When a woman asks if she should cut her hair short, why do some women say, "I did it and I regret it. You will too."
Likewise someone might say, "It was the best thing I ever did. You should too."
What does her personal preference have to do with the first woman's preference? She isn't the same person and doesn't share the same opinions. Some people who cut off a lot of hair like it and some don't. Just because it happened to her doesn't mean it will to EVERYBODY else.
Most advice (on anything, really) is given based on one's personal experience. It's the same as if a friend asks whether she should buy a certain make of car. The people who owned one and had a bad experience will say she shouldn't, while the ones who owned one and had a good experience will say she should. Just because one person got a lemon doesn't mean everyone will.
I dont know,because I never do this. My sister in law does this and it drives me crazy. I'll say i got my hair cut,and she'll say,"how could you!" Her hair is below her waist,but so fried and dead and looks really thin. I tell her I'd rather have shorter more healthier hair then have dead weeds. Then I tell her if I want a mohawk,it's my priority,not hers.
Some people seem to think only they know what looks best on another
person, (and of course no two agree with each other on what that good
look is exactly). I think the people who say "you'll regret it" about
anything, without knowing you REALLY well, and knowing what YOU like
really well, are just those who lack the imagination to realize
that people like different things from what they like.
