some people start growing thinker hair mid cycle, others just don't thin more, and others get a faster cycle and the shed is just hairs going into telogen so they can start anagen sooner. Minoxidil will no make your hair loss worse. If you get a shed, you know your hair cycle is going faster. If you don't get a shed, then you can be in one of the first two categories, but it will be more difficult to tell right away. Non shedders have to wait 4-6 months to see if they are getting good results. Shedders know right away that their hair cycle is speeding up. It does not mean you know you are getting above average results, it just means you know you are at least responding.
