What's the Deal with Hair Steaming?

I have gone back and forth on this, and have finally decided it might be time to take the plunge!
Being a type 4 kinky, I constantly battle with dryness in my hair.  I pre-poo, and deep condition every week using a regular hooded dryer with my hair in a plastic cap.  I'm usually of the mind - If it ain't broke, don't fix it, but I keep hearing wonderful things about the benefits of steaming your hair.  Our friends at www.BlackHairInformation.com put together this sweet little infographic that outline some of the pluses of steaming.  Will you give it a whirl? -YB
