“The inroads of the Western barber were far more rapid than those of the Western tailor. Liberated Meiji women went in for a pompadour known as ‘eaves’, from its way of projecting outwards in a sheltering sweep. A few geisha and courtesans adopted Western dress from mid-Meiji, and several wore what became known as the ‘shampoo coiffure’, from its resemblance to hair let down for washing and not put back up again.”
