Hiya! 

Got my dreads 3 months ago now and still haven't got a proper dread shampoo. I live in NZ and there isn't any available here. Importing would be too expensive. I have used some tea tree oil based shampoo that are clear and don't seem to leave my head oily or anything. I am worried it will slow down/stop the locking though... Also my scalp is not a happy scalp in general so the tea tree is good for me so far. 

Anybody from NZ here? What shampoo do you use? 

Thanks
