I normally just cut one every time I see one lol. Once a month, I'll part my hair a middle part, seek and destroy those split little ends. If I feel I have too many, which I often do because I have fine curly hair that I iron it often lol, I'll take my hair cutting scissors wash my hair and brush it all back and snip off like an 8th of an inch straight across.
I don't trust salons and I've never been to one so my mom took care of my hair until last year when I decided to wear it natural. Anyway I cut off some "rough ends" a couple weeks ago and ended up with uneven/choppy hair.
