Excess hair growth

  1. 1. Clare Hargreaves-Norris Excess Hair Growth NVQ Level 3 Beauty Therapy
  2. 2. Clare Hargreaves-Norris Introduction The human body is covered with hair follicles which can lie dormant or active, and when active may grow vellus or terminal hairs. Hair distribution, the type of hair and the rate at which it grows varies between individuals and also between areas on the body. Hormones control all hair growth, and if the male hormone androgen is over secreted excessive hair growth often occurs. Research has shown that most excess hair growth is due to a combination of excess androgens and the presence of an enzyme in the hair follicle that makes it sensitive to the circulating androgens in the blood stream.
  3. 3. Clare Hargreaves-Norris Superfluous hair growth This is the general term for excessive hair growth. However, superfluous hair is a matter of opinion and cultural preferences, therefore only the client can decide what is excessive for him or her.
  4. 4. Clare Hargreaves-Norris Hirsutism Hirsutism refers to a masculine pattern of hair growth in women; this hair growth pattern is normal to a man. This excessive hair growth is due to an over secretion of androgens, and the hair follicles developing increased sensitivity to the circulating androgens in the blood stream. The dormant hair follicles are stimulated to grow hairs and the existing vellus and terminal hairs grow larger in diameter. There are two stages of hirsutism:  Primary hirsutism occurs at puberty and develops as a response to the androgens circulating within the blood stream.  Secondary hirsutism occurs after puberty and develops because of an endocrine disorder.
  5. 5. Clare Hargreaves-Norris Hypertrichosis Hypertrichosis refers to a generalised overgrowth of vellus or terminal hairs all over the body of either males or females. The hairs grow faster and longer than normal although there is no increase in the diameter (coarseness) of the hair. This type of hair growth is not hormone dependent but due to genetic or racial predisposition.

  7. 7. Three main causes of excess growth In order to achieve a successful treatment, the electrologist must be aware of the cause of the hair growth problem. There are three main causes of excess hair growth: Clare Hargreaves-Norris  Congenital  Topical  Systemic
  8. 8. Clare Hargreaves-Norris Congenital This hair growth is present since birth, some individuals are born with a normal excess of hair growth in a pattern that they inherited. There is a variation in hair growth patterns between races and this is congenital. People vary in their sensitivity to androgens, particularly females who have lower levels of female hormones and therefore often develop superfluous hair growth.
  9. 9. Clare Hargreaves-Norris Topical Due to stimulation or friction in the area, excess hair growth results. Stimulation of the blood supply results in the hair receiving more nourishment, which allows it to grow deeper and coarser; this is also a protection mechanism. Examples of topical stimulation are tweezing, plaster casts chaffing, shaving or x-rays.
  10. 10. Clare Hargreaves-Norris Systemic This can be caused by both normal and abnormal hormonal changes within the body, which stimulates excess hair growth. Examples of normal systemic changes are puberty, pregnancy and menopause. Examples of abnormal hormonal changes due to endocrine disorders are cushings syndrome, and adrenogenital syndrome.
