Structure Of Hair & Scalp
hair is 80% protein, 15% water and small amounts of
lipids and inorganic materials.
growing hair follicle is richly supplied with blood
vessels, and the blood that bathes the follicle is the
transport medium for both essential and toxic elements.
As these elements reach hair follicles, they are incorporated
into the growing hair protein.
hair approaches the skin surface, it undergoes a hardening
process, or keratinization, and the elements accumulated
during its formation are sealed into the protein structure
of the hair. Because of the exposure of hair follicles
to the blood supply during growth, elemental concentrations
of the hair reflect concentrations in other body tissues.
Whereby we can divide types of hair into 3 : Oily Hair,
Normal Hair & Dry Hair.
cuticle is the outermost layer of the hair which provides
protection to the inner cortex layer. It is made up
of flattened, hard, horny cells. When the cuticle breaks
and dislodges at the end of the hair, the result is
split ends. Improper care and frequent use of harsh
chemicals on hair damage the cuticle.
cortex is the second layer. The qualitative properties
of strength, elasticity, pliability, direction and growth
pattern, width and the texture of hair depend on the
composition of the cortex. The cortex is composed of
fibers twisted together like a rope.
is the cortex which gives the hair its color. The presence
of the four natural pigments black, brown, yellow and
red are logged in the cortex in varying proportions,
and the air spaces in the cortex determine the color
and shade of hair. The excess black and deep brown pigment
is what gives oriental women the dark hair they possess.
Lastly, the medulla is the unimportant innermost layer
which is composed of soft keratin. Medulla is often
not present in some hair. Hair that lacks medulla is
no worse than hair that has medulla.
