What if I never trimmed???

I just measured my growth for the first time last month. I measured it on the 10th of last month, and then again today (the 10th) and the difference is 3/4 of an inch.  I am now at just under 20 inches.  I'm pretty pleased about that actually   I always suspected that my hair grows pretty fast, but it's been an interesting experiment and one that I will keep doing (love statistics!).  

Anyway, I am trying to predict how long my hair will get by next Christmas.  That's a little over 12 months away, so based on last month's growth it will be just over 9 inches longer.  My hair would then be past my bra strap. That would be just fine with me and I'd consider that to be "long hair"   So.....my point/question is (and there IS one!), I would be at this length next year only if I did not trim it at all.  I'm assuming this would not be good, as everyone on here talks about trims and I figured that they are necessary.  I did plan on doing my own trims (sworn off hairdressers!), but then I was thinking today, what would happen if I just didn't trim at all?  I know my ends would look thin and wispy after a while, but besides the cosmetic appearance of them....would it do any harm?  I wear my hair up ALL the time now and I have not been able to see any split hairs at all (unless I am just not skilled/experienced enough to be able to spot them!) and maybe it's harder to see them in curly hair?  I have been taking EXCELLENT care of my hair, so it's ultra healthy right now.

How regularly do you all trim? What's the longest you've gone without a trim? What's the most growth you've gained in one year?  Do you think it's a BAD idea not to trim? Why?

Sorry so long and so many questions....

I think it depends on what your hair type is, and certainly your updos and careful treatment will help a lot.  I went for a year without a trim, but I also dyed my hair 2 or 3 times that year with permanent dye, and wore it down every day, not being very careful about how I brushed it.  The result of all of that for me was a trim almost up to my shoulders because it was terribly thin and split.  I'd just keep an eye on it, try not to trim it, then if you see it starts to look like it needs it, you can update your decision later.  A rare trim of 3mm. (1/8 inch) at a time so you're removing the very ends also can help a great deal without losing noticeable length.  

Missrini your hair is a great color red is real nice and it will look unbelievable at a longer length,  keep up the good work.  How long do you want it?

That would be the Hutterite faith. I'm not sure about other offshoots or classifications of Anabaptists though.

Missrini, microtrims help GREATLY even if you're not doing a full-fledged trim. I went through last year doing microtrims only, and search&destroy missions, but no big trims. This year I did a 1cm trim to "thicken up" the hemline. Without trims, my hair got really tangly at the ends. I agree with Susan that it really depends on your hair type. If you plan on wearing your hair mostly in updos, then not trimming won't be much of a problem. However since curly hair is soooo pretty when worn loose,  I think you should at least do microtrims so you can wear it down a lot.

Another thought to consider is that since your hair is wavy/curly, the difference in the growth rate of individual strands will be essentially unnoticeable, as opposed to those with straight hair, whose ends might start to look "fuzzy" and uneven after some months without a trim.  You could go the entire time without trimming the ends and it would look just fine.

If you do trim, the occasional micro-trim (1/8") suggested by Susan should be sufficient.  And definitely S&D for split-ends, whenever you have time & the inclination to do so.

Happy growing and as Anais says, we wanna see pics of your progress.
