I remember seeing a movie i believe was from the 80: a kid couldnt grow hair and somehow came across this cream/paste stuff that made his hair grow extra fast. I feel like peanut butter was the main ingredient The hair wouldn’t stop growing, and i remember he was in class with anotjer kid behind him cutting his gair as it grew and he got in trouble by the twacher. there was more than that happening but thats all I remember. any help would be qppreciated
