OP, it's hard to tell whether your ends are thin or not. When you do a fat twist,
assuming your hair is all the same length, then you have the hair at the axis of the twist not losing length because it basically hangs straight, while the hair on the outside of the twist has to travel inward first before the twisting starts.
you are right,
my hair isn't, maybe it's just not a thinning ends but just the longest of the 2 strand which were twisted. !
You can tell if your need to trim depending on how long it's been since your last dusting or trimming.
my last trim was in APRIL and since i've decided to moisturize and seal every single day. and to not exposed my ends.
People who wait to SEE splits slay me.
Im sorry don't slap me, or.. maybe u can v_v !
There's no common sense IMO in believing that your hair is invincible and will not wear away especially if you're not PS 24/7. If you're combing, styling...if your hair is coming into contact with anything, then it's been exposed to friction that is wearing it away. The ends being most vulnerable are being worn down whether you can see it or not. The only way to prevent extensive damage is snip the ends regularly so you can remove the starting of splits before they travel up the strand to a point where breakage is obvious.
So rather than wait to see whether you have splits, just get a regular dusting schedule and enjoy the peace of mind of knowing your ends are in good shape. Because whether you like it or not, splits are inevitable.
If you had done thin twists, we could better tell you if your ends are thinning. This is what my twists look like:
I have the coiling at the ends, but there isn't a thinning. I think you'd have to make small twists to be able to tell for sure. What you're looking at in your pics might be the same effect one sees in a ponytail. Hair could fall to the same length but when you put it in a ponytail, the center hair hangs lower than the sides of the pony because it didn't have to travel inward first before hanging down.
