Unfortunately for all the shampoo manufacture's hair is dead.
The follicle producing the hair is alive and produces keratin based protein which is called hair. Nothing you do to the hairy bit, beyond pulling it out or laser or electrolysis will do much to the follicle. Straightening or curling as long as you do not pull the root out has no affect on the follicle. But hair also grows in cycles governed by circadian rhythms, monthly cycles, and seasonal changes.
I wrote my first research paper on circadian rhythm growth of belly hair in mice. Rocked the world.
