The new hair makes its way towards the surface and will stay there for about five years. The hair bulb returns to its position and your hair will grow on healthily. In total this cycle will happen about twenty times in a human lifetime. The discovery in the field of hair-loss has relevancy to this phase as is described above. Research has shown that persons who become bald have a thickened hair root.
Hair gets a delicate structure.
Hair does not get any older than a few weeks or months because the hair bulb can not move back. Hair falls out a lot and eventually you will be bald. The thickened hair root prevents the hair bulb from returning back to its place in the skin. Because of this, new hair will be produced, but will not be able to settle. The growth phase will then be disrupted and the hair bulb will continuously produce new hair, which, instead of lasting the normal five years, will only become a few weeks or months old.
