Eggs are rich in biotin, a B vitamin essential for hair growth and overall scalp health. People ask me about biotin for hair health all the time — usually, they’ve heard about it on a shampoo commercial or read a magazine article that recommended biotin supplements. Because our bodies make their own biotin in the intestines, and it is plentiful in many common foods, deficiency is very rare. But in those few cases in which people are very ill and don’t have use of their intestines, biotin deficiency causes hair loss. So yes, biotin is important for hair health, but you don’t need to take supplements. Just eat a balanced diet that includes some high-biotin foods: eggs, peanuts, almonds, wheat bran, salmon, avocados, and low-fat cheese.
