The anus and surrounding skin should be kept clean and dry. To do this:

After bowel movements, gently wipe the area around the anus with a soft cloth or toilet paper, without rubbing.
Do not use any cleansing lotions.
A bath can be taken after bowel movements. Afterwards, the area can be dried with a soft towel or a hairdryer.
Unscented talcum powder can be applied to the skin around the anus (this helps to keep the area dry).
Foods that increase itching should be avoided.
Tight clothing and clothing that puts pressure on the anal area should be avoided.
Cotton underwear should be worn.
