1. "very short" is a very relative term. for one, I consider hair "just below ears" still "kind of long"
2. I noticed one thing that I tend to present as an universal axiom, and at least in my opinion it is: Any and all women look better with long hair, and any and all women look the best with their long hair loose (no fancy hairstyles, ponytails, anytails, anything).
3. I "made" this "axiom" about 8 years ago. Since then, I've met only ONE girl which might possibly look worse (/less good) with long hair, and she's kind of male type (in a strange female way) face-wise.
4. When my (girl)friends (as in actual girlfriends, and also female friends) shorten their hair, I usually scream painfuly inside, then, having no other option, I get used to it and patiently wait for it to grow again.
5. there's a point where variations in hair length don't matter anymore, for me it's "longer than 4 cm below shoulders". Any changes beyond this limit are recognizable, but do not affect the overall look of "womanly long hair" that's so important and beneficial imo.
