Let's start at the beginning of your day...
1 - Use the right shampoo and conditioner. Yes! It really does make a big difference. If you're prone to big hair, you'll want to use a very emollient shampoo that will add some weight to your hair. I like Aveda's Smooth Infusion line.
2 - Don't rinse out your conditioner all the way. Leave in just a little bit to help tame the mane.
4 - Add a leave-in conditioner to prep your hair and protect it from the heat of styling. Adding a straightening serum
5 - Having a good blow drier is huge! Make sure it's Tourmaline Charged, Ionic and at least 1800 watts. Tourmaline is a mineral that when heated will seal moisture to your cuticle, and the positive ions make for a faster, frizz-free blowout. My favorite blow drier is the Sedu Revolution
7 - Finish with a few drops of glossing serum from the ponytail down and a light mist of aerosol hairspray. If you have fly-aways, spray some hairspray on your hands and smooth down what's sticking out. After this finish, your blow dry should last a few days.
9 - Try going a few days before washing your hair. If you get oily easily, use a dry shampoo: spray at the root, give it a minute to soak up the oil, then blow dry out the excess and brush your hair with a paddle brush. Your hair and scalp will thank you. Your natural oils are really the best conditioner for your hair, and a good dry shampoo can re-vamp a 2-day old blow out like nobody's business.
10 - If you MUST wash your hair, apply conditioner from the pony tail down and just shampoo your scalp. Hair doesn't need to be washed every day, and shampooing your ends too frequently will remove your hair's natural oils, which are nature's best frizz fighters.
