I only noticed it yesterday - it's triangular in shape and is approx 1.51.51cm in size.
The skin is slightly dry and I can see a few empty follicles and a few short sharpish hairs, almost as though they have been cut (but she denies it), but I would imagine regrowth from a hair that has fallen out naturally would be quite fine.
I don't know if this could be related, but I have noticed over that past few weeks that she is pulling out individual hairs as a habit. I have obviously asked her to stop, but to no avail (she's a chronic nail-biter too). She says when she pulls hairs out she's doing it from the sideburn area, and this tallies with what I have seen her doing.
I will make an appointment with her GP tomorrow, but am sitting here pondering and wondered if anyone on here has any experience.
Thanks.
