TOO much heat, cold, dryness or damage to the hair have NEGATIVE charges all create hair static.
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 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.
Hair dryers have a lot of heat and cause dehydration of both hair and scalp resulting in Static choose carefully.
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.
NO CHARGE NO STATIC
