Some chemotherapy drugs act on rapidly dividing cells, which means they can also affect the hair follicles that produce hair, leading to hair loss (alopecia). Shedding often begins around two to three weeks after treatment starts, and the extent varies with the type and dose of medication. An important point is that in most cases hair grows back after treatment ends. The first regrowth may differ slightly in color, thickness, or curl, but it usually settles over time.
While hair is falling out, the scalp can become more sensitive, feeling tingly or itchy. Using a gentle, mild shampoo and washing softly with lukewarm water can help. It is wise to temporarily avoid very hot hair dryers, vigorous brushing, and chemically harsh treatments such as perms or dyeing. Trimming hair short in advance can also ease the emotional strain of sudden shedding.
Hats and headscarves are not only about appearance; they are practical tools that protect the scalp. Without hair, the scalp is directly exposed to sunlight (ultraviolet, UV) and cold, so a hat with a brim or one that fully covers the head is helpful when going out. Soft, breathable materials such as cotton or bamboo fiber reduce itching and sweat irritation, and items with flat inner seams feel more comfortable. Keeping several options — a thin scarf for summer, a warm beanie for winter — makes daily life easier. If you consider a wig, adjusting ventilation and wearing time helps keep the scalp from becoming sore.
If the scalp becomes red and raw, oozes, hurts significantly, or develops inflammation where a hat or wig sits, do not wait — let your care team know. Hair loss can affect not only appearance but also emotional well-being, so talking openly with family or your medical team is an important part of care.
