How do you treat an area on the top of the head which is red, pus looking but no real drainage. Just a red area on the to of his head in the balding area of his scalp. This occurred after wearing an acrylic beanie in the rain for approximately 4-6 hours 2 days ago.
Hello, there are 2 possible reasons for that one is Cyrillic caps are made up of synthetic materials. Also, perspiration difficult through the cap. Apart from that, the cap make the scalp warm and sweat more also. Wearing it for longer time make scalp sweaty. So it can produce the worn area a sweat rash, just like you described.  Other thing is it can be, contact dermatitis to the synthetic material it is made up of.  What can you do is you can change your cap to a wool one which is a natural material, and it let perspiration well also. Therefore, it causes scalp less sweaty and warm. Also, if you are having contact dermatitis to Cyrillic it would also be reduced from wool.  Topical anti-steroidal +antibacterial cream would help in healing the rash. Keep the area well Chat Doctor.  Lactocalamine lotion can reduce itching.  Don't use the cap when the climate is warm. It will aggravate the problem.
