The normal scalp
contains approximately 100,000 hairs. They are constantly growing, with
old hairs falling out and being replaced by new ones. Some cancer
treatments will cause some people to lose some or all of their hair
(alopecia). For example, with chemotherapy, drugs travel throughout the
body to kill cancer cells, and some of these drugs damage hair
follicles, causing the hair to fall out.
Hair loss is highly
variable. Some people experience it and others do not, even when they
are taking the same drugs. While some drugs can cause hair loss on the
scalp and elsewhere on the body, others can cause only the loss of head
hair. If hair loss does occur, it usually begins within 2 weeks of
starting chemotherapy and gets worse 1 to 2 months after the start of
therapy. It may come out in clumps that appear on the pillow in the
morning or while shampooing or brushing your hair. Hair re-growth often
begins even before therapy is completed.
Like chemotherapy,
radiation therapy to the head often causes scalp hair loss. Unlike hair
lost because of chemotherapy, however, hair lost as a result of
radiation therapy to the head may not grow back naturally.
It is
normal for someone undergoing cancer treatment to feel distressed about
hair loss. But it can help to understand why it happens, to know that
hair will probably grow back, and to take some steps to minimize the
problem.
What to Do
Choose a
wig or toupee before treatment begins or at the very start of treatment,
before hair loss begins, so that hair color and texture can be matched
Get
a prescription for the wig from the doctor, because the cost is often
covered by insurance
Obtain a list of wig shops in your area
from the doctor, nurse, or the Yellow Pages
If you have long
hair, consider getting a stylish short cut and then having a beautiful
wig made from your own hair
Try on different wigs until you
find one that you really like
Consider buying 2 wigs, 1 for
everyday wear and 1 for special occasions
Before you need to
wear the wig, be gentle when brushing and shampooing your own hair
Wear
a hat or scarf outdoors in cold weather to prevent loss of body heat
Avoid
too much brushing or pulling of hair, and avoid heating it with a hair
dryer, electric rollers, or curling iron to help reduce hair loss and
damage
Use a sunscreen, sunblock, or hat to protect your scalp
from the sun
Choose turbans or scarves as alternatives to wigs
Do Not
Wait to go shopping for a wig; try
to have it ready when you need it
Forget your hair will grow
back and that a good wig looks very natural
