It is impossible to understand the importance of human scalp hair without appreciating its sexual role - there is a vital link between sexuality and hair. We use it to draw attention to ourselves, to attract and entice, to flaunt and seduce. Hair is one of the single most important parts of our anatomy affecting our psyche.

Our hair can make our day or ruin it, make us elated or feel incredibly miserable. Some of us will take more care of it, spend more time on it and nurture it more than any other part of our body. Our anxiety about it is often beyond belief. We can love it and caress it, loathe it and curse it, but the joy of good-looking, well-behaved hair framing oour face gives a psychological boost like no other.
