clogged pores...I've got a bluezillion of them I'm trying to get rid of too. Supposedly glycolic acid helps those but for some reason it doesn't always help mine. They are a pain in the a** to get rid of!!
Are you dealing with the same Barber? Well I would use a antibiotic ointment such as A&D. but first wash the affected area with an anti-bacteria soap, and even alcohol. Make sure you tell the Barber to not just clean but Disinfect all of his tools 10 mins. before he cuts your sons hair. What does he use to give your son an edge up, does he use a razor or trimmers or both? If he use a razor your son might have sensitive skin and if that is the case have the barber only use trimmers! Some people can not tolerate a razor on their skin I am one of them I will break out a day or two after, so I just use trimmers. But if the bumps are on his head then it must be the clippers. Hope this helps any more questions feel free to ask.
