The only solution is to be proud of it - and it is nothing to be ashamed of (my baldness is in fact a solar panel for a sex machine).
Being bald is fine and if you're not self-conscious about it, it's odd how no-one really notices. It's a question of confidence. I noticed myself starting to go bald in my late teens, which was a bit traumatic, but when I actually took a look around, there were quite a few blokes losing their hair, very few of whom gave it a moment's notice.
The only time you're really in for ridicule is if you get all self-conscious and try to do something silly to hide it.
Regaine is a mug's game - look at Andrew Neil also known by Private Eye as "Brillo" for the headful of pubes Regaine has given him.
Equally stupid is the Arthur Scargill weetabix look.
And of course, there is the Bobby Charlton comb-over.
Or there is the expensive Travolta wig and the cheap Wogan wig.
But the worst of the worst are hair implants - look at this and weep that anyone is so stupid. You get a patch which covers the area which has receded then, guess what, the hair recedes a bit more and you are left with a clump of seaweed on the beach after the tide has gone out (a la Russ Abbot) and you have to keep getting more and more implants as the hairline ebbs away.
