ok im 21 and started using minoxidil. for my frontal thinning from about a month ago. right away it seemed to almost stop my fallout. Then, today during the 4th week, i noticed quite a bit of fallout. I got a feeling its the start of a big shed. I want to know if this has happened to you. If it has, how long did it go on for? and did it all come back? Im scared to keep takin it if the hair wont come back. Please respond. thanks
