Is It Normal to Lose Hair After Breast Cancer Surgery?

Yes, it’s very common. Hair loss is a well-known side effect linked primarily to chemotherapy, but it can also be influenced by the surgery and the stress your body undergoes during cancer treatment. Dr. Rinky Kapoor, Consultant Dermatologist and Cosmetic Dermatologist at The Esthetic Clinics, explains why hair loss happens:

• Chemotherapy involves the use of very powerful drugs with an aim of killing highly proliferating cancerous cells.
• But, unluckily, these drugs do have an effect on other fast-dividing cells, such as the hair follicles.
• This interruption leads to loss of hair not only in your hair, but it might affect the eyebrows, eyelashes and other body hair.
• Hair loss is unique to the type of chemotherapy drugs and how much they are taken:
• Some only lead to loss of hair.
• Others can result in complete baldness.

Dr Kapoor recommends consulting your healthcare provider to determine the various side effects that can be expected depending on the kind of treatment plan you might be on. Stress, hormonal changes, and surgery can also contribute to hair loss, as seen in Jessie J’s case, where the physical and emotional toll of her mastectomy played a role in her hair shedding.

What You Should Know About Hair Loss and Breast Cancer Treatment

The loss of hair usually commences a few weeks later in chemotherapy.

• It can attack every form of hair and at any part of the body.
• The growth of hair mostly begins after several months of the cessation of treatment but the hair may take a new form or colour during relapse.
• Scalp cooling caps may aid applicable hair loss, although this needs to be mentioned with your oncologist.
• The psychological effect of hair loss may be coped with the help of emotional support and counselling.

The fact that Jessie J is open about her hair loss helps to de-stigmatise this frequently occurring, sometimes alarming side-effect. It helps to inform other people under treatment that they are not alone and that losing their hair is a short-term process during treatment.
