I wear the "Puff Bun" quite frequently these days and will be rocking it next week when I remove the twists under my wig and free my strands. I have a headband that I like for this style, but it is too tight. My head is crying for mercy when I remove the band. So, I turned to LHCF to ask how to stretch a headband for a puff. I received a lot of answers and ultimately decided to go the "band-over-chair" route.
First, I sprayed it to "loosen things up"
Then I left it to sit on the back of a dining room chair back
Ta-da! However, I am letting it sit until I wear it next week. Still not loose enough.
