All right. We're joined by jennifer goldstein, beauty director for "prevention" magazine, and three women who have been getting a blowout all morning. Lara's with us. Asking the important questions. Let's start with our first model, charla. We have a look at her before photo. There she is. And now, take a look at her blowout. You look great. Jennifer, I want to ask you. How much is too much? Women are really getting into it. My friends used to consider it a treat. Now, they'll forgo other luxuries to get their blowouts. It is heat. You want to limit blowouts to about three a week. Maybe not try to blow dry on the weekends so your hair can air dry and get a break from the damaging heat. You love it? We have our next model here. This is christina. We have her before picture when she came into the studios. Here she is. And here is christina now. Beautiful. I want to ask. This is a little bit of a straighter look. You have a naturally curly look. Do you like it? It looks sleek. If there's a good blowout, is there a drier that is better? You want the professional drier that has the wattage that will give you the heat you need. Look for something at the minimum, 1,875 watts. It's counterintuitive. You want it hotter. It will be less damaging. And you will get the sleek finish. I love the curly to wavy like that. We have amanda before she came into our studios. Beautiful hair. Let's turn her around. She looks beautiful. This is a very nice, loose, sexy look. You can get this -- the key right here is a brush. If you have a round brush, you will get the wave shape. You want nylon or boar bristles. Metal bristles will be damaging. We appreciate all of the great tips to do it at home and save even more money. Ladies, thank you. You all look lovely. We appreciate it.
