The World of Hair: A Scientific Companion by John Gray
If properly looked after hair can be shaped, moulded, coloured and made to shine with "health". If neglected it can look shoddy, become dull and lifeless, and lead to many even more damaging attempts to restore it to its former glory. This book explores the nature of hair, its care and maintenance, the cosmetic and medical problems which can affect it and ultimately the way in which the individual, the stylist and the hair care industry can work together to create "healthy hair".
