With respect, I’d say there is no comparison between ‘normal’ wigs that you put on and remove each day, and the wigs known as ‘hair systems’ that are adhered to the scalp for long periods.
Hair systems ARE wigs, but they have more in common with toupees because they generally attach to the crown and blend into real hair at the edges.
I’m sure with a custom expert wig maker, something as realistic as a hair system could be produced in the style of a normal wig, I know they get commonly used in movies for instance. But no normal wig is going to cling to the scalp, and simulate real hair growth in everyday conditions with an active lifestyle in the same way as a system - especially for a man with shorter hair who doesn’t want a ton of density (which most normal wigs have). In fact I’m not aware of any regular wigs on the market or that are easily accessible that boast a realistic or low hair density; only hair system wigs really achieve this. And even if those kind of natural density wigs did exist, you’d still have to tape or glue the lace down to feel secure during the day and take it all off at night, so it’s even more maintenance.
It’s the difference between day and night!
Don’t get me wrong, if you found a product that worked for you then I’m very glad for you and maybe you discovered something I haven’t seen out there, but I can’t imagine most people wanting a believable natural look to work with their lifestyle would be able to find those results in a normal wig. From your name I’m assuming you‘re a woman so I understand it’s easier to pass off higher density and longer styles as realistic, but for shorter hair or with guys it‘s much more challenging to ‘get away’ with anything less than total authenticity!
