How often you should wash your hair in a cold climate depends on your hair's natural greasiness and how comfortable you are with it. You should wash it whenever you feel like it is too greasy.
Freezing cold climate for example the snowy hair has long and fluffy hair to stay warm in the cold brutal winters

Everyday.
the cold air is making the water in your hair cold which makes your hair cold. if your hair is dry then there is no water in i for the hair to be as cold as it is when its wet.
You should wash your hair every week if you have thick hair and you don't always put oils in your hair. UNLESS you have thin hair. You should wash your hair hair every other day!
Most sources recommend that people should wash their hair daily or every 2 days. This is usually because if hair is not washed this often it can begin to look oily or greasy.
If you are straitening your hair but do not want to damage it, then you should use special protention products. Often you'll find specific shampoos dedicated to hair that is often heated (via straitener or blow-dryer), personally I would recomend Tresemme. However you should not straiten your hair too often.
