Hypotrichosis- What is Hypotrichosis? Types, Causes, and Symptoms

Hypertrichosis is a unique and unusual situation. It lets extreme hair grow anywhere on a person’s body. Hypertrichosis is, at times, identified as a werewolf condition. Hypertrichosis might be confused with hirsutism. Hirsutism is a more general state that lets women grow harsh hair, as males typically do, such as on their chin.


There are several theories about the origin of hypertrichosis.

Congenital hypertrichosis might run in the family. It appears to be produced by genes that excite hair growth, becoming abnormally active. In most people, the genes that made extensive hair growth in human very early parents are sluggish. People do not require hair to stay warm.
In persons with congenital hypertrichosis, these hormones get reactivated in the womb. There is still no reason known for this.

However, which occurs later in a person’s life, has several possible reasons. Causes involve:

  • malnutrition
  • unhealthy balanced diet or specific eating ailments, such as anorexia nervosa
  • some pills and medicines, such as hair growth drugs, particular immunosuppressants, and androgenic steroids
  • cancer and cell variation
  • autoimmune and contagious diseases concerning the skin

They sometimes have a disorder named porphyria cutanea tarda. It lets the skin be notably sensitive to UV light. This might develop hypertrichosis.


The main sign of hypertrichosis is the look of hair in more necessary strength than is normal for a person’s age, race, and sex. hair might also seem in unusual states.

Not all hair created by hypertrichosis is the same. Hypertrichosis can form three distinct kinds of hair:


Lanugo’s hair is long, thin, and very tender. It is related to the hair in the shape of a newborn baby. Lanugo hair will usually have no color and usually drop out some weeks after delivery. In an individual with hypertrichosis, this lanugo hair will persist until it is treated.


Vellus hair is normally short, soft, and slightly colored. These hairs might seem all over the body except in issues with no hair follicles, such as the mucous layers, the steps of the feet, and the palms of the hands.


Terminal hairs are the most secret of the three kinds of hair. It is ordinarily dense, rough, and long. It is often linked with hormones and is usually seen on the face, armpits, and groin.
Females with hirsutism will usually form terminal hair on the face, back, arms, and bosom.

The rigor of its signs might raise or lower with age.


There are several kinds of hypertrichosis, classified according to how and when a person builds the state.

Congenital Hypertrichosis lanuginosa

The fine lanugo hairs seem in an embryo as usual but do not fade away after birth. Instead, the hairs remain to grow extremely in various body areas when the person’s life.

Congenital Hypertrichosis Terminalis

Instead of being born with lanugo or vellus hair, the baby might have final hair at birth that develops during their life. Affected people often have dense, fully pigmented hair that includes their body, holding the face.

Acquired Hypertrichosis

Accrued hypertrichosis occurs later in life. It follows several of the same patterns of congenital hypertrichosis. Hair might be lanugo, vellus, or terminal Hair, and it can seem in tiny spots or over the entire body.

Naevoid Hypertrichosis

Extreme hair growth is seen on one or more spots of skin. A common cause is a very solid and thick monobrow, also recognized as a unibrow.


Hirsutism is a term that relates to females who develop rough terminal hairs in a regular male hair-growth scattering pattern, such as on the chin and chest. Generally mistaken for hypertrichosis, hirsutism strikes up to 10 percent of females. Women usually form hirsutism due to a hormone disproportion.


Some people may be able to lessen their risk of forming some kinds of acquired hypertrichosis by bypassing:

  • at some immunosuppressants
  • androgenic steroids
  • hair growth pills

There is no recognized cure for congenital hypertrichosis. Treatment includes controlling the signs by extracting the hair from the injured area.

Short-term ways of hair removal hold:

  • shaving
  • plucking
  • waxing
  • bleaching
  • chemical epilation

Temporary solutions such as these can reduce the look of hair in the region, but the state will let the hair grow back. Using these techniques can also hurt the skin and let rashes or ingrown hairs. It is also hard to use some of these methods in some areas of the body.

Electrolysis or laser treatment

Some persons might choose long-term ways, such as laser epilation or electrolysis. Electrolysis damages the single hair follicles using electrical charges. Laser epilation does the very using laser light and is usually less grievous than electrolysis. The procedure will occur in permanent hair loss for some people, though it might take many sessions to obtain the aspired effect.


Relying on the kind, hypertrichosis is usually followed by other signs and linked to an underlying state.
There might be a genetic factor to some kinds of hypertrichosis, so anyone with a family history of the state might wish to talk to a doctor.
Handling the signs or treating the underlying problem is the only constant and promptly available method for hypertrichosis.
