Thanks for choosing HCM.
First of all, please understand that you can not stop hair loss by worrying over it; on the contrary you will worsen it, as has been the case.
If you have familial male pattern baldness
, no medicine is going to stop hair loss.
There are a couple of local medications which reduce the rate of hair loss for some time which will start again once you stop these.
Please accept the fact that this is some thing which can't be arrested by medicines forever.
Stop combing harshly & with force; Stop experimenting with various OTC drugs & shampoos etc.
If you have head lice
, Crusts etc in scalp
they can be treated by your doctor.
The other causes like deficiency disorders can be tackled by your doctor.
In lighter vein-' God made a few perfect heads, rest He covered with hairs!'
Think over & stop losing sleep.
There are some surgical procedures to implant hairs etc which you can try.
