Why Does Burnt Hair Smell So Bad?

In an unfortunate turn of events, you reach over a candle and singe the hair on your arm. 
Or perhaps your curling iron starts to smoke as it burns a section of the hair on your head 
(as it did in the case of this young girl, whose hair trouble went viral on YouTube last year). 
Once youre over the initial shock of the unexpected fire hazard, what lingers is the distinct, 
sharp odor of burnt hair. Thanks to reader MuradResurgence, the weasel decided to explore the cause of this funky phenomenon.

The Chemistry of Burnt Hair
Human hair is made up of keratin, a fibrous structural protein. Keratin is also a main component 
in skin and nails. This particular type of keratin is alpha keratin or a-keratin, 
and it contains significant amounts of cysteine, which acts as a cross link for 
keratins polypeptide chains. This cysteine essentially works as the glue that holds 
the structural elements of keratin together. As a  sulfhydryl group, 
or an amino acid containing sulfur, cysteine is ultimately to blame for the foul smell of burnt hair.
Sulfur: The Stinky Element
There are many well-known smells of the world that can blame sulfur for their notoriety. 
The stench of odorized natural gas (which without the addition sulfide to aid in its detection 
is naturally odorless), skunk spray, and garlic can all blame their sulfuric compounds. 
Perhaps the most famous form of odorous sulfur is that which is attributed to rotting eggs. 
But give sulfur a break. Not all forms of sulfur stink. With enough oxygen, 
sulfur can take the form of sulfate, which is generally not as offensive as 
its hydrogen sulfide counterpart, the unfortunately stinky variety found in hair.
