More detail

On the body, ingrown hairs are most common in the bikini line, underarms, legs and the back of the neck. Tightly curled hair cut by a razor or snapped by waxing has a sharp tip that curls back into the skin or grows sideways under it. The body treats the hair as a splinter, producing a red, dark or skin-coloured bump that may contain pus. Repeated inflammation leaves dark marks that often last longer than the bumps. Prevention works better than treatment: soften hair with warm water first, use a sharp single blade or an electric trimmer that leaves a little stubble, shave in the direction of growth and avoid stretching the skin. Gentle chemical exfoliants (such as salicylic or glycolic acid lotions) used a few times a week help free trapped hairs. Laser hair removal by an experienced practitioner using a device suitable for dark skin can be a long-term option.

What to avoid and why

Avoid plucking.

Common mistakes

• Shaving against the grain.

Body care basics in a hot climate

Heat and humidity mean the body sweats more, which feeds the bacteria and yeasts that cause odour, rashes and some types of body acne. A daily lukewarm shower with a gentle, soap-free or mild cleanser, thorough drying of skin folds and between toes, and fresh, breathable cotton clothing prevent many problems. Moisturise straight after bathing while skin is still damp so water is sealed in; this matters even in humid months because frequent washing strips natural oils, and it matters most during harmattan. Avoid sharing towels, razors and sponges, which spread fungal and bacterial infections. When shaving, use a sharp blade, shave with the grain and do not stretch the skin; for curly hair a guarded trimmer is often better. Be cautious with body-lightening, 'carrot' or 'toning' lotions: many contain undeclared steroids or mercury. If a rash spreads, keeps coming back, or appears with fever, see a doctor rather than trying more creams.

Choosing body products

For most people an unscented, gentle cleanser and a plain moisturiser are enough. Antiperspirants containing aluminium salts are the most effective way to reduce sweating and are best applied at night to dry skin. Fragranced body sprays and deodorants are a common cause of allergy; fragrance-free options are kinder to sensitive skin. Aerosol products are easy to over-apply and some have been recalled for benzene contamination, so roll-ons and creams are a sensible default. For fungal rashes, plain antifungal creams such as clotrimazole are better than combination creams containing strong steroids, which can make infections spread. Always check for a NAFDAC number and a full ingredient list.

Questions to ask your doctor or pharmacist

Useful questions include: What do you think is causing this? Is it likely to come back, and how can I prevent it? Which products should I stop? How long before I should expect improvement, and when should I come back if it isn't better? Are there side effects to watch for? Is this treatment safe if I am pregnant, breastfeeding or for my child? Writing your questions down, bringing your products (or photos of their labels) and taking dated photos of the problem make an appointment much more useful.
