Recommendations for dry shampoos!

Hi all! I’m very new to this sub but a lot of the issues I read about, I can relate to and I was hoping to get some recommendations for dry shampoos! I’ve tried a couple of those and honestly they just seem to make my scalp greasier and oilier.

For full transparency, I would apply it from a distance of 15-20 cms only on the roots of my hair. Would gently distribute the product with my fingers over the scalp so as to get the product evenly on my scalp. However, I’ve tried two different products (one was a local brand that I don’t really remember the name of, but the second was L’Oréal Elvital dream length), and both got my scalp feeling icky, greasy and scratchy under an hour!

I’d given up on dry shampoos till I read a few comments on completely different posts and subs about dry shampoo being good for texture in the past week. I was already somewhat sure something was wrong in terms of my technique or the product but now I’m a 100% certain of it! Could you kindly recommend some techniques/videos/products that could help? My hair is straight, fine strands but high density and tends to fall flat on my head! I don’t have a recent photo of it, but if I find something online that’s similar to my hair type, I will link it as a comment below!!

Thank you! ♥️
