Hank Green is an American YouTuber, science communicator, novelist, stand-up comedian, and entrepreneur. He produces the YouTube channel Vlogbrothers with his older brother, author John Green, and hosts the educational YouTube channels Crash Course and SciShow. He has advocated for and organized social activism, created and hosted a number of other YouTube channels and podcasts, released music albums, and amassed a large following on TikTok.

Considering Hank's recent cancer-induced change in hair texture, I've captioned the training data such that the two hair types can be evoked via "...Hank Green with straight hair..." or "...Hank Green with curly hair...". In my experience not specifying the hair types will result in straight hair.
