Causes of Hair Loss

Hair Loss & Balding

Why do we lose our hair?

The Hair life cycle

The life of an individual hair on your head is around 6-7 years.

Hair on the scalp grows about 0.3 to 0.4 mm per day or about 6 inches per year. Unlike other mammals, human hair growth and shedding is random and not seasonal or cyclical.

In that lifetime the human hair goes through three stages of growth and shedding: anagen, catagen, and telogen:

Anagen is the active phase of the hair. The cells in the root of the hair are dividing rapidly. A new hair is formed and pushes the club hair (a hair that has stopped growing or is no longer in the anagen phase) up the follicle and eventually out. During this phase the hair grows about 1 cm every 28 days.
Scalp hair stays in this active phase of growth for two to six years.

The Catagen phase is a transitional stage and about 3% of all hairs are in this phase at any time. This phase lasts for about two to three weeks. Growth stops and the outer root sheath shrinks and attaches to the root of the hair. This is the formation of what is known as a club hair.

Telogen is the resting phase and usually accounts for 6% to 8% of all hairs. This phase lasts for about 100 days for hairs on the scalp and longer for hairs on the eyebrow, eyelash, arm, and leg. During this phase, the hair follicle is completely at rest and the club hair is completely formed. Pulling out a hair in this phase will reveal a solid, hard, dry, white material at the root. About 25 to 100 telogen hairs are shed normally each day.

Premature Hair loss or balding in men and women

Excessive hair loss and balding occurs in 1 in 2 men and 1 in 3 women. There are many reasons for this! The causes are usually linked to stress, changes in hormones, under nourishment, androgenetics, autoimmune problems, and some relating to psychological problems.

“Alopecia” is a medical term which simply means “hair loss.” Alopecia does not refer to one specific hair loss disease. Androgenetic Alopecia, however, is one cause of hair loss.

Androgenetic alopecia can cause an experience of hair loss as early as teenage years. – For men, this type of balding is typically characterized by hair loss that begins at the temples and crown. The end result may be partial or complete baldness. – Women with androgenetic alopecia usually have hair loss limited to thinning at the front, sides or crown. Complete baldness rarely occurs in women .

The majority of women with androgenic alopecia have diffuse thinning on all areas of the scalp. Men on the other hand, rarely have diffuse thinning, but instead have more distinct patterns of baldness. Some women may have a combination of two pattern types. Androgenic alopecia in women is due to the action of androgens, male hormones that are typically present in only small amounts.

The Most Common Cause of Hair Loss is DHT

How DHT Shrinks and Kills your Hair:

In simple terms:

  1. DHT is formed
  2. DHT attacks the hair follicle
  3. DHT causes the hair follicle to shrivel
  4. DHT causes your hair to die and stops regrowth.

A fuller explanation:
1. Dihydrotestosterone (DHT) is formed when an enzyme, 5 Alpha Reductase (5AR), interacts with testosterone. It converts the testosterone to DHT.
2. Part of the hair follicle is known as the Androgen Receptor. DHT attaches itself to this receptor.
3. The hair follicle is gradually miniaturised because of the presence of the DHT.
4. Eventually if nothing is done to block and stop the DHT, the miniaturised hair follicle eventually dies and hair loss occurs.

What is Trichology?

Trichology is a science of the hair and scalp, this looks into the structure, function and diseases. Hair and scalp problems and disorders can be diagnosed and treated accordingly by a Trichologist.

Many people may think that the hair and scalp are an isolated external feature of the human body, but in actual fact the condition of our lock and skin reflects on the status of our internal bodily functions. The healthier you are the better condition your hair and scalp will be.

A Trichologist deals with problems such as hair loss, different types of balding, scaling conditions, oily scalp problems, and hair breakage or damaged. Each new client would be given a consultation, consisting of obtaining health and medical history, life style, diet, daily hair care habit and other relevant facts relating to their problem. This then enables the Trichologist to diagnose and consider an appropriate treatment, and if a referral to the doctors is necessary.

The Background of Trichology

“In Britain, the Institute of Trichologist was founded in 1902”
“In America, the International Association of Trichologist was founded in 1974”

Both institutes are a non-profit corporation establishment, which promote the study and research of the treatment, health, care and diseases of the human hair and scalp.

In 1973, The Redken Foundation donated a large grant to the University of Southern California to develop a comprehensive educational course in trichology. Between the year of 1974 and 1975 a study course was developed and under the guidance of David Salinger students from all around the world could undertake the study, clinical training and pass the final examination to gain the IAT status.
