I could agree with giving male Kerrans a lion's mane type of adornment, like some Vah Shir had. Besides that specific example? No. Beast races do not need hair. Kerrans and ratonga are already covered in fur, Iksar and Sarnak are reptillian, and frogloks are amphibious. inb4 "durr, but magic and fantasy!" copout No. Magic is not an excuse to have something so absolutely ridiculous as a froglok (or Iksar, or Kerran, or Ratonga, or Sarnak) with hair.
