To treat ingrown hairs after shaving, it is best to avoid irritants as much as possible. Use a fragrance-free lotion or cream at least 2 to 3 times a day and a fragrance-free soap like Dove. Avoid hot water during showers, baths, and saunas when the skin is irritated. After showering, gently pat the skin to leave a thin layer of moisture instead of rubbing it, then apply moisturizer. Protect the skin from the sun as needed if the area may be exposed. It is recommended to stop plucking hairs in that area to allow the skin to heal, as this can contribute to irritation and delay healing. Consider using a clean electric razor in that area for the least irritation.
