It didn't work for me, but using a roller to curl up the end of the twists. If all else fails, use some brown gel and put a scrunchie on the ends to make a twist bun.
Hi, newbie here, long time lurker.
I'm relaxed and what works great for me is the 3 strand twist.
The twist stays closed without the use of a rubber band.
when i did flat twists on my mom during her transition i used blue perm rods (the smallest ones) and they stayed very nicely. when i did two-strand twists i used straws and bobby pins.
