DD 12 has dandruff. Can get quite bad - a few years ago she had flakes the size of my fingertip coming out. Used tea tree and it worked a treat on her scalp, unfortunately it turned out she’s allergic to it. The back of her neck was red, sore and flakey for weeks. So obviously stopped using that
it calmed down for a while, but seems to be coming back recently. Use Head and Shoulders on it, but it doesn’t seem to be having any affect
Is there any good solutions for teenage dandruff that isn’t tea tree or head and shoulders?
