Using biotin for hair growth
Biotin, also referred to as vitamin B7 or vitamin H, is a water-soluble B-complex vitamin that plays a vital role in human metabolism. It functions as an essential coenzyme for five carboxylase enzymes, which are involved in key metabolic pathways—including the synthesis and breakdown of fatty acids, amino acids, and glucose. These biotin-dependent carboxylases catalyze reactions that incorporate bicarbonate into organic molecules, a step that is fundamental to energy production and nutrient processing [3].
Potential Benefits of Biotin [2]
- Improvement of hair thickness
- Improvement in hair density
- Hair growth
Causes of Biotin Deficiency [3]
- Alcohol consumption
- Pregnancy
- Medications (e.g., isotretinoin)
- Impaired intestinal absorption
- Prolonged use of antibiotics interrupting normal gut flora
Signs & Symptoms of Biotin Deficiency [1]
- Hair loss
- Dermatitis
- Ketolactic acidosis
- Organic aciduria
Foods that Contain Biotin [1]
- Nuts
- Legumes
- Whole grains
- Unpolished rice
- Egg yolk
When Biotin Isn’t Enough: Why a Lasting Solution Often Involves Hair Transplantation
While biotin supplementation may support hair health in cases of deficiency, it is not a guaranteed solution for all forms of hair loss. Individuals experiencing progressive or hereditary hair thinning should consult a qualified medical professional to determine the underlying cause. In many cases, especially with androgenetic alopecia, a hair transplant offers a more permanent and effective treatment option. Always speak with a medical doctor before starting any supplement regimen to ensure safety and suitability based on individual health needs.
