Product recommendation for oriental hair please

I currently use Aussie hair products because I love the smell! I'm a massage therapist but have a trade card for Alan Howard. I would like to try some shampoo/conditioner but I can't believe how much choice there is and have no idea what to look for, shelves and shelves of brands!!! I am Chinese and have long hair which is thick and straight. It gets greasy at the roots very quickly but a little dry at the ends. If anyone can recommend a brand and type of product for me it would be much appreciated. Thank you.
