20F : Limp Lifeless Fine Wavy Hair Haircare Tips

Hair Type: High Porosity, Fine Hair, Shoulder Length, 2b when styled with product 2a before wash day.

Current Products: Re'equil Dandruff Control Shampoo, L'Oreal Paris Fresh Hyaluron Conditioner, L'oreal Paris Dream Lengths Leave-In Conditioner, Fix My Curls Defining Hair Gel, L'Oréal Professionnel Absolut Repair Mask(1x a month)

I've been following blowout professor suggestions for washing fine hair and my scalp has been staying relatively clean for 1 more day with minimal build up but my hair has been laying flat and the curls seem weighed down even with scrunching the leave in, gel and all.

I'm at my limit please suggest me a better shampoo because I guess the re'equil one is too harsh for every wash. I used L'Oreal Paris Fresh Hyaluron Shampoo before which used to be fine but my hair scalp became extremely greasy by day 2 itself same with LBP lavender one. This one was working until I started using it for every wash instead of once a week, before my hair used to hold the style till day 2 properly. Should I just switch back to alternating between the re'equil one and either LBP or Hyaluron one?

Mainly looking for product recommendations and any method tips to work on
