the scalp from drying out. Moderate sebum secretion contributes to the maintenance of the scalp’s moisture and barrier function, which in turn promotes hair health.
Biotin deficiency and its effect on hair
A deficiency of biotin can have a variety of adverse effects on hair. In particular, hair may fall out easily, become thin and weak. The following are common symptoms of biotin deficiency
- Hair loss (especially on the top of the head)
- thinning of the hair
- Dry hair and dandruff
- Increased susceptibility to nail breakage
Sources of Biotin
Biotin can be obtained naturally from foods. Foods rich in biotin include
- egg yolk
- Nuts (almonds, walnuts, etc.)
- Meat (liver, chicken)
- Fish (salmon, tuna)
- Soybeans and legumes
- whole grain
Biotin supplements are also available commercially and can be used to maintain healthy hair and nails.
Conclusion
Biotin is important for maintaining healthy hair because it aids in keratin production and promotes hair strength and growth.Adequate biotin intake helps prevent hair damage and hair loss.
