lack of Vitamin B7 causing hair loss and skin issues
Biotin deficiency, also known as Vitamin B7 deficiency, occurs when the body lacks sufficient biotin, a water-soluble B-vitamin essential for metabolizing fats, carbohydrates, and proteins. Symptoms can include hair loss, skin rashes, brittle nails, and neurological issues such as depression and lethargy. This condition can result from inadequate dietary intake, genetic disorders affecting biotin metabolism, or prolonged consumption of raw egg whites, which contain avidin, a protein that binds biotin and prevents its absorption.
