How to (Day 45)

So here's my tip for beachy weaves... twist a small section of hair &
flat iron over it twisted. Leave it to cool (it should stay twisted
on it's own) while doing the rest of your hair. once all are cool,
shake it out & voila, beachy waves. If you're hair is really hard to
twist, you may want to hairspray it before the flatiron, or if you
know the night before, put mousse in your hair.
