Wigs, coloured hair sprays and hair dye are the three Halloween costume items that could leave hair damaged or the scalp irritated, according to Dr Balwi, a hair surgeon at Elithair. The warning does not suggest that everyone who uses them will lose hair, but that tight fittings, harsh products or poor removal techniques can increase the risk of problems.
Wigs and the Risk of Traction Alopecia
Wigs offer a way to change hairstyle without a permanent commitment, but how they are worn matters. The British Association of Dermatologists explains that traction alopecia can develop when hair is subjected to repeated pulling, with tight hairstyles and extensions among the known causes.
Dr Balwi said: "Securing wigs with clips, bands, or glue can intensify tension along the hairline, putting additional stress on the hair follicles, blocking scalp pores, and increasing the risk of traction alopecia". Choosing a comfortable fit and avoiding excessive tension can help reduce the risk, while regular breaks from wearing a wig may also help.
Coloured Sprays and Hair Dye
Temporary coloured sprays appeal to anyone wanting a bold look without committing to a permanent dye. Dr Balwi warned that using large amounts can make removal harder, adding: "In some cases, attempts to remove the colour may result in damage to the hair due to overwashing."
Hair dye presents a different concern, as ingredients can trigger skin reactions in some people. NHS guidance lists itching, burning, dryness, soreness and blisters among possible symptoms, and says reactions can take up to 72 hours to develop.
Advice and Precautions
The NHS advises testing hair dye before use, following the instructions on the packaging and washing the scalp thoroughly with mild shampoo if a reaction occurs. Anyone whose symptoms worsen should seek advice from a GP or pharmacist, while sudden swelling of the mouth or throat or breathing difficulties require emergency help.
Dr Balwi said redness, itching, irritation, bumps or unusual hair loss should prompt people to reassess their hair products or costume choices. For Halloween, the simplest precautions are to avoid tight wigs, use temporary sprays sparingly and treat any scalp discomfort as a reason to stop rather than push through.
