Asian hair has a reputation for being very coarse, but in fact there are many different textures of Asian hair. One example is slightly wavy Asian hair. This type of hair is usually very fine and has an irregular shape which produces the "wave."
With the typical straight Asian hair there are multiple variations which depend on so many genetic conditions, for example: "thick, straight, hard and coarse" compared to "soft, fine and straight." These variations start with the hair cuticle: how many hairs come from the cuticle and what shape the cuticle is. For example, African American hair cuticles are more "flat" compared to Asian and Caucasian, which produces the unique texture of African American hair.
Today though, you can change your hair texture. Hair bleaching techniques and hair products have advanced so much over the years that procedures are easier and more successful. The price point for these products and procedures is now more affordable and the training of hair colorists is far superior.
Finally, Asians tend to have an oily scalp necessitating the hair to be washed everyday to avoid the appearance of it not looking fresh and clean.
