Narmak thanks for your advice. I've gone with the exact recommendation you suggested. I'm literally getting the derma roller and fin today, already have minoxidil. I've got to at least try do something. I regret leaving it too late. The lighting in the pics doesn't help to be honest. Apart from the crown area, I've still got all the hair at the front and top, just lightened in colour and thinned really bad. I know it's gonna take at least a year and not expecting miracles but excited to see if this combination strengthens and darkens the hair already there. If I don't get any result at least I can say I tried and be happier knowing I did something about it. Then it'll be pretty much shave it off and get smp. More to life than hair, like your health and kids health or a roof over your head. I'll keep updating.
Thanks
