Anyone here a hairstylist i need some advice?

I currently have blonde highlights and I'm constantly fighting with my hair cause it gets super super tangled 😩. I use my purple shampoo, the Its a 10 product, garnier oil, and another one its for split ends. Lol Apperantly it stopped working for me. And loosing my hair from hair loss PP it's not helping at all 😭.

Any products that will help my hair not get tangled and help my hair look and feel healthy. Plse
