All the hair you’ll ever have
on your head is determined at birth. That’s because hair grows
from a root in your scalp and the number of roots cannot be
changed.
The life span of a hair is about 7 years. You lose about
100 hairs every day from this life cycle. Growth will slow down
as it nears the end of its lifecycle. When the hair falls out, a replacement begins to grow. Therefore, your head is a constant mix of
hairs of different ages. You can help make a shaft grow longer by
taking good care of each shaft – easy brushing, mild shampoos,
gentle scalp massage, limiting coloring and perms.
Why you lose
hair: 1) Genes: If hair loss runs in the family, there’s not much you
can do about it.
2) Hormone imbalance: For women, all phases of the
pregnancy cycle and pregnancy prevention may have hair loss as a side
affect, but it’ll grow back. However, menopause also results in loss of
hair but it will not grow back.
3) Medical problem: thyroid
conditions or autoimmune diseases like lupus usually cause hair
loss. Your doctor can give you a blood test to tell if you have a
problem.
4) Medicines: lots of medicines can make you loses you
hair, like chemotherapy or thyroid, blood pressure,
anti-depressant, and anti-seizure meds.
5) Nutritional
deficiencies: too much dieting or a bad diet will affect your
hair.
6) Stress.
7) Too tight hairstyles: keeping your hair
in tight buns, pony tails, braids, or extensions put a lot of
pressure on the hair, especially at the front hairline. Give your hair a
break once in awhile by letting it hang freely.
8)
Alopecia is the loss or thinning of hair for an unknown reason. The
current theory is that alopecia is caused by reaction in your
immune system. It usually starts as a small, round bald patch.
Most of your hair will grow back in about a year. Here are some treatments you can get from your doctor:
Cortisone – a steroid
you can apply as a cream on your scalp, have it injected into your scalp or injected in a muscle, or in the form of
prednisone. Rogaine or Propecia, brand-name applications. Contact
irritants – your doctor will apply a chemical to set up an allergic
reaction. The theory is that by creating an allergy, you
interfere with the immune system enough to whack it back in sync
so you hair will grow back.
