Re: How to use the 187
there actually isn't two layers. the white hairs are white all the way down, same with the black ones. the black ones are just shorter than the white ones, giving the look of a hair that is black at the base and white at the top.
the short black ones are there to space out the the white ones. this cause less hair to pick up product and less product deposited on the face. this makes foundation and highly pigmented products to go on shearer.
you can use it to apply cream/liquid foundation (giving an airbrushed looked), cream/powder blush (highly pigmented goes on lighter), MSF (it was launched with these initially), and pretty much any and every product you can imagine.
