Skin is not outdated technology. They actually can work very well. Its just another option, especially for such a small area if you are just getting a small system for your crown area.

U have 3 options basically. continue to use concealers and try diff non messy brands .. I recommend prothik. You could get 1 or 2 partial hair systems .. one for your crown and either a small partial for your front hairline to bring it down completely Or two temple area partials. Or you could just shave it all off on top and get a regular type of hair system.

I mean are you happy with the look after concealers? cause wearing a hair system isn't maintenance free, Instead of cleaning concealer of your head u would be cleaning glue, or tape, u know, it has its own type of maintenance.

Your forehead looks a little high, I think you could bring it down more than 2cm. Maybe you should think about getting two partials or just get one unit and cut it the piece off of it you need from a template or something.

It really is hard to give advice cause its such a personal kind of decision.
