Hair Growth- Explained
Hair Structure
Hair is made up of several parts:
-
The cuticle is the outer layer which
protects the hair shaft. It is coated with sebum, which gives
the hair its shine. The cuticle is made of scale like cells that
resemble the shingles on a roof.
-
The cortex gives hair its strength,
elasticity, and texture.
-
The hair follicle is the part of
the skin that grows the hair.
-
Sebaceous glands produce the sebum
that coats the cuticle.
-
Melanin is the pigment in the cortex
which gives hair its color.
How Hair Grows:
Most people have about 100,000 hairs
on their head. Normal growth is about one quarter to one half inch
per month. Actually hair that grows one half inch per month is considered
fast growing. Every hair on your head will go through three phases:
growing, resting, and shedding.
-
The growing phase can last from 3
to 7 years.
-
The resting phase lasts about 2 to
4 weeks.
-
The shedding phase can last from
3 to 4 months. This shedding is the natural process that replaces
old hairs with new hairs. It is normal to lose about 50 to 80
hairs per day.
If you have ever wondered why your hair
will grow to a certain length then stop, it is because of your growing
phase. Your growing phase (or anagen) is a certain length of time.
This is something that we are born with, so there isn't much that
changes it. A person with a very long growing phase will grow longer
hair than a person with a shorter growing phase. Therefore, the anagen
phase actually determines the maximum length your hair will grow.
Hair vitamins can be used to make hair
grow faster, but it will not repair any damage done to your hair,
or prevent further damage. You must use treatments and other hair
care products to keep your hair from breaking. HairFinity vitamins
can make your hair grow up to twice as fast as normal.
