Graying of Hair
Causes of graying hair
The colour
of the hair depends on the presence of pigment granules in the cortex
of the hair. With age there is a gradual dilution of pigment in the
hair, so that in different hairs the full range of colours from normal
to white can be found.
Grey hair can
some times appear earlier. Rapid graying of hair may occur after severe
emotional stress. In certain internal diseases hair might gray early.
This is especially true of diseases of the thyroid gland and certain
types of anemia's. Localised patches of gray hair can appear in certain
areas. Perming, colouring and bleaching work to promote graying.
what can be done
The
usual and the most effective way of dealing with graying of hair is
dyeing it. There are several types of dyes available. The oxidative
dyes are the most versatile and the most frequently used. But dyeing
has its drawbacks- once you start dyeing it is seen to increase gray
hairs. Henna is also used because apart from its safety, it is a superb
conditioner. Having calcium pantothenate in the dose of 200 mg daily is
a good treatment.
