Itching isn’t always an issue after back hair removal, but if your skin tends to get aggravated after shaving, good after care can make all the difference. Just after you shave or trim your back fuzz, rinse off your back and your body grooming tool with cool water. Pat the skin dry with a soft towel, and then apply moisturiser. Do this every time you shower. Switch your usual body wash with an exfoliating scrub, or a brush, to tease out any hairs that might want to grow inwards.
