Into Thin Hair

I’m blessed with fairly thick tresses, but the fact that my shower drain has been getting clogged on a daily basis made me want to investigate New York megadermatologist Dr. Dennis Gross’s Skincare Root Resilience Clinical Haircare Collection ($38–$54, sephora.com). My favorite is his Anti-Aging Scalp Serum. With copper peptides to strengthen strands and retinol to exfoliate the scalp, it’s designed to stave off age-related thinning. Bonus: It also works as a pre-blow-dry smoother.
