IN GROWN HAIR...Ouch! Leave it alone, let it break and heal on it's own or you WILL GET A SCAR! This is due to handling the penis and a hair becoming trapped under the skin. You can keep an eye on it and when you see the hair surface take a tweezer and gently pull it out. DO NOT SQUEEZE IT! Allow the fluid to drain naturally. Using a hot compress on the pimple can help bring the hair to the surface from which you can tweeze it.
