Our hair grows from indentations in the skin called follicles. There are over 100,000 hairs on the average head and they each have a continual growing, resting and falling cycle. When we are healthy, about 90% of our hair is in the growing phase.
Cancer treatments can affect your hair’s normal phases of hair growth. Some treatments may make your hair fall out completely. This may be from your head and other parts of your body. This is usually temporary. Other treatments can cause permanent hair loss in specific areas of your body. Sometimes, complete hair loss may not happen, but your hair can become thinner and more brittle.
