If chemotherapy is ahead of you, the question of hair loss can feel enormous — and the question of a wig for chemo can feel overwhelming to sort out before treatment even begins. The good news is that there is a gentle, practical path through it, and starting early gives you more control, more choices, and more calm. This guide walks you through what to know about medical wigs before treatment starts, so you can prepare with confidence instead of scrambling later.
Why Timing Matters: Get Fitted Before Hair Loss Begins
Many women tell us the single biggest regret is waiting until hair loss had already started. When you're fitted before treatment begins, you can:
- Match your current hair color, texture, and part while you still have it
- Try on several styles without fatigue or scalp tenderness
- Have your piece ready and comfortable the moment you need it
- Practice wearing it in private, at your own pace
Hair loss from chemo typically begins 2 to 4 weeks after the first infusion, sometimes faster with certain drug combinations. That window is your planning time — use it.
How Medical Wigs and Insurance Prescriptions Work
A wig purchased for hair loss related to a medical condition is often called a cranial prosthesis. This term matters because it is the language insurers and medical suppliers use.
At a high level:
- Ask your oncology team for a written prescription or "medical necessity letter" stating the diagnosis.
- Request the relevant billing code from your supplier or insurance office (commonly A9282 for a cranial prosthesis).
- Ask your insurer in advance whether they reimburse, how much, and what documentation they require.
Not every plan covers wigs, and coverage varies widely — but it is always worth asking. Your care team's social worker or patient navigator can often help you advocate.
Choosing a Scalp-Friendly Cap
During treatment your scalp can become tender, dry, and sensitive. The cap underneath your wig matters as much as the hair itself.
Look for these features
- A soft, breathable base made from bamboo or a gentle knit
- A seamless or flat-seam interior that won't press into skin
- A velvet or no-itch edge band that stays put without gripping
- An adjustable fit, so it can relax as the head changes
What to Expect with Hair Loss Timing
Loss can be gradual or sudden. Some women shed in handfuls; others wake with most of it gone. Both are normal.

Whatever the pattern, your wig is a tool — a soft one — not a mask. Wear it when it helps, and put it down when it doesn't.
An Emotional and Practical Checklist
Preparation is part practical, part emotional. Here is a starting list:
- Schedule your fitting 3 to 4 weeks before treatment, if possible
- Bring a photo of yourself with a hairstyle you love
- Buy a satin pillowcase to protect both scalp and wig at night
- Pack a small wig kit: soft brush, cap liner, and a gentle shampoo
- Talk to your care team about a referral letter for insurance
Most of all, remember that this season is temporary and you are allowed to feel every part of it. When you're ready to explore your options, the HALO medical wig collection is designed with soft caps and gentle materials made for this exact journey — at your pace, on your terms.
