Can
collagen build up strangle hair follicles and cause pattern baldness
L'Oréal have made the claim that pattern baldness is caused,
at least in part, by the build up of collagen around hair follicles.
They suggest the collagen build up literally chokes the hair follicle
by shutting off the blood supply and reducing the total size of
the follicle.
However, there are very few dermatologists who would agree with
this hypothesis. L'Oréal has never provided any evidence
that collagen build up causes hair loss. All hair follicles are
contained within a collagen lattice. It helps provide support to
the hair follicle structure. There is no indication that the collagen
around the hair follicle becomes significantly thicker during the
development of pattern baldness. Most dermatologists would suggest
that any thickening of the collagen component is a symptom of pattern
baldness rather than the cause of it.
