Hey, I’m not female, but I was caught by your post. I had/had shed hairs like that and it is followed up with itching and burning on my scalp. I tried everything.. Selsun blue used to help a bit, but... I have used borax for this and had better results. It clears those hairs for me.
Read into borax and try it. It’s like 4 dollars at target. I use 20 mule team borax. I’m telling you though, I use a lot ( two tablespoons in a bottle of hot water to dissolve it). But seriously try it. Borax is really good at ridding fungus and bacteria which is an issue for those with higher sebum production. Let me know how you do, but I think your condition can be helped with it like mine was.
Good luck. Read about it! A lot of people have awesome results with it
