After spending a few days in the heat during a work trip in Palm Beach followed by a few days in the freezing temps in NYC, my skin was confused to say the least, going from oily to dry. But my facial skin wasn’t the only place that suffered from the quick climate change. During my weekly blowout, I noticed my scalp (yes, it’s skin, too) was freaking out (and by freaking out, I mean flaking—gross, I know), too. So I reached for Clear Scalp & Hair Beauty Therapy Deep Nourishing Treatment Mask ($6, drugstore.com) in hopes of nipping the flakes in the bud. I also called up the brand’s celebrity dermatologist, Francesca Fusco, for tips on fighting and preventing flakes. She said that when applying shampoo and conditioner, to lightly massage the product in with my fingertips—not nails, a mistake some women and stylists make. She also said that instead of skipping conditioner at my roots to increase volume (a trick I always do!), to slather it on my roots directly, assuring me that my scalp was craving moisture and that the conditioners were light enough that they wouldn’t weigh down my blowout. Guess what? A few days after taking the advice, my flakes were gone (such a relief) and my hair was bouncy despite applying the mask from roots to ends.
