The Sticky Situation:
Warmer days go right to your head—by the time you get to the office, your hairstyle has tripled in size.

1. Take control in the shower. Use a moisturizing shampoo and conditioner formulated with silicone—look for dimethicone on the ingredients list—which will help seal the hair’s cuticle (outer layer), blocking frizz-inducing moisture, says Dove celebrity stylist Mark Townsend. (We like L’Oréal Paris EverCreme Deep Nourish Shampoo and Conditioner, $8 each; drugstores.)

2. Trade your standard terry-cloth towel for a microfiber one or a cotton T-shirt for less friction. The best drying technique: Blot or squeeze wet hair, starting at the roots and moving down the strands. Don’t rub or twist—that roughs up the cuticle, causing frizz.

3. Put on a protective coat. While hair is still wet, apply a smoothing leave-in serum or cream all over (like Garnier Fructis Moisture Lock 10-in-1 Rescue Leave-In Spray, $6; drugstores). In addition to dimethicone, look for hydrating coconut, macadamia, or almond oil. “You want to fight frizz from root to tip, so it’s important that the product is evenly distributed,” says Townsend. “Flip your head upside down, work the serum or cream through your hair, and finish by brushing or combing.”

4. If blow-drying, use a dryer with an ionic setting, which reduces frizz, and aim the nozzle downward.

5. For extra polish, tame flyaways at the part, the hairline, and the nape of the neck. Lightly mist a toothbrush with strong-hold hairspray (try Dove Extra Hold Hairspray, $4; drugstores) and gently smooth any problem areas.
