Not practical to thin hair from a poly system as it is in the case of lace.....
it looks like a uniform density ...the front isn`t graduated enough.....
I think, you need to order a system with a more age-appropriate density and more accurate colour-match....there appears to be a difference..your side hair looks like it`s bordering on white and the system looks more a silver colour [bearing in mind it can / may be my monitor] .... it may be time to try a different supplier ?? Why not try a TL system ? There`s an excellent exchange-rate between the Dollar and Sterling ....currently 1£ =1.69$ !! You could be pleasantly surprised at the difference .
