Formula Fkx

Those who are blessed with curly hair owe that fact to the cross-section of our individual strands of hair. Straight hair has a symmetrical, circular cross-section, with no tendency to curve, but a hair with an oval or asymmetrical cross-section will naturally curve about its weaker axis. As such a hair grows, it takes the form of a spring. The tighter the curl, the springier the hair. Waves, curls, coils.

F=kx is the mathematical formula, known as Hooke’s Law, that describes how a spring reacts when a force is applied to it.

Formula F=kx is the perfect name for the formula we’ve developed to achieve and maintain the spring in your curls.
