Asian Hair, Caucasians Hair

Asian hair contains a medulla filled with plenty of dark pigment, thought to contribute to their shine and high moisture content. Asian hair also tends to grow longer than African and Caucasian hair as it has the longest growth cycle of the three hair types: up to nine years. addition it grows faster than African and Caucasian hair - about 1.3 cm (0.5in) per month, compared to the 1.2cm (0.4in) and 0.9 cm of the two other hair types respectively.

On average, Asians also shed fewer hairs a day than Africans or Caucasians, and Asian men tend to experience less balding (Caucasians have the highest incidence of male- pattern baldness).

Greying of hair also starts later. However, there is evidence that Asian women over 45 tend to experience more overall thinning of hair than their Caucasian and African counterparts, and because Asian hair is thicker and often longer than other hair types it tends to lose more moisture, which leads to dryness and split ends.

About 70 per cent of Caucasians have finely textured hair, and 30 per cent have medium-textured or coarse hair. Colour and texture appear to be linked: blondes tend to have the finest hair, while redheads tend to have the coarsest. Although Asian hair is thicker, Caucasian hair has the highest density of the three hair types.
