Human Hair as defined

Hair is defined as a protein filament that grows through the epidermis from follicles deep within the dermis. Hair can grow on most areas of the human body, except on the palms of the hands and the soles of the feet (among other areas).

* Hair can be divided into three parts length-wise:

• (a) the bulb, a swelling at the hair base which originates from the dermis,

• (b) the root, which is the hair lying beneath the skin surface,

• (c) the shaft, which is the hair above the skin surface.

In cross-section, there are also three parts:

• (a) the medulla, an area in the core which contains loose cells and airspaces

• (b) the cortex, which contains densely packed keratin

• (c) the cuticle, which is a single layer of cells arranged like roof shingles.

* Human scalp hair normally grows at a rate of 0.4 mm /day (incidentally human scalp hair grows at a rate four times that of human nails. Human nails grow at a rate of 0.1 mm/day).

* Emotional distress, especially that caused by verbal abuse, etc. often is a contributing factor to a slower hair growth rate.
