Black maca for inner hair architecture

Hair weathering is the term given to the deterioration of the hair shaft as a result of cosmetic and environmental factors. In weathered hair, structural damage to the hair fibre causes the cuticle to become unstructured and porous, exposing the cortex to further damage.

Among these factors are environmental pollutants such as UV radiation, smog, cigarette smoke, chemical cosmetic procedures, etc. These generate free radicals and reactive oxygen species (ROS), molecules that oxidise and degrade the proteins and lipids of the hair surface

Physical stress, such as combing, blow drying or excessive heat from strengthening or curling irons, dehydrates and degrades the proteins of the hair surface. Moreover, drastic procedures like perming, relaxing and bleaching cause structural and chemical damage, and are also a source of free radicals and ROS. Daily weathering is also a minor cause of hair loss and a common cause of frazzled and frizzy, hard-to-manage hair.
