Ok so today I noticed a bald patch on my leg just above me knee, its like someone has shaved the hair off and the hairs are now like stubble where they are growing back.. Does anyone know what this could be? (Yes I done the worse thing and googled, luckily there was nothing bad, it actually said nothing). I wear skinny jeans so could this of pulled the hairs off? Or could this be an illness? such as alopecia? This is the only patch I have noticed.
