My ends? No. I just believe in regular trimming. I keep my hair in protective styles 100% of the time.
But (unpopular opinion), I'm not of the belief that just because it's in protective styles, the ends won't need maintenance. (not knocking those that do)
Actually, when I grew my hair to WL, I was on a 12 wk/3 month trimming/dusting schedule. Re-growing my hair now, I pushed it to 4 months to see more growth quicker, but now I'm wondering if I should just stick to my old 3 month rule.
My ends aren't damaged. My stylist (who does my protective styles) and her colleagues always comment on how super healthy my hair looks and thick and asking who does my trims (I'm too afraid to say it's just me LOL).
I just like to 'stay ahead' of the splits and trim objectively and thoroughly. That's hard to do when your emotions are involved and you're eager to get back the hair you once had. So, I sometimes trim/dust twice in a row because I feel I can only stomach to take off but so much each time
-- which may not be what I feel is enough to ensure my hair stays healthy.
Basically, I'm paranoid of trimming inadequately and suffering setbacks later because of it. I never want to be back here again.
So, i'd rather take the slower and cautious route. 'Better to be safe than sorry' ideology. My bottom layers should be APL by now, for instance. I just cut them back from collarbone length that I did in December to shoulder length--- letting the top layers catch up some (they are chin length currently).
