greasy hair all of a sudden

Please help me!!! A couple of weeks ago, I washed my hair as normal (using Pantene Smooth) and blow dried it, and my fringe was almost immediately greasy at the little front strands. I’ve had a fringe for over a year + used this shampoo and NEVER experienced something like this. I have not changed my moisturiser, I don’t use hair products such as mousse/gel, I would only use heat protectant on the ends of my hair when blow drying (tried drying without, still greasy) I don’t put conditioner on my roots ever. I bought the redken tea tree clarifying shampoo, didn’t help (shampooed twice), went to my hairdresser to get my fringe cut as I needed it anyway, they gave me a scalp shampoo and that also hasn’t helped. I’ve used dry shampoo in the past as I do have naturally oily skin/scalp so I’ve had to use it in-between washes. Ive only used a natural powder one and Klorane one for dark hair. Now, it seems the dry shampoo isn’t even lasting the whole day. So I’m not sure if it’s becoming resistant to it or what? I bought another standard supermarket shampoo and tried that, still greasy after a few hours. I can’t live with washing my hair and it being immediately greasy. I’ve never had to wash my hair every day in the past despite having slightly oily skin/scalp. I could at least go 2 days. I have quite fine hair but a lot of it. Posting from australia so Australian friendly products would be great. Please help!!!! Any advice appreciated, I cannot live like this lol😭😭
