• Asian hair has twice the diameter and a much thicker cuticle than Caucasian hair. Most hair types have around five layers of cuticles while Asian hair has closer to ten.
• Asian’s have anywhere between 80,000 and 140,000 scalp hairs but, typically, they have fewer hairs per square centimetre than Caucasians. (They also tend to have less body and facial hair.) However, because the individual hair shafts are thicker, it gives the impression of greater hair density.
• Asian hair grows faster than Afro-Caribbean or Caucasian hair at a record rate of 1.3 cm a month, and it also has the longest cycle of growth, lasting up to nine years compared to the average two to seven years.
• Asian hair usually has higher porosity levels, absorbing and retaining moisture more quickly. The hair contains a medulla filled with plenty of dark pigment, which is thought to contribute to its shine and high moisture content. However, because Asian hair is thicker and sometimes longer, it also tends to lose more moisture, which can lead to dryness and split ends.
Commentary:
Given that Asian hair has ten layers, is porous and absorbs moisture, yet being thicker and longer, tends to lose more moisture, then it follows that hair should be washed preferably with a shampoo for dry hair. The conditioner should have lanolin as one of the ingredients. As well, there is no need to be averse to massaging your scalp as the natural oils in your scalp are still necessary to protect each hair as it grows out.
As for myself, I won't recommend a specific hair shampoo and conditioner because I use a dandruff shampoo for dry hair with zinc pyrithione int it, to help heal the scalp. About once every two days or so, I follow up with a medicated dandruff shampoo containing ketoconazole, an anti-fungal chemical, to manage the fungus responsible for dandruff.
