Someone educated in hair science please explain is there any truth to this well known belief? A prievious entry said that there are receptors in hair roots. When hair is cut the tension at the root is less. This triggers hair growth until the predetermined tension level is reached. This is the first time I heard an explanation that sounds possible. Others that say cutting the split ends causes growth means to me that there is just less breakage so hair appears to grow longer. But the "tension sensor" explanation also answers a question I have had as to why a dog's hair only grows so long.
How cutting hair causes faster growth?
it does NOT make your hair grow faster, it just keeps the dry and brittlel ends off that BRAKE OFF so it looks like your hair isn't growing. Your hair grows from the roots, not the other end
