Have you ever burnt a strand of your own hair before? I did. By accident. But I would like very much not to talk about it. It smelt terrible! Something like being locked in a room with a gorilla with a bad case of the runs and he cuts the cheese right in front of your face which is tied to his rear-end.

This is because of DISULPHIDE BONDS in your hair. Yes. -highlighthighlight- The smell we detect in farts is generated by Hydrogen Sulphide. The very thing that thermophillic bacteria in sea vents emit deep under water. These disulphide bonds are the forces that hold keratin (a protein) in your hair tightly together so that it would have structural and tensile strength. (High tensile strength means that you can support about 300 people by your hair alone!) When you burn your hair, the combustion causes the disulphide bonds to break and the sulfydyl groups to be released as hydrogen sulphide. And as such, we should never ever burn our hair for fun. Because it STINKS.
-bows- Thank you. Haha.
On the side note, keratin is also strengthened by the present of small amino acids like glycine and alanine to ensure the tight-packing of all the tropocollagen strands into a large macrofibril (: That's why cavemen drag their wives around by their hair.
Talking about nice hair, I must now tell the whole world,
Because she's a loving, caring friend who has my well-being at heart. (: <3
