And why does it have a sticky. We've established it works only slightly better than random chance. The science behind it is nonexistent and the guy isn't even around. As Sec said in another thread, all one really has to do is damage the cortex of one's hair. There are probably many ways to do this, all of the more effective ones (like hair bleaching) require the follicle to be opened with a base. The "Mac Method" closes the follicle right off with an two acids, and then uses a Tide as a (diluted) base. We have zero evidence that it's effective enough to be recommended as much as it is, and while I am all for rituals to calm the mind, I don't think this accomplishes even that very well. Unfortunately, I have no better suggestion.
