Hi Sanctuary, This happened first go for me too and i have not had this problem since. Usually the hair is in a resting phase then falls out naturally. I think this may be due to the essential fatty acids from the butter penetrating the hair in order for new thicker hair to grow. But if the problem persists it may be other factors you may need to look into. You can also use it as a hair mask instead of shampoo.
But with many hair loss shampoo's your hair must fall out in order for new hair to grow. I also use natural herbal shampoos rather then conventional shampoos as conventional shampoos are known to make hair fall like the ones in the supermarket. I have a horsetail and rosemary shampoo i use to somettimes mix with the shea or coco.
Here is some information of other places that i have found that use emu oil and shea butter. http://www.longhairlovers.com/emu_oil_hair_treatment.html

You are right about the emu oil bit, but shea butter does the same as it has essential fatty acids. You can also add variations of other oils like jojoba, coconut oil(very good) or avocado oil etc.
For awhile i have been using the shea butter without emu oil and it has still done wonders. I want to show you pictures of my baby hair that has regrown but its not showing up good on camera.
I order mine online aswell. I have a local health food store i ask to order some in for me but it takes 2 weeks to wait for it. So i might aswell order it myself. Somettimes i also checkout auction sites like oztion.com.au and ebay.com.au for some. this place is the one your talking about W. A http://www.aussiesoapsupplies.com.au/Butters-Waxes-c-5.html
