I never expect human hair ends to stay put when the hair is brand new, so I just keep redoing them when chilling watching TV till they are "trained". After a few washes, they unravel less and eventually stop. But for some reason, these ends seem to be holding better than I remember ever witnessing.
In 2007, when I used Wet N Wavy (Beverly Johnson) from the BSS, the hair behaved as I expected. It was only wavy at the very ends where I stopped braiding when they were freshly done:
Later when I washed my hair, the hair unraveled up to where my hair ended and only then did the entire area beyond my own hair get wavy (after being wet and unraveling).
With this hair, the wavy part you see is the part beyond my hair but I am surprised to see it wavy even though it is braided and even before I wet it. I don't know if this is common with hisandher (last time I had their hair was 2005 so I cannot remember) but I like!
I guess the waves are helping the hair stay braided to the ends better?
