I have a 7 year old who has been getting bumps in the back of his head lately. I took him to the barber and the owner looked at his head and stated that he should no longer get a bald fade cut because that could be the cause. He recommended that I get a product called Skin Tight, which helps with the razor bumps. Currently my son has scabs on the back where the bumps were. My question is: Is that a good sign or bad one? Can anyone recommend something that does work.
