Greasy hair within 12-24 hours of washing

I am at a loss. I can wash my hair first thing in the morning and by the time I get home it’s greasy enough to do a no product slick back.

I usually double shampoo but come across a post a few weeks ago and a couple people had found that they preferred a single shampoo, so I tried that too, with no luck.

I have been trying different shampoo and conditioner combo’s for my entire life, my current routine is as follows:
Daily/every other day wash with Biolage Full Rescue (nearly out, will be trying Biolage hydrasource next)
Once a month I use the Ouai detox shampoo
Once a month I use the L’Oréal bond repair shampoo and conditioner
Once a week I use the Pantene volume shampoo and conditioner, in the 2 weeks of the month I’m not using the Pantene or Ouai

I’ve tried a handful of dry shampoo’s, the most recent being Amika Perk Up, the only difference they’ve made is that my hair feels awful until I wash it.

I spent 6 weeks blow drying my hair immediately after my shower, I couldn’t tell any difference, so I’ve gone back to mostly letting it air dry and blow drying when needed.

I usually wear my hair up but I have frequent headaches so I often need to have my hair down, but it looks horrendous.

What am I doing wrong? What can I do better?
