Most Saiya-Jin have black spiky hair that defies gravity and black eyes. There’s also the occasion that a Saiya-Jin has dark brown hair. They have tanned skin from being outside and fighting so much.
The hair of a Saiya-jin remains the same for their entire life and whenever it is cut off, it will grow back to its original length.But never longer than that.
Facial hair is something optional for a Saiya-Jin. They can make their bodies stop it from making if they so desire.
There are several exceptions to the standard appearance of the Saiya-Jin due to the selective breeding that takes place in their ranks.
. The Saiya-Jins grow very, very old. They can become a few hundred years old, easily. However, most of them are killed before they live to see that day. xD This is why the Saiya-Jin age very slowly. The appearance of a Saiya-Jin remains that of a teenager for something around the first hundred years of his life. (Not counting the first 25, in which they develop into their teenage form.)
