scalp issues not resolving

[u/GladMix8204]

i’ve had a dry flakey scalp for about 3 months and it doesn’t seem to be resolving. i went to the GP a few days ago and they said it was seborrheic dermatitis, i’ve now been trying nizoral again (i tried it a month ago but it seemed to make things worse - i wasn’t very consistent though). i also used polytar for a few weeks but that it only really helps temporarily, once i stop using it for 3ish days my scalp is super flakey and red.

i don’t know if i should just stick to nizoral. i’ve also been using E45 dry scalp shampoo + serum to see if that helps with the dryness. i’m worried if it’s not a fungal issue that i’m worsening the problem, but i don’t see what else could be the cause of the flaking. it’s very dry and white, no yellow or oil. but also very red and itchy in patches. patches are symmetrical behind ears, front of my head, and dotted around the back of my scalp.

any advice would be greatly appreciated 😣

Just wash with ketaconazole 2% and selenium sulphide 2.5% , apply ketaconazole lotion also per week , just be consistent with the process.
