/cgl/ - Cosplay & EGL

Ah A hair thread, perfect.
I have sorta short wavy hair (more wavy near the ends), sorta dry really bad frizz going on. If I grow it out the wavy usually starts around my chin, right now anyway I been using Aussie Smooth for Shampoo and Moist for conditioner (when I bought my big bottles with the pump the store was out of Moist Shampoo so I bought the smooth) and its been like 6 months with the same big bottles.
I started to notice my head starts to Itch really badly if I use the same brand shampoo and conditioner for too long, even if I change types through out the time I was using it. (before someone asks no I don't have lice, I'm checked regularly)
This has happened with multiple brands over the last few years. Does anyone else experiences this? No one else in my family has this problem.
Can anyone recommend what I can use next?
I have used Tresemme, Pantine, VO5, White Rain, Nexxus, Ossart, Mane and Tail, and Head & Shoulders (this really makes my head itch)
