This is why. First of all, I'm always wondering why, even though I'm not damaging my hair in any way, it doesn't look like the girl's on the shampoo commercial. It always seems to end up that I look on here and find out I've been doing something wrong to make my hair worse. Then I'm always looking in the mirror, wondering what my hair'd look like if I didn't do all the wrong things. I also find out a bunch of other things you need to do for healthy hair, and all the upkeep it requires to have it at its maximum potential. I'm always looking to see if certain areas seem thinner than other, I keep a lookout on any strands that fall out. Now I'm wondering: am I stressing out too much over this? Is it really so much to ask for really nice hair? Apparently. I don't know, maybe I'm just imagining things. Does anyone else ever feel like this? Sometimes it makes me wish I never wanted long hair.

If you make a physical list of things to do (ex: condition, don't shampoo everyday, avoid extensive styling, etc.) it may help you out.
Perhaps you could elaborate on what your specific problems are right now so that we could help you create such a list?

It's not really about my problems, it's that I feel that my hair's never the way I want it to be, and that I'm always doing something wrong. Another thing: doesn't stress make your hair fall out? What if all this worrying about my hair is having adverse effects? I wonder if upkeeping with hair is even worth it. I wish I never wanted to dye my hair in the first place.

Practice makes perfect. I've been dying my hair the last 4 years (since 6th grade, basically) and only the last 6-8 months have I been doing a well enough job to think my hair looks good. Might be 'cause I'm older, might be 'cause I might horrendous mistakes and learned from them. ;)
I don't think stress causes your hair to fall out...? Never heard of it happening anyways.

First of all, I don't think anyone's hair is like those shampoo girls' hair.
I think you're a little too obsessed with your hair. Stressing doesn't cause it to fall out as far as I know, but it does cause it to get gray.
Is your hair thin, thick, or in the middle? Is it curly, wavy, or straight? How long is it? What's your usual routine and how often do you shampoo and condition? What kind of prossessing has your hair been through(bleaching, dying, other chemical prossessing)?
All of those can affect how you have to take care of your hair.

My hair is a harsh mistress.
I've been dying it for almost 10 years now though so I doubt I'll be stopping anytime soon haha.
The hair you see on TV is a bunch of bullshit in my opinion, just like all the 'perfect people' that you see in the media.
I'm convinced it's all wigs and computer-altered anyways.
My hair may not be in the best condition, it may not be styled very fancy, and it may not be perfect.
Right now I spend 40 hours of my week wearing a white hair net and a hard hat anyways.
But it's just hair, there's more to life than hair.
Relax, don't worry about it so much.
It's okay to have questions and concerns though.
Just ask!

If you're annoyed with your hair why not go and have a hair cut at a good salon? A good cut can really make all the difference. I'd also spend some time learning how to style it. My hair used to sit like a big lump since bleaching until I learned how to blow dry it properly. It's not perfect but it looks better.

If you've got split-ends find an understanding hair dresser whos happy to cut off only that, so then the split won't spread. You'd have to get way nore stressed than this to get alopecia(the hair falling out thing linked to stress). Conditioner is a savior use it after every wash, and don't worry about using loads even if it says concentrate. Ask people you know with nice hair what they use, don't always listen to the people at the hairdressers [sold me £7.50 worth of shite, completely screwed up my scalp, didn't slow down dye fade and dried up my hair]. That's all i can think of for now

Some people just have awkward hair. I'm one of those people. I spent years cursing it but at some point you just have to suck it up and make the best of what you have. I have very thick, stubborn, wavy, frizzy hair. Typical Irish hair, if you will. But I found what products work for me and despite all the bleaching, dying and straightening it looks soft, straight and smooth. There are always people on here who can recommend products and techniques. And yeah, a good cut makes all the difference.

I'm not sure whether this is true or not, I think my mom asked her doctor or something why my hair might be falling out. She said that, because I have long hair, it might be too weighted. But then why doesn't girl's hair fall out? She claims it's a genetic thing guys have, just like how girls get big hips. But there are plenty of guys with long hair...
Just wanted to throw that out, does anyone believe that, or know if there's any relevance (probably mispelled that) to it?
