In need of help with my hair..

I have straight hair, oily scalp.. it gets super “flat” on top and that really bothers me. I am also very prone to dandruff.

I also plan on getting some mild color work (that will cost quite a bit for me), the problem then it’s how can I protect that.. if I use silicones I will need to remove the buildup.. but if I do that I mess up my color, on top of everything I can get dandruff and flat hair very easily.

So.. Protecting color, avoiding silicone buildup, avoiding dandruff all at the same time?

Western products are not doing it for me, well.. the ones that I could try are a bit too pricey for me anyway.

Is there any shampoo/conditioner recommendation (that wouldn’t break the bank?).

Should I give up silicones entirely? I’m so lost D:
