While the brand will exit counters at the end of January (sigh), you can still stock up on your favorite Custom Blend base products online — while supplies last — via the Prescriptives Custom Blend Replenishment program.

To take advantage, visit your local Prescriptives Custom Blend counter and ask for a Custom Blend recipe form. Then register your recipe online at Prescriptives.com/CustomBlend and you'll be notified by e-mail when it's available for purchase in January 2010.

To keep our locks looking their best, I've asked Marc Mena of Warren-Tricomi Salon in NYC— who counts the likes of Molly Sims, Rachael Ray, and Anna Paquin as clients— to share his secrets for "summer-proofing" hair:

Get Your Beauty Sleep
Prolong a blowout, or any hairstyle, during the summer by sleeping with silk pillowcases in a well air-conditioned room.

Invest in Silicone
No, not that kind. Use a silicone shampoo to coat and seal the cuticle to prevent humidity from getting into hair. Also, for extra protection, go over hair with cool air once you've finished drying it.

Repair & Protect
be sure to use a weekly conditioning treatment to fight summer dry and unmanageable hair. To get "green" and save a little money, create a simple mask from olive oil, egg yolks and mayonnaise. Mix all together or use separately, and apply directly in to hair. After applying, put a shower cap or plastic bag over the hair to seal in the body’s natural temperature to help activate. Then, rinse out and shampoo.

Seal the Deal
Use anti-humidity hairspray when styling hair. The hairspray helps to shield the hair from humidity. In a hurry? Pull hair into a tight pony tail or bun for a sleek and smooth stylist look.

& If You're a Curly Girl...
After shampooing, apply styling product to each curl, distribute evenly, and be sure to follow your natural twists (never go against the curl). And most importantly—Don't touch hair until it is 100% dry. Once your curls are dry you can separate them and have fun with your hair.
