Dragon Skin

Aside from pigment, dragons in my series are mammals so they are warm, but how much hair do they have? Obviously they have certain tufts of hair, visible in Athena’s drawings, across their bodies, how much hair do you think they have? Certainly they are not furry, and Starseth will never have hair like Jenny or Mattie that she can put in a clip, but as she matures, she is likely to have some hair, just not human like hair. What do you think?
