Blow-dry Japanese Straightened HairQ: Is there a need to blow-dry Japanese Straightened Hair? If I let it air dry, will it dry straight?
A: According to the after-care instructions for the Japanese straightening processes (Thermal Reconditioning) the hair's cuticle layer is more tightly sealed as a result of the straightening process, making it more resistant to moisture. This means that less moisture is absorbed into the hair shaft and that the hair dries more quickly with less damage.
You don't "have" to blow dry your Thermal Reconditioned hair to maintain a straight look, and many women report that their straightened hair now dries in less than half the time it previously did. And in those times when you need to have your hair completely dry after thermal straightening, women report that their hair blow-dries in a fraction of the time it did previously.
