Hair's the Scoop

Extend the life of your next salon style with these expert tips and tricks, courtesy of celebrity stylist Sebastian Scolarici of Serge Normant at John Frieda Salon in NYC:

Lighten Up
Whether you're having your hair done or styling at home, avoid using too many products, as the buildup will cause your tresses to fall flat at a faster rate.

Go Boar
A boar-bristle brush may be an investment, but it's one worth making. The densely packed, natural fibers are gentler on hair, help to seal each strand and also add ample shine.

Wrap It Up
If you're in a humid climate, be sure to protect your style with a plastic shower cap or hair wrap when possible.

Overnight Updo
To wake up with your style intact, pull your locks back (gently) into a loose bun or ponytail. Just be sure not to deflate the top of your crown if you crave volume, and opt for a satin pillowcase if available.

Lift Your Roots
Refresh your style by spraying a dry shampoo — like Klorane Extra Gentle Dry Shampoo with Oat Extract ($18, Sephora.com) — at the root each morning. (A light-hold hairspray is also effective at adding volume to unwashed tresses, but may dehydrate dry, coarse or color-treated hair.)

The Right Stuff
If you're creating your hairstyle at home, professional tools can make all the difference. High-quality heated styling tools are a must, and if in doubt, opt for a round brush when styling. It's versatile, easy-to-use and (for the most part) inexpensive.

To know them is to love them. These five cult classics top my list:

Klorane Gentle Dry Shampoo
An effective, powder-based cleanser that rids hair of excess oil and buildup, leaving it feeling full of volume and texture. Use this product to extend the life of a blowout, after the gym, or whenever your locks could use a little pick-me-up.

Bumble & bumble Brilliantine
This creamy hair polish gives hair that slept-in, sexy look with loads of shine. For a tousled effect, run a small amount of Brilliantine through damp hair, or use a comb to achieve a sleeker style.

Aveda Shampure Shampoo
A gentle, aromatherapeutic shampoo that helps to balance and fortify your tresses. Ideal for all hair types.

L'Oreal Elnett Hairspray
A favorite for decades, this strong-hold hairspray adds body and shine, and secures your style without stiffness or flaking.

John Frieda Frizz-Ease Hair Serum
The original frizz-fighter, this old-school serum still does the trick. Use this product on wet or towel-dried hair for an all-over sheen, or apply a pea-sized portion to the ends of dry hair to smooth and separate.
