Long hair vs Schwarzkopf Osis+ VOLUME UP and KEEP IT LIGHT

Hello.
I've tried a few products to hold long hair without residue and keep it manageable and so far I'm not satisfied with the results. Therefore, I have decided to record how the products that I have look like, and try the ones that you recommend, with the aim of finding the definitive product.
And what would this be? For me, it would be the one that gives volume to fine hair, that fixes, that offers a natural look, and that sets the hair back without the (so dreaded) typical line in the middle of jesus christ.
I hope we can help each other.

Are these the only products you use to get your hair like this? Would love to see a routine video or read how you take care of your hair. It would be enlightening!

I don't normally use products. For everyday use, I wear a ponytail (my hair is already very long). And about my routine... I wash it every two or three days. Nothing more. But it is true that until now I haven't uploaded a video of the shampoo I use, and I think it's important because it was the only one that solved my dandruff problem. But of course, what worked for me doesn't have to work for you. Beyond that... nothing special.
