As JRob said above--- `he`ll get away with 75% on top if it comes in[back] spot-on`.. however, if the ventilator get`s a bit `carried away`... it will seem quite thick/heavy.... Toplace densities are a degree heavier than the equivalent on many other system-suppliers.... 75% on Toplace is equal to 100 % on `others` therefore if the ventilator goes a bit heavier, you can end up with a really heavy-looking head of hair, which you`ll most likely have to thin out a bit. I`d go with 70% on the top, 75% on the back [crown to nape ] and 65% on the sides.... it won`t really be too obvious to the eye as such when you take it out of the envelope on delivery-day, but it will help to give a nice finished -look, once styled-in. Order a graduated front too [they normally are graduated anyway] Younger guys can get away with higher densities but to be honest, there`s no point going too high just for the sake of it----- a medium density gives some scalp show-through in places and looks way more natural and `real`... that`s where the lace comes into it`s `own`as it`s practically invisible to the casual eye among the hair... I like to have that little bit extra density at the back as it allows the stylist to layer it in and thin[ moderately if required] here and there with a thinning scissors. Just mark your densities on the Template as appropriate and some arrows for the hair direction ,especially at the back and enclose your pic. They generally seem to get it pretty much accurate anyway....best regards, paul.
p.s.--cover over any marks you make on the template with a layer of sellotape to prevent them possibly getting smudged or even wiped off when being handled. Also, you might like to request no name-tag to be attached to the system at the back [they ALWAYS stitch them on] ..I`ve found they put them very near the perimeter and they feel a little `bulky`and can be a bit `` in the way`` if you are using tapes there at the nape.. I forgot to request none on my recent order...I know some guys cut them off with a blade but I`m wary of slicing the lace there by accident--- it`s not a `major`drama but you might prefer a `clean`perimeter -line.
