I think an average looking woman can look pretty attractive if dressed well and with long silky hair, but in most cases a short cut won't boost their attractiveness.
Have you had a good look around - how many actually have "long silky hair"? I couldn't care less whether women have long or short hair, but I'm sick of all this rubbish about how the majority of women don't suit short hair (and yet those with long hair tied back somehow look okay? Several times I have thought someone had short hair only to find it was actually either tied back or up, so in actual fact they looked just like they would have with short hair), and also how hard it is to style. What styling does really short hair need - I just get up and go, I wash it once or twice a week, I don't own a brush or styling tools, it literally couldn't be easier. I also see people with long hair which drags down their face, and people with thin hair which really doesn't look great long - and yet there is this weird notion that ALL long hair looks lovely, and it suits everyone???
Long hair can look lovely, but so many only go to the hairdresser once a year - and we can tell. They tie it back when it needs washing - we can tell it needs washing, you aren't fooling anyone. Long hair, well maintained can look gorgeous, but if it's not then it can look awful. I also know several women who look stunning with short hair, and average with long.
Why do we need 18 pages of discussion about hair length? Some like long hair, some like short - end of . The amusing thing is, if celebrities and influencers suddenly all cut their hair short there would be a mad dash to the hairdressers!
