Hi Deano59 ... It`s made in USA and not too many companies sell it in this part of the world.This one in UK does http://www.hair-development.com/shop/accessories/6/ Scroll down and you`ll see it . I haven`t bought from them yet as I slipped up and forgot about them and ordered my last lot from the USA which cost 40$ shipping.
This is another UK-based site with a lot of interesting products you might like to have a look at....again, I haven`t dealt with them so can`t give you any feedback .... they also have colour-correcting shampoos http://www.foreverhair.co.uk/Store/ShampCondition.htm
