To understand hair loss it is important that you understand the hair growth cycle. A normal cycle of hair growth will last from two to six years.
Each hair on your head will grow only about one half
inch each month during the growth phase. Approximately, ninety percent
of your hair is growing at one time. The other ten percent of your hair
is in the resting phase. When two or three months have passed the hair
that is in the resting phase will start to fall out and new hair will
grow in it's place. Your hair will continue through this cycle several
hundred times unless something happens to interrupt it. That is why if
you start to experience hair loss, hormones should be considered as one
of the causes.
Have you ever noticed that a pregnant woman's hair looks thick and
luxurious? The reason for this is that specific hormones that are
abundant during pregnancy will interrupt the normal hair loss and growth
cycle. Hair will not fall out during pregnancy, but you may experience
hair loss three months after the birth of a baby. This is because the
hormones levels have returned to normal and the hair growth cycle has
resumed.
When you notice hair loss, hormones could be the culprit. An under
active or over active thyroid gland can cause you to lose your hair. The
function of the thyroid gland is to take the iodine found in the food
that you eat and turn it into thyroid hormones. These thyroid hormones
regulate the body's metabolism. When these hormones are out of balance
due to a thyroid gland that does not work properly hair loss may be one
of the symptoms. Once you regulate the hormone production from the
thyroid gland, the hair loss will stop.
Excessive hair loss can be caused by many things. For example, if you
have had major surgery in the past three months you may notice your hair
starting to fall out. This is due to the physical stress of the surgery.
Even though your body is healed, you have to remember that the hair
cycle is delayed so the hair follicles that stopped growing at the time
of the surgery will not fall out until three months after the event.
This will hold true of any traumatic or life altering event that caused
you severe stress.
If you take no medications, are in reasonably good health and start to
experience hair loss, hormones should be considered as one of the
reasons that your hair is falling out. Hormones are what keeps all our
bodies running on an even keel and when these hormones get out of
balance our hair will let us know.
