Some of the main human characters in Super Robot Friend Forever! have very specific hairstyles, some a bit more mundane, others a lot more out there. This post is to summarize each of them and how they are generally supposed to look.

Yoshimi's hair is supposed to have three pointy spikes all across, sort of porcupine-like. When I first drew her, her hair was essentially an afterthought, with a ton of spikes that were never consistent until the designs were tweaked perfectly to the way they are now.

Seth's is sort of like an afro, but has 6 central, albeit uneven, bumps at the front. I kinda took inspiration from my own weird hair (which is a real afro) for it. Akira, Yoshimi's mother, has a similar hairstyle, but with 8 more evened out bumps instead of 6.

Heather has semi-long hair with very noticable signs of messiness, fitting to her wacky personality. Heather's design was (sort of) based on many girls I knew in school, who had similar messy unkempt hair (one of them even had green dye lol).
all of these characters should look recognizable as silhouettes, since that's what makes a good character design of course
