he should not have to use concealer on his brand new hair system... whats the point in buying a hair system if you need to use concealer on it ?

Dont wanna pay 300$ (got long hair) and be un-happy with the product.
I hope this get resolved correctly

And why using un-clear value like % why not simply using let say 30 HPC (30 per per square centimeter) from what I read 50 hair per centimeter is good.

can we know the value behind dencity % ? its seem not precise enough.
