We're sure you've noticed how much better your hair looks and feels during the summer than the winter. Blame the polar vortex for sucking you terrific tresses dry!

While it's true that the warm weather promotes hair growth, treating your hair right and focusing on scalp health and nutrition is sure to bring results no matter the weather.

To optimize your hair growth during any time or season, try these pro tips from board-certified dermatologist Dr. Nussbaum:

Start With A Trim. Chopping your split ends will ensure less hair breakage, which can cause hair to look thinner at the ends and appear shorter. You want to start with fresh ends to see the fastest results.

Stay Hydrated. Water is essential to not only our bodies, but for promoting hair growth scalp health. Constant dehydration can drain moisture from the hair roots and result in hair loss.

Wear Up Dos. These styles like sock buns and braids protects your fragile ends from snagging or pulling on your winter scarves and sweaters. Get creative with your look! But try this tip with caution. Don't wear your hair too tight, as it will damage the perimeter of your hair and cause your edges to thin.
