I've had some Outback Organics tea tree shampoo and conditioner since before Christmas and have only recently got round to using them. When I first opened the bottle, the smell was lovely, sometimes tea tree can have an overpowering smell but this wasn't the case.
The shampoo is creamy and lathers well, my hair smells fresher and is noticeably softer and shinier since using these. I am also happy with how long a bottle will last. I am only having to use a third of the amount of shampoo compared to other brands, so very cost effective.
Outback Organics get a 10/10 from me for their shampoo and conditioner. The best I have used in a long time.
