Types of hair growth found on the body

Hair is found all over the body except for the palms of the hands, the soles of the feet, lips and external genitalia. There are three different classifications:

• Lanugo

• Vellus

• Terminal

• Clare Hargreaves-Norris

Lanugo

Lanugo is the hair found on an unborn baby and the first result of cellular activity within the skin. This is usually discarded before or soon after birth and replaced by slightly coarser hair.

• Clare Hargreaves-Norris

Vellus

Vellus is the soft downy hair often found on the cheeks and all over the body. The hairs usually lack pigmentation and grow from a shallow depth at about sebaceous gland level. These hairs rarely grow longer than 2 cm in length and are usually straight due to the fact that they have shallow follicles.

Vellus hairs do not become terminal unless they are stimulated by a topical (i.e. shaving or plucking) or systemic (i.e. hormones, medication) cause. If this occurred they would then start to grow deeper, develop a bulb, pick up a blood supply from the dermis and become a shallow terminal hair.

• Clare Hargreaves-Norris

Terminal

Terminal hairs are pigmented, deep seated, coarse hairs, which have a well-developed root and bulb and often extend into the subcutaneous layer. Terminal hairs are present on the scalp, eyebrows, underarms, pubic areas, legs, men’s chests etc. A terminal hair is comprised of three layers: the cuticle, cortex and medulla.
