Any shampoo that makes hair taste better?

by Guillotine(Yah)

I know this may sound like a weird question but I'm really curious because some hair tastes better than others and I want to know which shampoos people with amazing tasting hair use so I can make my girlfriend use it in her hair so her hair can taste the best it can. Also bonus if you can tell me what foods are the best in hair to add even better taste to the hair. I know hair tasting/hair in mouth is a weird fetish to have but I just want to satisfy it the best I can.
