Bubble hair: a cosmetic abnormality caused by brief, focal heating of damp hair fibres.
Following investigation of two individuals with bubble hair abnormality, a reproducible cause has been established. Simple experiments showed that brief, focal heating of damp hair is sufficient to cause bubbles to form inside the hair fibres. This in turn results in weak, dry and brittle hair which breaks easily.
