I have been using Kirklands 5% minoxidil for 2 months and normally buzz cut my hair to grade zero. I have just let it grow out for three weeks so that it looks like a microphone and have noticed that the complete top of my head has thinned all over compared with two months ago, i.e. pretty much transparent. Is this normal? I never notice any shedding due to the shortness of my hair. Of course I am going to continue to use this for atleast another 4 months to give it a fair chance.
