What Causes Rashes On A Bald Head Along With Sudden Headache?

Questions so that I can advise:
Detailed Answer:
Hello and welcome,
Would you be able/willing to upload a few good digital pictures so that I can see what the rash looks like? Best is if there is good lighting but no flash. At least 2 pictures, one up close so I can see what the skin looks like and one farther away so I can see the overall pattern.
This may be a contact dermatitis. The headache may be a tension headache if the muscles were tense from the irritation of the rash, but I can't say for sure. Was the headache worse at the base of the head/neck or in specific areas?
If you can list the ingredients in the aftershave, I can take a look at that.
Also, is your hat made of wool or something else? And is it new and a deep color dye?


As for the headache, the focal point was definitely near the rash. However, for about a day it went around the entire circumference of my head. It's not an issue anymore but when it was no longer my entire head, I still felt the headache around the rash.
My hat is a polyester acrylic blend and yes it is new.
Thoughts on this
Detailed Answer:
Hi -
I'm giving this some thought but can't say I know with absolute certainty what's going on. Here are some of my thoughts:
The hat has XXXXXXX that was irritating on the skin, particularly if the aftershave has alcohol or something irritating in it. Maybe washing the hat, if it's washable, might get some of whatever might be irritating in it out. It might have some sort of treatment in it too, such as a chemical to make it water resistant.
Another thought is that the hat is tight and this caused irritation in certain areas.
If the pain from the headache felt like a typical headache, it might be that the muscles tightened, maybe from the inflammation from the rash.
If the pain was superficial, in the skin, it might be that you were feeling the inflammation from the rash.
I don't know that humidity would cause a bad reaction with the aftershave as, after all, those are the conditions that people usually put aftershave on their face. However, having moisture on your skin and then having cloth on top of it might have caused irritation.
