ok heres my say on hollywood an celebs,without chance of getting myself in trouble.hair pieces are used alot more than u know,its not a handful its alottt.all movies do something to male leads hair of a certain age or if they are thin younger,a small thin spot looks like a a huge bald hole on camera.hd is reality on crack.people say its just real life,no,u cant see a drop of prespiration actually form in real life,u can in hd.hd ruined many older artists career,where as you could pile on layers of makeup and hair in the old days,now days it has to be unperceptible to the eye have no texture but be perfect.do you know how hard that is to do.do u know how hard it is for anyone to withstand,actors arent models so many have very reallll issues.men are having to like never before step up their game,its more so the exception to not have somethingggg done to hair.good hair goes unseen,thats the point you dont know.its the few bad you know about or those who transitioned less than graceful in the public eye.if you see a man in his late 30's eary 40's with a gorgeous head of flowing hair say what percentage of the population has that.what go into any makeup trailer on any set open a cabinet labeled male prostethics youll find more male hair pieces than female pieces.the leads are kept by actor(worn) or key stylist there are always 2 of every style.one to be cleaned one that is worn.we typically rebond daily due heat of lighting unless we are trying to preserve continuity and we dont wanna risk postion changing in scene,we film the same scene over several days manyyy times.it is always rebonded for costume changes.the slew of pieces in man makeup trailer are for extras,those are applied in front of anyone,they are extras with leads they arent applied in front of anyone except in actors personal trailer on set,no pics exist no cellphones are allowed to be on during process.ive had mine taken away as i entered.its done in the back of trailer in a completely blocked out part so no press or paparazz can posssibly see,you can not have the piece in your hand it must be in a container before you leave makeup trailer to go to actors trailer to apply,incase press were to photgraph you with piece in hand entering.you can be sued for breach of contract and held liable for actors damages to image if you reveal it,no one want to be sued for 100 million dollars because he blabbed about a toupee.i didnt say anything to get me in trouble because i know what i can an cant say.industry standard adhesive is kd 151 matte lace adhesive its very strong but so drying to piece.
