"For Normal Hair"

My shampoo has "For normal hair" written on it. This would normally be acceptable, but it sort of implies that there is such a thing as abnormal hair. I can imagine the scene now: Man walks into a chemists and says "Hi, I need some shampoo." and the woman behind the till gives him some, he looks at the packaging and goes "...Oh, no, this is for normal hair. I should have said really. My hair naturally assumes the shape of legendary English opening batsmen. Under my hat today I have Geoffrey Boycott playing a forward defensive. Yesterday it was Trescothick executing a magnificent square cut.", and the woman says "I'll see if we've got anything for that" and comes out holding a shampoo bottle that says "For hair that is NOT normal". I have a lot of time to think about these things in the bath. We also have something called Radox "Shower Therapy". I daren't use it lest I end up weeping on the floor shouting "Yes Dr Radox, I see it now, all my problems stem from my unrequited love in Primary 5! I need to let it go and be all the person I can be!". That's probably not what it does, but when it has such an ambiguous name I can never quite be certain, and why take that risk?
