Hair belongs to the integumentary system that develops from the ectoderm and thus it has the same embryological origin as the nervous system. Therefore it shares the same characteristics as the neurons when it comes to sensation.

The root/bulb of the hair is the only part of the hair that is alive. meaning it is able to self-regulate and self-replicate. It feeds from the blood vessels that bring information and nutrients from the systemic microcirculation which is subcutaneous through the papilla.

The hair and its bulb are in fact an antenna that is constantly sensing and thus detecting environmental signals emanating from the micro and macro environment. So much so, that within the pilosebaceous unit there is a muscle called the arrector pili muscle, which are small muscles attached to hair follicles and are the smallest muscles in the body.

This is the muscle that works as much as the cardiac muscle, since it is constantly sensing not just changes in temperature and atmospheric pressure, but vibration through resonance, and frequencies from the ecosystem and the surrounding area. The arrector pili muscle, along with the hair root bulb, were over-looked until recently as important environmental sensors - even though the hair has been accepted as an excellent bio marker.

The arrector pili muscle reacts instantly to a systems shock and fear, causing the hair to ‘stand on end’. The arrector pili muscle also relaxes when the system is calm. in addition its ‘sensing’ abilities have also been associated with the forewarning of impending danger. the arrector pili muscle also expands and contracts when the system is over heated or cooled. Therefore the root bulb stores the epigenetic resonance information as it is connected to the arrector pili muscle.
