I have left a few millimeters of growing hair just in front of the ear area --the edge of the system [the red line I drew on the pic ] sits just behind that..it`s just for visual -effect but my hair is very straight and `fine`..... as younggun`s hair is long-ish and quite wavy/curly it probably won`t be necessary to `keep`any...mine being so straight [was my reasoning] that if the system hair slightly `lifted`away from the skin it would be noticeable so keeping just the very front bit of my own would `mask`that if it happened ---and it does! It`s something you might like to consider too younggun....Paul.
