How can one tell if Nappa has become a Super Saiyan?


We can identify Super Saiyans by the change in the colour of their hair.  
With Nappa being bald, how could we identify he has become a Super Saiyan? Is
it only by the increase in power?




It's not only by hair.

As you can see, the eyebrows and eye color changes as well. So you'll be able
to tell.
