Detailed explanation-1: -This is because the keratin in our hair contains large amounts of cysteine, a sulfur-containing amino acid. * (Hooves and nails also contain keratin, which explains why real tortoise shells smell like hair when lit on fire.) The smell of burnt hair can cling to the nostrils for days.

Detailed explanation-2: -The sulfur atoms are now free to chemically combine with other elements present in the protein and air, such as oxygen and hydrogen. The volatile sulfur compounds formed as a result is what’s responsible for the fetid odor of burning hair.

Detailed explanation-3: -Your shampoo might be responsible. In few shampoos, especially anti-dandruff shampoos, we find a compound named selenium sulphide. This compound has antifungal properties that help cleanse the scalp. But it also has a residual Sulphur odour, which is the typical smell of rotten eggs.
