What is Chemotherapy?

Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. The drugs can be given in different ways, such as through injection, pill, or intravenous (IV) drip. Chemotherapy drugs are designed to target rapidly dividing cells, which includes cancer cells. However, they can also affect healthy cells in the body, such as those in the hair follicles.

How Does Chemotherapy Work?

Chemotherapy works by targeting rapidly dividing cells in the body. Cancer cells divide quickly, which allows them to grow and spread throughout the body. Chemotherapy drugs are designed to target these cells and stop them from dividing. However, healthy cells in the body also divide quickly, such as those in the hair follicles, which can lead to hair loss.

Why Does Hair Fall During Chemotherapy?

Hair loss is a common side effect of chemotherapy. The drugs used in chemotherapy target rapidly dividing cells, including those in the hair follicles. This can lead to hair falling out from the scalp, as well as other areas of the body, such as the eyebrows and eyelashes. Hair loss can begin as early as a few weeks after starting chemotherapy and may continue throughout the treatment.

It's important to note that not all chemotherapy drugs cause hair loss. The likelihood of experiencing hair loss during chemotherapy depends on the type of drugs used and the dose given. Some drugs may cause only mild hair thinning, while others may cause complete hair loss.

How to Manage Hair Fall During Chemotherapy

While hair loss during chemotherapy is unavoidable for many people, there are some things you can do to manage it:

  1. Consider cutting your hair short before starting chemotherapy. This can make hair loss less noticeable.
  2. Use a gentle shampoo and conditioner that is designed for thinning hair.
  3. Avoid using heated styling tools, such as hair dryers, curling irons, and flat irons. These can further damage hair that is already fragile.
  4. Consider wearing a wig, scarf, or hat to cover your head.
  5. Be gentle with your hair when brushing or combing it. Use a wide-toothed comb or brush and avoid pulling or tugging on it.

Tips for Hair Care During Chemotherapy

In addition to managing hair loss, it's important to take care of any hair that remains during chemotherapy:

  1. Wash your hair with lukewarm water and a gentle shampoo. Avoid using hot water, as this can further damage hair that is already fragile.
  2. Avoid using hair styling products that contain harsh chemicals, such as hair spray and gel.
  3. Consider using a satin or silk pillowcase, as these are gentler on hair than cotton pillowcases.
  4. Protect your hair from the sun by wearing a hat or scarf when you're outside.
  5. Eat a healthy diet that is rich in protein, vitamins, and minerals. This can help support the growth of healthy hair.
