Chemo hair loss usually begins one to three weeks after the first treatment, sometimes closer to four. That is the whole preparation window: the weeks between now and your first infusion. Hair loss is the side effect women most often tell us they fear, and it is one of the few you can prepare for concretely.
Hair Usually Starts Falling Out One to Three Weeks After the First Treatment
Most women notice shedding one to three weeks after their first chemotherapy treatment, sometimes closer to four. It usually shows up on the pillow first, then in the shower drain and the brush, sometimes in clumps while washing. Shedding continues through treatment and a few weeks past the last dose.
Many women feel it before they see it: the scalp turns tender or itchy. Eyebrows, eyelashes and body hair can thin too, usually weeks later and on their own schedule.
How much you lose depends on your drugs and your dose. Ask your oncologist what your regimen typically does. It is a normal question with a specific answer.
Key takeaway: Expect shedding one to three weeks in, often preceded by a tender scalp.
Cutting Your Hair Shorter First Makes the Shedding Easier to Manage
Short hair sheds less visibly, is less startling on the pillow, and sits better under a wig.
Some shave once the shedding starts; some let it happen. If you shave, use an electric razor — the scalp is tender and nicks heal slowly. Until then, skip bleach, color, perms, relaxers and heat tools.
Now is also the time to ask about scalp cooling, or cold caps. It reduces loss for some women on some drugs, though most who use it still lose hair, and not every center offers it. Headaches, hours of feeling cold and cost are real, so let your oncology team weigh it.
Biotin and similar supplements can interact with treatment and are not recommended during chemotherapy; what is safe to take is a care-team question.
Key takeaway: Cut it shorter first; take the scalp cooling question to your oncology team.
A Wig Matches Your Hair Best When You Choose It Before You Lose It
Choose a wig in the two or three weeks before your first treatment, while you still have your own hair to match against. Check the color in natural daylight, not store lighting. Your head measures slightly smaller once the hair is gone, so the cap has to be adjustable.
You will also have more energy for it now than in the months ahead.
Synthetic wigs are much easier to live with than human hair: they hold their style after washing instead of needing to be set each time.
A monofilament top has fibers hand-tied into fine mesh, so the part reads as scalp instead of a seam. It costs more than a standard cap top, and weighed against length and style, fit matters more.
Key takeaway: Match the color in daylight, and make sure the cap is adjustable.
Most Women End Up With More Than One Head Covering
Most build a rotation: a wig for appointments, a scarf or soft cap at home, a hat for errands. On warm days there are ways to stay cooler in a wig. A bare scalp burns quickly, so sunscreen or a hat outdoors.
Nights need their own plan: a bare scalp is tender, catches on cotton pillowcases, and gets cold. A soft sleep cap stays on better overnight than a scarf.
Not covering at all is a real option, not a lesser one. Hair loss is usually when a diagnosis becomes visible outside your household, and telling children plainly beats waiting for questions.
If cost is a barrier, ask a social worker at your treatment center about wig grants and donated-wig programs. They know which ones are open.
Key takeaway: Plan for a rotation rather than one perfect wig.
Nothing You Pick Now Is Permanent
Two or three weeks is enough time to do this well. A wig can be trimmed after you buy it, the scarves get rotated, and you can change your mind about covering your head at all. Hair usually grows back three to six months after the last treatment, often a different texture.
