Review (1/5): Love the product; hate the seller
GK hair products work really well for me, with dry, colored, curly hair relaxed by keratin. But their pump tops are often defective, which is a huge problem when you buy the large bottles. Customer service is the pits. They want to make you jump through hoops, sending them pictures (of what ? The pump is stuck down or shooting air!) when all I wanted was a new freaking pump top. Bottom line, good for your hair but seriously aggravating. I've had at least four pump top failures in two tears.
