How to get beach waves

So how do you get those awesome beach waves without using a ton of heat and salt spray products, which have a tendency to dry out your hair?

I found a great solution, although not perfect because it takes several hours to dry. One way to do it is to dry your hair about 75% and then proceed with this method.

Section your hair in about 4-6 pieces, twist it, roll it into a mini bun and bobby pin it. Do this all around your hair and sleep on it. I like to add some product, like a leave in conditioner or argan oil so that it keeps it’s ropey texture once you let the buns out. And the best part about it is there is no heat.
