Recently on occasions I have had this strange feeling on my scalp. Feels like someone has pulled my hair very tightly and the scalp is tingling. When I touch it it can feel tender, as if bruised. Its outside not inside my head (at least I don't think I'm imagining it ha ha) Any ideas any one.
I had something similar a couple of years ago. Turned out I'd 'burned' my scalp by using a strong anti-dandruff shampoo called Nizoral. Have you used something similar? Since then I've been using only T-Gel, which I highly recommend, and have had no further problems.
