I haven’t changed how I clean my hair or how many times a week I clean my hair but it’s been getting soooo oily lately

I’ve tried using less conditioner and keeping my head under the water a little longer then normal thinking that maybe I’m just not washing everything out but it’s not helping

I washed my hair yesterday and today it was greasy which is ridiculous because it’s never oily that fast so I put dry shampoo in my hair and it’s the end of the day now and my hair is so oily that I can move it a certain way and it stays there 🤢

It’s never done this before and idk what to do
