I too would like to know if anyone has any winter quick-fixes!

I oil my hair more in the winter.  A bit of jojoba oil on the length, then braid for bed.  This helps replenish the oils lost to the cold, dry air.

I was so sad because I figured out exactly what worked in the summer for my hair but it doesn't work in winter.  I've found that I need to leave in some conditioner (i.e., not wash it all out, I don't like leave-ins as they're too light for my hair) or use a gel, which I don't do in the summer.  I also almost never wear it down as to do so I have to wet it all the way through in the morning and it's just too cold.

Wear a scarf, hat or cap to protect your hair from the cold and wind, but make sure that it's not so tight that it will restrict circulation in your scalp,Use a conditioner daily,Once you have your hair moist, lock in the moisture by running your hair through cold water, this will also give your hair an extra shine,Avoid taking hot showers or washing your hair in hot water, use warm or cool water instead, the heat can dry out and/or damage your hair and skin,Try using a dry shampoo if you need to wash out your hair, one dry shampoo you can use is baby powder, simply sprinkle some onto your hair and use a comb to comb it off.
