calamine may help but shaving "against the grain" may have resulted in a condition called folliculitis -- a skin infection that involves the hair follicles. an antibacterial cream may be preferable.
can i use calamine lotion on a sympton like heat rash? . i have had a shaved head for over 20 years and decided to shave my head against the grain. use bump patrol afterwards as i normally do. no problem until the next day i developed what looks like heat rash as i work outside daily but i also wear a hat. never had ingrown hair problems.
