why do people with cancer have no hair

Hair loss occurs because chemotherapy targets all rapidly dividing cells healthy cells as well as cancer cells. Hair follicles, the structures in the skin filled with tiny blood vessels that make hair, are some of the fastest-growing cells in the body. If you're not in cancer treatment, your hair follicles divide every 23 to 72 hours. But as the chemo does its work against cancer cells, it also destroys hair cells. Within a few weeks of starting chemo, you may lose some or all of your hair. If you are having, your hair loss may be gradual or dramatic: clumps in your hairbrush, handfuls in the tub drain or on your pillow. Whichever way it happens, it's startling and depressing, and you'll need a lot of support during this time. Some chemotherapy drugs affect only the hair on your head.

Others cause the loss of eyebrows and eyelashes, pubic hair, and hair on your legs, arms, or underarms. The extent of hair loss depends on which drugs or other treatments are used, and for how long. The
all produce different reactions. The timing of your treatments will also affect hair loss. Some types of chemotherapy are given weekly and in small doses, and this minimizes hair loss. Other treatments are scheduled every three to four weeks in higher doses, and may be more likely to cause more hair loss. Adriamycin (the A in CAF chemo treatment) causes complete hair loss on the head, usually during the first few weeks of treatment. Some women also lose eyelashes and eyebrows. Methotrexate (the M in CMF chemo treatment) thins hair in some people but not others.

And it's rare to have complete hair loss from methotrexate. Cytoxan and 5-fluorouracil cause minimal hair loss in most women, but some may lose a great deal. Taxol usually causes complete hair loss, including head, brows, lashes, pubic area, legs, and arms. Other types of breast cancer treatments may also cause hair loss. For example, Radiation only causes hair loss on the particular part of the body treated. If radiation is used to treat the breast, there is no hair loss on your head. But there might be loss of hair around the nipple, for women who have hair in that location. Radiation to the brain, used to treat metastatic cancer in the brain, usually causes complete hair loss on the head.

Tamoxifen may cause some thinning of your hair, but not baldness. No matter how forewarned you are and how ready you think you are, it's always a terrible shock when your hair falls out. Because scalp cooling devices aren't covered by insurance, the researchers were hoping to show the psychological effects for women experiencing hair loss through quality of life data. In the Paxman study, there was no difference in quality of life for those who used scalp cooling devices versus those who did not. In the DigniCap study, those who used the scalp cooling devices felt less upset about losing their hair and experienced less of a negative effect regarding feelings about their physical attractiveness and femininity.
