Hair is made up of Keratin – a fibrous structural protein. Hair also contains natural oils (lipids) and water.

What are the 3 growth cycles of hair?

The growth cycle of hair consists of 3 stages:

Anagen – It is the growing period of a hair follicle that typically lasts about 3 to 5  years.

Catagen – At the end of the growth period, hair follicles prepare themselves for the resting phase. This stage of the hair growth cycle usually lasts about 1 to 2 weeks.

Telogen – This is the resting period of a hair follicle. It is usually 3 to 4 months in length and at the end of this period older hairs that have finished their life will fall out and newer hairs will begin to grow.


What is the average percentage of hair in every growth cycle?

The percentage of hair growth in each cycle is:

Telogen: 10 – 15%

Anagen:  85 – 90%

Catagen: < 1%

What are the causes of hair loss in men?

By far the most common cause of hair loss in men is “Androgenetic Alopecia”also referred to as “male pattern hair loss” or “common” baldness. Androgenic Alopecia is due to the male hormone dihydrotestosterone (DHT) acting on genetically-susceptible scalp hair follicles that causes them to  become progressively smaller and eventually disappear. This process is called “miniaturization.” The other causes can be Stress, scalp bacteria, poor nutrition, hormonal imbalance, injury and high fever (e.g. Malaria)

What are the causes of hair loss in women?

The most common form of hair loss in women, Chronic Telogen Effluvium (long term diffuse hair loss), is an increase in hair loss and decrease in hair thickness over a long period of time.

Why do women lose a lot of hair after pregnancy?

The massive production of the hormone Estrogen during pregnancy puts hair follicles into their ‘growth phase’. After the birth, the hormonal balance is restored and the hair follicles go into the ‘loss phase’, causing a large number of hairs to fall out at once.

Why is hair loss diagnosis required before any treatment?

Hair loss might appear with different patterns and because of several different causes. Here at DHI Global Medical Group we recognize that the correct diagnosis is the basis for successful and permanent treatment. That is why we have developed a very sophisticated diagnostic system for hair loss, the DHI diagnostic system.

What is the DHI diagnostic system?

Here at DHI Global Medical Group we recognize that the correct diagnosis is the basis for successful and permanent treatment. That is why we have developed a very sophisticated diagnostic system for hair loss, the DSA. DSA includes Psychological Aspects, Dermatological Examination, Mathematical Aspects and the DHI Alopecia Test. DSA was developed by a team of world renowned experts to provide accurate and personalized diagnosis for all types of alopecia – hair and scalp disorders. DSA examines each specific case individually, including psychological aspects, dermatological examination, mathematical aspects and the DHI alopecia test; before determining the appropriate treatment plan. A team of DHI experts that include administrative consultant, dermatologist, plastic surgeon, psychologist and endocrinologist are involved in the diagnostic process, according to each patient’s needs. A scientific board compiled of internationally renowned medical experts supervises and approves every treatment plan.

What is the DHI alopecia test?

The DHI alopecia test is part of the DHI diagnostic system. With the help of a micro camera and specific software, it allows our experts to analyze and diagnose the current condition of your hair loss by measuring each hair follicle separately and establishing how many hairs are in Anagen or Telogen phase at the moment. Thereafter the consultant discuss with the patient the hairline design and the distribution of hair on the thinning zones to give the client best possible density and natural results.
