Ingrown hairs are found under a thin layer of dead skin cells that cover the hair follicle, and precisely these dont allow the hair to break through the surface.
RESOLUTION AND PREVENTION
Exfoliate once a week
Wait for the hair to be atleast the right length before you remove it
Thread rather than tweezing as tweezing (if done wrongly) can break the hair rather than pulling it from the root
LETS ALL AVOID THOSE HORRIBLE INGROWNS BY DOING THE RIGHT THING!!!!!! XX Tandi
