Hair Loss from Breast Cancer Treatment

Yes, hair loss is a common side effect of certain breast cancer treatments, but it's important to understand when it happens and what to expect.

Which Treatments Cause Hair Loss?

Chemotherapy is the main treatment that causes hair loss (a condition called alopecia). According to the NCCN Guidelines for Patients: Invasive Breast Cancer, some chemotherapy drugs are more likely than others to cause hair loss, and the dosage you receive also affects how much hair you lose.

Hair loss from chemotherapy can occur all over your body—not just on your scalp. This includes eyebrows, eyelashes, and body hair.

Other treatments like surgery and radiation therapy typically do NOT cause hair loss.

When Does Hair Grow Back?

The good news: Hair loss from chemotherapy is usually temporary. According to NCCN Guidelines, most of the time your hair often regrows 3 to 6 months after treatment ends.

A few important things to know about regrowth:

Your hair may be a different shade or texture when it grows back
This is temporary—it typically returns to your normal hair characteristics over time

Can You Prevent Hair Loss?

There is one option that may help: Scalp cooling (also called scalp hypothermia) might help lessen hair loss in those receiving certain types of chemotherapy. This involves wearing a special cooling cap during your chemotherapy infusions. Ask your care team if this option is available and appropriate for your specific treatment plan.

Questions to Ask Your Oncology Team

Which chemotherapy drugs will I be receiving? (Some cause more hair loss than others)
Is scalp cooling an option for me?
When should I expect hair loss to begin?
What resources are available for wigs, scarves, or head coverings?
Are there support groups for patients dealing with hair loss?

Important Reminder

Your oncology team can provide personalized information about your specific treatment plan and what to expect. Many cancer centers have resources to help with appearance-related concerns during treatment, including wig services and support groups.
