As the individual asking this question will be aware from their Oncologist; Radiotherapy rarely affects the hair, other than slightly altering the texture. However Chemotherapy often causes the hair to fall out. Hair loss also depends on other factors such as:
The type of drug or combination of drugs you are taking, the dose, your individual sensitivity to the drug, your drug treatment in the past.
In some cases a “cold cap” can be worn during radiation, which can sometimes prevent hair loss, but not always. In most cases after Chemotherapy the hair will grow back. The time in which hair takes to regrow varies from person to person. Some people find that their hair grows back curly when before it may have been straight or vice versa! Others find that the hair is a totally different colour.
At Sussex Trichology, we can help 3 months after a person has finished their cancer treatment. We can ensure that correct blood testing is carried out and offer the support and advise needed until the hair is nursed back to its former glory.
