The term hair damage is tossed around our industry ubiquitously and haphazardly. It represents a decidedly generic term insinuating that hair properties have been negatively altered in some way, shape or form relative to the initial, freshly grown state. Yet, the causes and materialization of these changes are plentiful. A small sampling of irksome symptoms might include undesirable tactile properties, visual dullness, an increased propensity for breakage and/or an unruly and unmanageable disposition. Possible instigators, on the other hand, might involve grooming-related abrasion and fatiguing, extreme temperatures, environmental battering, chemical treatments and others.
