So this is how a super saiyan is made.

- Goku fights Frieza
- Gets stressed due to getting his ass kicked, plus millions of lifes depend on his win
- The power up shout is actually a stress/frustration shout
- After 3 episodes of stress (shouting) uses all pigments
- Now he has a light colored hair
