use a hose to prevent burns.
What makes steam different from spraying your hair with some water or other concoction and scrunching it again, is that you do not need to add additional styling products, there is no drying time, and your hair will feel and look soft - not crunchy. If it's still dry or cold or windy, your hair will eventually lose some of the moisture it takes on during steaming - (lose some volume and curl), but not completely and it takes several hours to wear off.
Today was one of those very windy and dry days. I use the diffuser to support my hair while it's exposed to steam - this helps it re-curl or re-wave better. I only steam each spot for about 10 seconds, and I return to each spot about twice.
This is my hair before steaming. My hair is wavy. It can be more or less wavy/curly depending on the weather and how I cut and style it. You'll pardon the indoor-lighting difficulty I have with light-colored walls and light-colored hair, I hope.©Science-y Hair Blog 2013
In less than 5 minutes of "work" it had perked up quite a bit, though you can't see the cute curls in the back.
Just sharing a happy hair tip! Because I don't live in the tropics, I've been doing this a lot over the past couple months and it always gives me good results. Nowhere near as frizzy as you might expect. Not very portable, though. Sigh. Can't have it all.
