ok...I get it. Well so here's the plan of attack.
If you are trying to trim more relaxed ends off, the easiest way to do this is to wet the hair and then trim, that way you can clearly see where the natural hair is and the relaxed hair is. Cause when i chopped the first time, I still had relaxed ends that i didn't couldn't see when my natural 4b hair dried. Cut off as much as you feel comfortable with. The way I did this was to section my hair in 4 sections and put each in a bun and clip it. Then take down one section, and part it into smaller section and clip as much as you want. if your hair starts to dry, just mist the section with a spray bottle. After you finish the section, pin it back and do the others.
Once you are completly natural there are different ways to trim. There is the twist and trim technique: basically put hair in 2 strand twists with damp hair, and when they dry, trim the ends of each twist. Now because some hair strands curl up more, the hair may not be exactly even, but if you aren't blowdrying, that probably isn't necessary.
You can also have the hair blow or pressed lightly and then trim, and then wet it to get back to your natural texture. But be sure the pressing is light, because some peices might straighten permanently. Also you can just do the section thing with natural hair.
On my natural hair I do the sections, but sometimes if I see a crazy hair when it's twisted I might snip at it, but usually i don't. Since I have been taking care of my ends, i only seem to trim every 4-6 months. Hope this helps.
