Hair is flex i ble, because of the hydro gen bonds that give rise to ker -
a tin. Due to its elas tic hydro gen bonds, hair bends and is not eas i ly bro -
ken. But imag ine the oppo site! If ker a tin employed a dif fer ent chem i cal
bond, your hair would be very brit tle and hard as wood. As a result of
hydro gen bonds, such is never the case.
The bonds that give rise to hair mol e cu les have anoth er impor tant
fea ture. As hairs stretch, the sul fur bridg es that keep the mol e cu les
togeth er come to no harm. That is why how e ver hair is combed or
arranged, it can eas i ly reas sume its former shape. 47
Lightening or bleach ing the color of hair gen er al ly takes place by
impair ing the com pounds that give hair its color, usu al ly by solu tions
like hydro gen per ox ide that per mit the oxi di za tion of the mol e cu les.
When hydro gen per ox ide bleach es hair, a large num ber of sul fur bridg -
es form, which is why the hair becomes more brit tle and loses its elas -
tic i ty.
The sheen in hair aris es from its abil i ty to reflect light. Some hair
pro ducts and sham poos affect the hydro gen ions in the ker a tin mol e cu -
les and change the dis tri bu tion of their elec tri cal char ges. As a result, the
ker a tin mol e cu les and micro fibril nodes grip tight er to one anoth er and
improve their abil i ty to reflect light. These small molec u lar chan ges give
hair a bright er sheen. The way that hair becomes e more eas i ly man age -
a ble after the use of hair creams is again the result of var i ous chan ges at
the molec u lar level. In hair creams, there are ionic sub stan ces that attach
to ker a tin fibers and alter their elec tri cal char ges. This increas es the
mutu al ly repel lent force of hairs close ly aligned with one anoth er, mak -
ing it hard er for hairs to tan gle around each other and break.
The ker a tin mol e cule appears in many forms in objects you use in
daily life. Leather con sists almost entire ly of ker a tin mol e cu les. Wool,
silk, fish scale, fur and feath ers also con sist of ker a tin, as do claws and
nails. Yet these struc tures are com posed main ly of diag o nal bonds with
sul fur bridg es. This diag o nal bond ing shows that ker a tin has been more
