Chemotherapy-Related Hair Loss (Alopecia) in Children
What is chemotherapy-related hair loss?Hair loss is a common side effect of chemotherapy. It can affect the hair on the head, and also the eyebrows, eyelashes, and facial and pubic hair. Not all chemotherapy causes hair loss. And not all children lose hair in the same way. A child may lose his or her hair with a medicine and another child taking the same medicine may not. Your child's cancer specialist (oncologist) can tell you what to expect with your child's chemotherapy medicines.
What causes chemotherapy-related hair loss?Chemotherapy kills cells that grow fast, such as cancer. Hair also grows fast, so some chemotherapy may also damage the hair. The medicine harms the tissue around the root of the hair (hair follicle). This causes the hair to fall out.
What are the symptoms of chemotherapy-related hair loss?Hair loss from chemotherapy may start 2 or 3 or more weeks after your child's first or second chemotherapy treatment. Your child's hair may first begin to thin before falling out in larger amounts. Your child may lose hair only on the head. Or, he or she may lose hair on other parts of the body. Your child's scalp may also be sensitive, dry, and itchy. Hair usually begins to grow again about 2 to 3 months after your child's last treatment. The new hair may easily break at first. When hair grows back after chemotherapy, it may be a different color or texture.
How is chemotherapy-related hair loss diagnosed?
The healthcare provider will ask about your child's chemotherapy treatment and hair loss symptoms. He or she will examine your child’s scalp and hair. In some cases, the healthcare provider may do a pull test. He or she will grasp 20 to 60 hairs and pull gently but firmly. This is done to see how many hairs pull out. More than 10% of the hairs pulling out is a common sign of hair loss caused by chemotherapy. The roots of the hairs may be checked under a microscope. This is to see what stage of growth they are in.
How is chemotherapy-related hair loss treated?You will need to make sure your child's head is protected from sun and cold. You can apply sunscreen to your child's scalp or he or she can wear a hat or scarf. For dryness or itchiness, you can use a moisturizing shampoo and conditioner. You can also apply cream or lotion to your child's scalp.
What are possible complications of chemotherapy-related hair loss?Depending on your child's age and personality, hair loss can be very upsetting. A young child may not be bothered by hair loss. But a school age child or teen may be very upset.
