What to expect when undergoing cancer treatment

This week we wanted to discuss a serious topic here on the PHL blog, a topic which may have already affected some of our readers. 1 in 2 people will be diagnosed with some form of cancer in their lifetime here in the UK and sadly, someone dies every four minutes from the horrific disease.

We are faced with devastating statistics like this every day. We also recognise that going through treatment for cancer can be very traumatic. Along with other serious side effects, hair loss can cause a lot of distress. We want to discuss the different types of cancer treatments and what you can expect from your hair.

Generally, different types of cancer treatments can cause different types of hair loss. You may experience all over hair thinning, partial or patchy hair loss or in the worst case scenario, total hair loss. However, not all treatments will lead to your hair falling out.


We usually associate chemotherapy with hair loss. We think that if you need chemotherapy treatment it’s inevitable that your hair will begin to fall out. For some chemotherapy patients, this isn’t the case and hair will remains. However, the majority of people will find that they lose their hair.

After 2-3 weeks of chemotherapy treatment, you may notice your hair starting to fall out. Some may find that their eyelashes, eyebrows underarm and leg hair will also fall out. Although this can be a stressful experience, it is very unlikely that the hair loss will be permanent. Once you have finished your course of treatment, your hair will slowly begin to grow back. If your hair does not seem to be coming back once you have received all of your chemotherapy treatment, this may be due to high dosages of treatment.


Radiotherapy can also cause your hair to fall out. Hair loss is unlikely to fall out in all places like chemotherapy, however it is very likely that it will fall out in the treatment areas. Unfortunately, it is not guaranteed that your hair will regrow after radiotherapy treatment, as many different factors affect the likelihood. For example….

- Type of radiotherapy treatment and the dose

- The number of treatments

It may take several months for your hair to grow back in the affected areas, so do not despair. Additionally, your hair may grow back a different colour than it was previously.


If hair is present in the area which requires operating on, it is more than likely that the area will be shaved in order to operate. Once you have had the operation and begin to recover, your hair will grow back.

Hormonal therapies

If you have undergone hormone therapy to treat your cancer, it may affect the quality of your hair. Hair could fall out completely, but many people tend to find that their hair becomes thinner, more fine or brittle. Once you have received your full course of treatment, your hair will begin to grow back.

As we have already stated, in most cases, depending on the treatment, your hair will grow back in time. No treatment is completely necessary in order to grow your hair, but PHL products can assist hair regrowth. If you think your hair may be thinner than it previously was or not as healthy, PHL products can help.
