A member of the B complex family of vitamins, vitamin H, is sometimes called biotin. All B vitamins aid in the body's conversion of glucose, which creates energy from food (carbohydrates). The body needs these B vitamins, commonly known as B complex vitamins, to help digest protein and lipids. Nonetheless, the body does not store biotin because, like all B vitamins, it is soluble in water. Biotin is crucial in maintaining healthy hair, skin, and nails and has garnered attention for its potential benefits.
What do the benefits of biotin for hair include?
There are 5 most popular benefits of biotin for hair include the following:
1. Promotes Hair Growth
Biotin is thought to promote hair growth by supporting the production of keratin. This protein forms the structure of hair strands as studies have suggested that biotin supplementation may promote hair growth in individuals with hair loss or thinning. For example, a randomized, placebo-controlled trial published in the Journal of Clinical and Aesthetic Dermatology found that daily supplementation with biotin significantly increased hair growth in women with thinning hair over 90 days1.
2. Strengthens Hair Follicles
Biotin plays a vital role in maintaining the health of hair follicles, the tiny structures from which hair grows. Research suggests that biotin deficiency can lead to weakened hair follicles and hair loss; along those lines, a study found that biotin supplementation improved hair quality and strength in individuals with brittle nails and hair. By supporting the structural integrity of hair follicles, biotin helps prevent breakage and hair loss1.
3. Enhances Hair Thickness and Volume
In addition to promoting hair growth, biotin may also enhance hair thickness and volume; to further explain, a study investigated the effects of biotin supplementation on hair diameter in women with thinning hair. The researchers found that biotin supplementation led to a significant increase in hair diameter, resulting in thicker and fuller-looking hair1.
4. Supports Scalp Health
Biotin plays a crucial role in maintaining a healthy scalp environment, which is essential for promoting optimal hair growth. Research suggests that biotin deficiency may contribute to scalp conditions like seborrheic dermatitis and dandruff as one study reported. By supporting scalp health, biotin helps create a favorable environment for hair growth1.
5. Prevents Premature Graying
While the evidence is limited, some studies suggest that biotin may play a role in preventing premature graying of hair. Biotin is involved in the production of melanin, the pigment responsible for hair color. While more research is needed, ensuring adequate biotin intake may help maintain hair color and delay the onset of premature graying.
