Hair Loss

Hair loss from chemotherapy and radiation.

Many cancer treatments affect hair follicles. Knowing what to expect — and planning ahead — can make this period a little easier, with discreet, natural-looking options to help you feel like yourself.

Understanding it

About chemotherapy and radiation

Many chemotherapy medicines act on rapidly dividing cells, which include the cells of the hair follicle. Depending on the treatment, hair may thin or fall out, usually beginning a few weeks after the first sessions. Not every treatment causes hair loss; your oncology team can tell you what to expect.

After chemotherapy ends, hair commonly begins to regrow, and its texture or color may be different at first. Radiation therapy affects hair only in the area being treated; depending on the dose, hair loss in that area may be temporary or permanent.

Common causes

  • Chemotherapy medicines that affect dividing cells
  • Radiation therapy to the head or scalp
  • Some targeted and hormonal therapies, which may cause thinning

Signs and symptoms

What you may notice.

  • Thinning or shedding a few weeks after starting treatment
  • A sensitive or tender scalp
  • Loss of eyebrows, eyelashes or body hair with some treatments
  • Regrowth with a different texture or color after treatment

Managing it

Approaches that may help.

Plan ahead

Many people prefer to explore options before or early in treatment, so there is time to choose calmly.

Ask about scalp cooling

For some chemotherapy regimens, scalp cooling during treatment may reduce hair loss. Your oncology team can tell you whether it suits your treatment.

Care for the scalp

Follow your oncology team's advice and use gentle products on a sensitive scalp.

Natural-looking coverage

A custom cranial prosthesis can restore your appearance discreetly during and after treatment.

When to see a physician

Please follow the advice of your oncology team about scalp care during treatment. When medical care is involved, we collaborate with your physician.

Frequently asked questions

Your questions, answered.

We do not diagnose medical conditions; when medical care is involved, we collaborate with your physician.

Will my hair grow back after chemotherapy?

Hair commonly regrows after chemotherapy ends, though timing and texture vary. After radiation, regrowth depends on the area and dose treated.

When should I plan a consultation?

Many clients prefer to meet us before or early in treatment, so there is time to plan. A private consultation carries no obligation.

Is a CNC® only for permanent hair loss?

No. CNC® may be considered for hair loss related to chemotherapy or other medical treatments, whether temporary or long-term.

Can insurance help cover a cranial prosthesis?

For clients whose cranial prosthesis has been prescribed by a physician for medically related hair loss, we offer a complimentary insurance benefits check. Coverage depends on each client's individual policy, and reimbursement cannot be guaranteed.
