So I've never really had a dry scalp other than one spot at the nape of my neck. Recently I've noticed flakes in my scalp and my head isn't even itchy (other than the normal occasional itch). I haven't changed any routine other than adding everlasting sunshine as my conditioner styler.

I recieved a sample of Eden peppermint tea tree shampoo and tried that yesterday but I still have flakes.

Help!!! The weather is cold here and we have been running our heater. Could this be a symptom of winter?
