If you have just been to a salon and had your dreads 'done' they may of put some type of moose or spray in your hair that your scalp doesn't agree with. Baba Fats has really said it all at what to do, whatever shampoo or soap your using, just change to another, but with out using a shampoo conditioner blend. If you did scaif your scalp with the latch hook then of course the healing process will make your scalp so itchy. Ask yourself questions like was your scalp itchy before you had your dreads done and if not just go back to whatever you were using before you dreaded as long as theres no conditioner in the product.
Hope this helps.
