I agree dermatologist.

Keep in mind that sebum works in supply and demand so when you over stimulate the scalp it will produce more sebum. so when you do the above treatments make sure you do them as gently as possible and try not to do them too much. Also try mixing some Tea tree oil in with them.

This has got to be frustrating, good luck to you.
Very Thick dry 3b BSL.
Fine, medium porosity
Right now I am using GVP conditioning balm for cowash and RO,
my hair loves protein.
for styling my base is BRHG I can use it alone but prefer with Curl Keeper. I sulphate poo once a month or so as needed.
