Do I have to use locking mist hair spray every time after I apply THK Hair Building Fibres?

NO. We would only suggest the customer use the locking mist hair spray if the hair is very thin and prone to fly about when conditions are extremely windy. The fibres stay put, not because of the homopolar anions static adsorption effect. We don’t recommend that customers use locking mist hair spray for a long time on account of average locking mist hair spray contains Colophony, Ethyl Alcohol and Essence. These ingredients are not good for the hair.
