Will I shed if I change to Minoxidil 10% from Minoxidil 5%?

Good question. In my opinion if you had shed (they come back in 3 months or so) when you started the minoxidil at 5% then an increase shouldn't cause any more shedding. The only hairloss you will have will be a continued MPB hairloss if you stopped the therapy altogether.

In  my opinion, the chances of you having increased shedding are low as 5% can sustain the hairs in the growing phase. However, one of the benefits that you have obtained from minoxidil include increased size of the hair shafts. This produces an increased fullness of the scalp and may diminish with a  lower dose. In addition, improvements from minoxidil continue for approximately 12 months. If you lower the dose prior to this point, you will not get the maximum benefits as Minoxidil therapy is dose dependent. 

There is certainly a very good chance that a person will shed by lowering minoxidil from 10% to 5%. Absolutely I’ve seen it countless times.
