im african american and my hair only grows 2-3 inches at the most. at times when i get my hair cut it can be as short as 1/2 an inch. i can imagine it may be a little difficult to maneuver the thick teeth of the lasercomb thru my hair. normally when i comb my hair i have to use a fine tooth comb to get all the way to my scalp. could that pose a problem if the laser light can't find a clear path to make contact with the scalp?
