It will eventually fade out - depending on how big the dot is. Just keep washing your hair as normal, and stay away from people that wish to draw on you using a Sharpie marker.
If u wait too long to get sharpie out by washing hair will it come out? Someone put a dot of sharpie in my hair and I used a cloth but it felt useless
It will wash out. Why would you let someone write on you with a sharpie?
That will never come out. Go shopping and grab a handful and color all your hair.
~ kidding ~
It should fade out in a couple of washings.
