Will shaving often increase my beard growth?
Answer:
Short answer: No! People get this impression because when you shave, the “ends” or points of the hairs become blunt instead of soft. So it feels rougher, but the growth is the same. The hair might look darker but it is only because the length is uniform.
One theory for the origin of the myth that shaving makes a beard grow faster is that humans perceive change by proportion.
For example: going from ';zero'; to half an inch in a month is really noticeable; adding a half an inch to a beard that's already (say) 2 inches long is a much less noticeable change.
In the first case, it's a ';100%'; proportional change, while in the second case, it's only a 25% change. So even if a beard is growing at a constant half an inch per month, it will *seem* to grow faster at the beginning and slow down as it gets longer, because the proportion of change is dropping. Does shaving once make your facial hair thicker?
That's an old myth. What happens is that your newly sprouting facial hair has soft downy ends that get cut off when you first shave, leaving the blunt end of the thicker, darker shaft underneath, so that it looks like your beard is heavier. You only have so many hair follicles and your hair only grows so fast. Shaving doesn't make more follicles or make your hair shafts any thicker or grow any faster. In any case, hair shafts don't have any nerves in them so they have no way of knowing that they've been shaved!
Shaving it only makes it thicker *briefly*, then it reverts to its usual thick/thinness. Unless you shave daily. But yes, puberty gradually thickens it anyway, but (there's always a but) not if your genetics are such that you have fine hair (like mine).
the second thing is true
