@ everyone — Nice links guys, thanks.
@ Hellhouser — I'm asking myself the same 4 questions.
@ Princessrambo — This hair growth of adult hair on the arm of a 6 year old boy is so weird. I imagine it's something that dates back to the time when as pre-humans we were born with adult fur to protect us from cold and rain, and not as hairless human babies. When a wound occurs the genome engages the old pre-human program of skin healing, hence the adult hair. Just my guess.
To get back to Hellhouser's questioning, I can imagine that at some point the healing process ends, the genes involved in healing don't process any hair neogenesis and follicles that were born this way continue their life only if the local context makes it possible. The adult hair on the 6 year old boy, being in a hormonal context not favourable to adult hair growth, disappeared (right?), but brand new follicles on a very gradually repaired scalp could live for years, why not? It could well be a gradual start over of our scalp, who knows? :woot:
