Cold, Wet Air can cause hair to dry out and become brittle. It can also lead to static curly strands, so make sure to keep it hydrated and healthy.
Windswept or wind damaged? While hair can have a perfectly tousled effect from the adverse weather conditions we have been seeing recently, when there is too much exposure to those breezy fall days tangles, knots and brittle ends can occur.
Quick fix: Rinse your hair with cold water instead of warm in order to seal the cuticle (it will alo make hair glossy) and then tuck your hair in your sweater until you get in doors, or use a silk scarf as a head wrap.
