Tyra BanksTHE LOOK Straight with deep side part HOW-TO Star with a smoothing balm on wet hair, advises Wendy Bond of the Oscar Bond Salon in N.Y.C. Blow-dry with a large round brush to get lift at the roots. Finish by running a flat iron over the hair and a pea-size amount of pomade, "from the middle to the ends of the hair," says Bond. INSIDER TRICK Avoid applying smoothing products too close to the root, as it can look too flat and greasy. BUY ONLINE NOW Strait Line Smoother Straightening Balm, L'Anza, $13.50; beauty-mart.com.
