CHEMOTHERAPY AND HAIR LOSS

CANCER. The word alone creates fear and confusion. Patients face not only the uncertainty of their disease, but also the anxiety of treatment—particularly hair loss.

This article provides facts about the relationship between chemotherapy, radiation therapy and hair loss. Its aim is to provide you with the information you need, using non-medical language, to understand what is happening to your hair, and why.

Chemotherapy consists of the administration of drugs that destroy rapidly reproducing cancer cells.

Cancer cells are some of the most rapidly reproducing cells in the body, but other cells, such as those
which contribute to the formation of hair shafts and nails, are also rapidly reproducing. Unfortunately, while chemotherapy drugs preferentially destroy cancer cells, the drugs also can destroy those cells responsible for normal growth of hair and nails. Cancer patients sometimes shed the hair and nails during treatment. Chemotherapy drugs are poisonous to the cells of the hair root responsible for hair shaft formation. Usually, the hair is lost rapidly in large quantities during treatment.

No hair growth stimulants, shampoos, conditioners, or other cosmetic treatments can prevent or retard chemotherapy related hair loss.  The good news, however, is that once chemotherapy is completed, the hair usually grows back.  This “grow back” period can take anywhere from 12 to 18 months.

WHAT ABOUT INSURANCE?

• Your insurance may cover the cost of a medical wig or hair prosthesis (prosthetic hair system). Be sure to check with your insurance agent to find out about your exact coverage and benefits.

Hair Growth

Hair grows from the root, from the hair follicle, where a constant process of cell division occurs. Amino acids taken from blood feeding the follicle join with dividing cells, resulting in cell chains. Eventually these cell chains link up with one another, resulting in a long fiber. At this point, the nucleus of the original cell is dead, and the amino acids have formed into a hard keratin.
Keratin is a protein, and it is the substance our hair and nails are made from. It is a lifeless substance that results from the “pushing” of newly forming cells in the follicle. As the keratin protein is pushed out, our hair grows from the root. The growth of our hair follows a cyclical pattern that is one of the body’s most active “growing” processes: building shafts of hair for a period of time, and then resting.

Anti-cancer Drugs

Cancer is a condition of uncontrolled cell growth. Anti-cancer drug administration aims to reduce or stop this process. However, anti-cancer drugs act on both normal and cancerous cells, and are most likely to destroy cells that reproduce quickly. Hair follicles divide rapidly, which is why they are affected by chemotherapy. At any one time, about 85% of scalp hair follicles are reproducing.
Because a variety of drugs are used for chemotherapy treatment, hair loss depends upon the type prescribed and the dosage. Not all chemotherapy causes hair loss and, except in rare instances, hair loss is temporary. When treatment is completed, the hair follicles will resume processing amino acids from your blood and creating new hair for you.

Radiation Therapy

Radiation therapy employs high-energy radiation to inhibit the growth and division of cancer cells. It destroys all cells’ ability to grow and multiply in the area of application; however, cancer cells are more sensitive to radiation than normal cells. If treatment is applied as a cancer cell is about to reproduce it will prevent the cell from doing so, and the cell will die. Still, radiation therapy can sometimes affect normal tissue, causing side effects. One possible result of treatments to the head and neck is hair loss. Some or all of your hair in the area being treated may be lost. But, in most cases, hair growth will resume at the end of the treatment cycle.

Plan Ahead for Your Treatment

  • Assume you will lose all of your hair when you begin chemotherapy treatment. By doing so your advance planning will assist you considerably. (Custom made wigs and hair prosthetics may take from 6 weeks to 4 months to be delivered and made for you.)
  • Your first wig or hair prosthesis should duplicate your hair as closely as possible. (Be conservative in color, length, thickness and style.)
  • In chemotherapy related hair loss avoid the following: weaves, hair extensions, hair integration and hair intensifiers. You will require a full prosthesis and not a partial hairpiece.

Hair Loss Alternatives

There are several options for dealing with hair loss once it occurs. You may choose to cover your head with a hat, scarf or turban. Or, you may choose to replace your hair either with a medical wig or a prosthetic hair system.

If you choose to replace your hair, you’ll be happy to know that fake-looking wigs are a thing of the past. New technologies have made both human hair wigs and synthetic wigs appear highly realistic because they can be fitted to the shape of your head. Human hair wigs are typically more expensive and require more maintenance. Synthetic wigs are less expensive (although some special models are more expensive), and are easier to style and wash. Synthetic wigs also dry more quickly, and require less care.
