Joking answer: At SS1, Nappa loses his mustache and grows one yellow hair. At SS2, Nappa loses his eyebrows too and grows more hair. At SS3, Nappa loses all his hairs, while his head shines instead. Every 30 seconds, the shine will change from Red to Yellow, Yellow to Green, and Green to Red like a traffic light. LOL —
