While cold air can be drying, and sap hair of its moisture and volume, winter is actually the best hair season for those with thick strands — no humidity to mess with your frizz-prone mane. In general, Irion says girls with full strands should stay far away from alcohol-based products — they can be super-drying on your texture, and leave your locks looking dull.
Instead, try products with a light silicone that are emollient and give shine and control. He likes Loma Peratin's Fortifying Repair Serum because it's "like fabric softener for the hair. This is one of the lightest silicone products on the market. What makes it special is the fact that they have infused pear protein in it, so not only does it cut the frizz and leave incredible shine, it also conditions and moisturizes at the same time." Apply it from roots to tips, or, if you have fine hair, Irion says you can also get the same benefits by applying it from mid-length to ends.
Loma Pearatin Fortifying Repair Serum, $34.95, available at Amazon.
