Hi I am a male in my 20's, I have noticed my hair thinning out around the sides of my hairline, the Center piece of my hairline is still as thick as usual so is my crown and sides, the hair looks to be thinning in a Y formation around the thick center piece, I noticed this when I shaved my hair 2 weeks back, at the moment I have weird mole looking things on my scalp and my scalp is also sensitive, my brother and father still have full heads of hair, my scalp is also quite itchy
