The atom is the smallest unit of molecular structures. Atoms combine to form molecules. A protein molecule is a chain of smaller units called amino acids.

These amino acids form a spiraling chain called the helix. Seven of these helical coils chemically bond together forming a protofibril. Protofibrils join together to form the microfibril, which are bonded into macrofibrils, and the macrofibrils associate to form the cortical fibrils, or bundles

All these fibers twisting and bonding together create the cortex of the hair, which is protected by the translucent outermost layer of the hair, the cuticle.

The cuticle consists of 7 to 10 layers of cuticle cells. It is the first line of defense against any physical or chemical damage to the hair.

Because of its armor-like structure, the condition of the cuticle has always been of the utmost concern in the formulation of hair care products.

As we discuss the Mastey Hair Color System, we will refer to this basic hair structure section in order to better understand the superior formulation and function of Mastey products.
