What is this?

You can try gently massaging some coconut oil or baby oil onto the scalp, leave it for about 15-20 mins, then use a soft brush or fine-tooth comb to gently loosen the flakes before washing off with baby shampoo. Don’t pick at it though! It usually clears up on its own over time. If it gets really stubborn or starts spreading, your PD can recommend a medicated shampoo.
