Your Hair Feels Dry, So You Overcondition

Heavy moisturizing ingredients (like oil and silicone) combined with humidity can make your hair look dirty, says New York City hairstylist Ted Gibson.

Be judicious with treatment oils, serums, and shine sprays, which usually contain the most oil-based ingredients.
