Common Questions About Hair Loss During Cancer Treatment

Although this is deeply associated with cancer treatment, not all people lose their hair

Common Questions About Hair Loss During Cancer Treatment

Hair loss is a possible adverse reaction to some cancer treatment procedures. Check the answers to some of the most frequently asked questions about it.

Does hair always fall during cancer treatment?

No, not always. Induced alopecia, the medical name for this situation, can be total or partial. The first hair strands usually start to fall out in a few days or weeks after the first treatment sessions. The head is not the only area affected, as hair may fall from other parts as well, such as eyebrows, arms and the pubic region.2,3

Hair loss during treatment depends on several factors, such as the type of therapy required, medication doses used in some of these therapies, and physical characteristics, such as genetic tendency to hair loss and health issues.2-4 Among treatments that may lead to it are:3

  • Chemotherapy with some categories of specific drugs, such as topoisomerase inhibitors, antimetabolites and antimicrotubule agents;
  • Radiotherapy;
  • Targeted therapy.

Is there any way to prevent hair loss during treatment?

There are therapies that try to slow down the process. The main one is scalp cooling, a technique in which people use a thermal cap that decreases the scalp temperature and affects blood circulation in the area, preventing the substances in the drugs from reaching the hair.1

Am I allowed to do cosmetic procedures in my hair during treatment?

Experts recommend avoiding any aesthetic procedure that may somehow hurt the scalp during cancer treatment because it will be more sensitive and susceptible to injuries. Ideally, you should refrain from: 2

  • Using the hair dryer at high temperatures;
  • Bleaching or dying your hair;
  • Using a straightening flat iron or curling iron too close to the scalp;
  • Doing procedures that involve using strong chemicals.

What happens to hair after cancer treatment?

Hair loss is temporary. It will naturally grow again between three and six months after treatment ends. It may be a different texture or even color at first sometimes, but this is also temporary. It will go back to its natural state after some time.1-,3

Hair loss still greatly impacts cancer patients psychologically nowadays. Any measures that may reduce chemotherapy side effects are expected to lead to more quality of life. Research shows that scalp cooling is currently the only safe and effective option available for reducing and even preventing hair loss. Talk to your doctor about the possibility of performing this or another known and safe therapy if you want.1
