Just got out of the shower, please help 🙃

So this is my first time having long hair. I don’t really know how to take care of it so I’ve just been going off information I’ve been given from all over the place. I wash my hair whenever it starts feeling oily, which is about every other day(an extra day or two if I use soft water). I use cool to lukewarm water and shampoo twice. I don’t really use conditioner often because it makes my hair oily by the next day, but if I do it’s every couple of months just on the ends. Today I used conditioner just because I was thinking the flakiness was from dryness, but it’s the same as it always is. Maybe it just cause I have dark hair so it’s more visible, but I don’t think that’s the problem. I’ll appreciate any advice y’all have to offer ❤️
