Itchy scalp


My head has been pretty itchy these couple days and I don’t know why. I usually take hot showers so maybe my scalp is just really dry but I’m not sure. I do suffer from dandruff but itsnever been itchy and also sometimes when I itch black little specks come out. I take a shower every day and I’m not quite sure if my scalp is really dry or irritated or what. Plz help
