Solve this by adding a POSITIVE charge to your hair or hair brush to neutralize the negative charge.
To begin use a shampoo that is less deep cleansing with a PH between 4.5 & 5.5 which is less drying to both hair and scalp.
Conditioners are the real KEY they are Positively charged either rinse out or leave-in your choice. Another option lightly spray your leave-in conditioner on hands and work through your hair or brush or both. This is an instant fix.

Use a hair dryer with a lower heat setting in the colder weather.
Using a micro weave towel prior to blow drying reduces drying time, need for excessive heat, preventing static.
Keep it simple hair generally has a negative charge and conditioners and styling products have a Positive charge which cancels out any charge.
