My hair is frizzy, rough textured in parts, and confusing.

What can I do to make my hair look even remotely nice?

I swear when I was younger it used to be way sleeker so no idea what has happened.

The picture is of my air dried no product hair.

I know someone is going to say try the curly girl method but honest Ive tried it and it does absolutely nothing. The back of my hair has 0 curl and the front just has one small slightly wavy section.

I don’t know if its not conditioned enough or lacking in something else??

Current routine:

Aussie volume shampoo Pantene speak and shine conditioner Tresemme Keratin Smooth Heat Protect Spray Sometimes - elvive miracle hair perfector oil

Never really use heat on my hair

Im a very greasy gal so I need to wash my hair every 2 days really.
