- an acquired hair-shaft deformity associated with hairdressing procedures (hairdryers, hot tongs, straightening irons etc), which employ great heat.
Microscopical examination of the hair-shaft reveals numbers of bubble-like lesions which are actually gas filled cavities created by the rapid vaporization of moisture within the hair-shaft.
The degree of bubbling therefore increases with higher levels of moisture content.
All hair will react this way to intense heat.
The structure of the hair-shaft will be weakened by bubbling and fragility will result.
There is no way of repairing hair-shafts damaged in this way.
Treatment: Prevention through avoiding the cause.
