Chemo Caps vs. Hoods: Headwear for Cancer Treatment

The term "chemo hood" is not standard in oncology practice. The correct term is chemo cap (or cold cap for scalp cooling).

Chemo Cap (Standard)

• Purpose: Provides warmth, comfort, and dignity during hair loss (alopecia) from chemotherapy. Protects sensitive scalp from temperature changes and sun.
• Materials: Soft, breathable fabrics (bamboo, cotton, silk, fleece). Seamless designs minimize irritation.
• Styles: Turbans, beanies, pre-tied scarves, sleep caps.
• Timing: Worn during and after infusion, at home, outdoors.

Cold Cap (Scalp Cooling System)

• Purpose: Reduces chemotherapy-induced alopecia by vasoconstricting scalp vessels, limiting chemo drug delivery to hair follicles.
• Types: Gel-filled caps (frozen to -30°C, changed every 20–30 min) or machine-controlled systems (DigniCap, Paxman) circulating coolant.
• Efficacy: 50–60% retain significant hair (varies by regimen, fit, hair type).
• Use: Worn 30 min before, during, and 60–90 min after infusion.

Why Not "Hood"?

"Hood" implies a attached covering (like a hoodie) which is impractical for IV access, temperature monitoring, and patient comfort during long infusions. Caps are adjustable, removable, and compatible with clinical monitoring.

Recommendation: Ask your oncology nurse about cold cap eligibility (not for hematologic malignancies, scalp metastases, or certain regimens). For warmth/style, choose soft chemo caps. Many hospitals and nonprofits (e.g., American Cancer Society, Headcovers Unlimited) provide free caps.
