Ageing Hair in Asians and Caucasians

Chapter

Abstract

Hair differs across ethnicities and in changes with age. While limited, most literature agree that Asian ethnicities grey later than Caucasians, beginning at least 5 years later and perhaps regionally more. There are minimal differences in ethnicity with where greying begins, but there are differences comparing between gender. In males, greying begins at the temples and sideburns, while in women, it starts along the hairline. In addition, males’ hair diameter decreases linearly with age, leading to an onset of noticeable changes by the mid to late 20s. On the other hand, in women, the diameter reduction is associated with menopause, and hence hair thinning is not usually felt until the mid to late 40s. Asian hair fibres are more regular in shape and are of larger diameter. This provides for a stronger, more damage-resistant hair. Appropriate care of Asian hair differs mostly due to the differences in basic structure and susceptibility to damage. Asian subjects also prefer smooth, straight hair. This is supported by hair care products with higher active deposition and is achieved by using separate rinse-off conditioning. Older individuals should avoid damage by being gentle with wet hair, avoiding excessive mechanical damage and refraining from chemical damage as in colouring, straightening or perming. Minimal data has been collected in Asians, so while today Asian and Caucasian hair look similar in terms of age, undiscovered differences may still remain.
