So for the past week I've had itchiness on my scalp. My head is perfectly clean. I'm just now finding red... well pumps like on my scalp. They feel more like a bug bite because they don't have any discharge.

I did just recently change to a different shampoo and condition (a 2n1)

I did dye my hair 3 weeks prior

My head seems to itch less when the hair is up in a ponytail.

Is anyone aware of this happening to someone else? It's not a lice issue or anything. Is it common to be allergic to shampoo? I've never had sever allergy issues before.
