Summarize:

This can damage and further irritate the skin and can lead to an infection. You may even have some depilatory cream still under your nails. Wear loose clothes that won't rub or chafe the rash and possibly cause a friction burn. When using a cloth to wash the Nair off, don't rub too hard or scrub and try not to wipe the same area too many times. Depending on the type of soap and severity of the rash, you could make the rash worse by using soap when you shower. Pick a mild, fragrance-free cleaner or a gentle non-abrasive soap such as Cetaphil and use as little soap as possible. Do not use deodorant soaps. You might also try an oatmeal bath, which can give some relief. You can add ground oatmeal directly to warm bath water or make a sachet. You should wait 24 hours before applying deodorant, perfumes, makeup, or tanning lotions to the area where you've used the cream. These products can cause you to develop a rash or possibly a chemical burn. Wait 24 hours before going swimming or sunbathing. Choose unscented baby wipes that contain aloe in place of toilet paper if the rash is on your bikini area.
Don't touch or scratch the affected area. Use soap with care when you shower. Don't shave or reapply cream for 72 hours after using a depilatory cream. Use baby wipes instead of toilet paper.
