I wear a bump cap at work, with earmuffs for the noise. I understand there's going to be an occasional itch for most people, but I'm constantly taking my gear off and scratching my head. I've got a thick head of curly hair, and it doesn't matter how short I keep it, there is constant itching. I clean the inner pads and straps of the bump cap with alcohol, as well as the earmuffs, at least twice per week. I've tried Head&Shoulders as well as Dove "anti-itch" shampoo with no luck. I accidentally left some styling gel in my hair before going to work once, and that was the only time I experienced relief. Naturally, I tried to do this again, but was left with the same itch. I don't get dandruff. Is there anything else I can do?
