So, I wonder if you have dry scalp/skin? I get this. I get my hair colored. When I do sometimes, it can really REALLY itch and it's almost always in the dead of winter when we have our furnace on. I don't see anything on my scalp. It's not flaking or anything but man oh man, it itches. And it goes down my neck and on my ears. Can you try a different shampoo? Can you make your water a little cooler (hot water dries skin)? Try NOT to scratch your scalp. Because I was having this happened when I got my hair colored, I read a lot. Scratching hair follicles a lot can cause injury to them. Literally that damage can result in hair loss. Ugh. So, I fight the urge. I put different oils directly onto my scalp and I found a product called Scalpicin. It's over the counter and is like hydrocotisone in liquid form for your scalp. However, checking with your doctor wouldn't be a bad idea. I also used dandruf and scalp shampoos even though I didn't have flaking. If this persists, get checked by a dermatologist. Let me know what happens. I know that itching of the head can drive you nuts!!
