It may affect very young people and they may lose all their hair, and I have at least two patients with miocencia who are bald in this way, and this type of baldness is believed to be auto-immune, so I think that one could, perhaps, jokingly suggest that Samson may also have had alopecia and it wasn't Delila who cut off his hair, but his auto-antibodies that destroyed the hair making process, and all that makes poor Delila something of a victim of history and perhaps we should be springing to her defence.
