I'm a owner of the advanced 7 model and had a question. When I'm using my laser comb.

Is the entire surface area in between the teeth getting the laser light? or is it specifically where the laser dots are pointed on the scalp that is getting the laser?

The entire area inside the teeth is red from the light, but I can still see the 7 dots concentrated on certain spots, so are those the only spots getting the light?

(my head is buzzed if it matters)
