I heard of this a loong time ago before lace fronts became so popular. It was this white man stylist and he called the lf a hair replacement system. He charged so much that you had to call for a consultation to get the price. Anyhoo he suggest that you shave your head so the system fits better. After visiting that site I realized my hair situation wasn't that bad.
That is crazyness....it is too much!!!!
I wouldn't do it because LF look horrible to me. *IMO* Weaves and regular wigs look much better. However, I would keep short hair if I wore weaves or wigs 90% of the time. Trying to stuff long hair under a weave or wig is more trouble than its worth.
I stay wearing wigs, it's my go-to protective style! But I am not shaving nan hair off of this head for a wig. GTFOOHWTBS.
