"A left hair part draws unconscious attention to the activities that are controlled by the left hemisphere of the brain, i.e. activities traditionally attributed to masculinity. A right hair part draws unconscious attention to the activities that are controlled by the right hemisphere of the brain, i.e. activities traditionally attributed to femininity.
A man who parts his hair on the right, and who is striving for positive assessment in a traditionally male role is at risk for having difficulties in interpersonal relationships, since he is sending a mixed, subconscious message by emphasizing the activities of the brain traditionally attributed to femininity.
A woman who parts her hair on the left, and who is striving for positive assessment in a traditionally male role (for example, in business or politics) will be taken more seriously than a woman with a right part, who is emphasizing mental processes that are traditionally attributed to femininity."
