How cutting hair causes faster growth?

Question

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.

Answer 1

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

Answer 2

considering the fact that hair is basically lifeless keratinized cells, it has no nerves to tell the physique to strengthen extra of it, as a result once you chop back hair, the physique does no longer comprehend that this is been cut back, it grows regardless no count if it somewhat is shaven or complete, you in ordinary terms observe when you shave because of the fact it exchange into gentle in the previous and now you spot hairs popping out while in the previous you are able to desire to no longer tell if it has grown because of the fact it appears like each and every of the hairs around it, yet slicing your hair does no longer make it strengthen any speedier, this is a actuality.
