Does Melanoma treatment cause hair loss and when does it grow back

Hair Loss from Melanoma Treatment: What to Expect

Hair loss is a potential side effect of some melanoma treatments, but it depends on which treatment you receive. Let me break down what you should know.

Which Melanoma Treatments Can Cause Hair Loss

Radiation Therapy According to the NCCN Guidelines for Patients: Melanoma, radiation therapy can cause hair loss around the area where radiation is given. This is a localized effect—meaning hair loss typically only occurs in the specific region being treated, not all over your body.

The type of hair loss depends on the radiation dose and technique used:

• Intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT) are designed to target tumors precisely while limiting radiation to surrounding normal tissue, which may reduce hair loss risk
• Stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) deliver high doses in very focused beams, usually in just 1-5 sessions

Immunotherapy & Targeted Therapy The NCCN Guidelines note that immunotherapy drugs (like nivolumab, pembrolizumab, and ipilimumab) and targeted therapies (like dabrafenib/trametinib for BRAF mutations) are not typically listed as causing hair loss as a primary side effect, though individual responses vary.

When Does Hair Grow Back?

The NCCN Guidelines don't specify exact timelines for hair regrowth after melanoma treatment. However, here's what's generally true:

• After radiation: Hair typically begins regrowing 3-6 months after treatment ends, though this varies based on radiation dose
• Regrowth timeline: Full hair regrowth usually takes 6-12 months or longer
• Permanent vs. temporary: Lower radiation doses usually cause temporary hair loss, while very high doses may cause permanent hair loss in that area

Important Questions to Ask Your Care Team

Since hair loss depends heavily on YOUR specific treatment plan, ask your oncologist:

1. Which specific treatment am I receiving, and does it typically cause hair loss?
2. If I'm getting radiation, exactly which area will be treated? (This helps you understand where hair loss might occur)
3. What dose and technique will be used? (This affects hair loss risk)
4. Based on my specific situation, what timeline should I expect for hair regrowth?
5. Are there any ways to minimize hair loss risk, or products you recommend if it occurs?

Key Point

Hair loss from melanoma treatment is usually temporary and localized to the treatment area, especially with modern radiation techniques. Your oncologist can give you much more specific information based on your exact treatment plan, stage of melanoma, and location of your cancer.
