I have about shoulder length hair that is ragged on the ends, but not damaged. I wear my hair in a braided bun on the crown of my head and cover it with a cap. I do not believe it is a sin to cut(trim) my hair. I need to know which end cut I should use, either a blunt, straight-across trim or a curved end cut? Should I part my hair in the middle, comb it to the sides and then cut the ends in back or what should I do first? Comb all of my hair straight back and down and then cut the ends in a blunt or cruved trim?

Thank you.

Sorry, I meant to say my hair is below my shoulder blades. Since I will always be braiding my hair up into a bun on the crown of my head, will cutting it straight across keep the ends of the braid from being wildly out of similar length as they are now?

I have very long hair that I wear in a bun every day, lots of buns actually.  I always cut my hair straight across and I have never had a problem tucking ends or what have you. 

I also trim my own hair very easily, quickly, and accurately.  I wouldn't listen to people who say "only have a trained professional" do it, because that it just hogs wash! (no offense, hairstylists)  For something simple like a trim, you can absolutely do it yourself.

To trim hair straight across, comb your hair and put it in a low, tight ponytail, right at the base of your neck, with NO part (comb the hair straight back).  Use scrunchie to do this, NOT a no-slip hair-tie.  Stand with your back straight and your head straight forward, reach around (or have someone help you if need be, I do it myself though) and begin pulling the scrunchie STRAIGHT down (do not follow the curve of your back, you want to go straight down toward the floor).  Pull the scrunchie all the way down and stop just above the point you want to trim off.  then, simply cut the hair below the scrunchie.  Use VERY sharp hair scissors (I actually use my insanely sharp Ginghers, which are fabric scissors, but they work well for my thick hair), et VOILA!  Perfectly straight trim, every time!  If your hair is short enough that you can not see your ends when they are in a pony tail, you might want to have someone else to the cutting, but it's so simple that even someone who has never touched hair before could do it.


Good Luck!
