What are the causes of hair loss in women?DHI Mexico2018-02-14T19:50:03+00:00

In both women and men, the most likely cause of hair loss is Androgenetic Alopecia.

Some others may be:

  • Diseases, such as ChronicTelogenEffluvium (gradual hair loss)
  • Postmenopause(in women over 40)
  • Pregnancy: the massive production of the hormone estrogen causes the follicles to enter their “growth phase”. After giving birth, the hormonal balance is restored and the follicles move to the “loss phase”, causing a large amount of hair to fall all at once.
What are the most common causes of baldness in men?DHI Mexico2018-02-14T19:56:25+00:00

The most common cause of hair loss in men is “Androgenetic alopecia”, also known as “male pattern baldness”.

Androgenetic Alopecia is due to the male hormone dihydrotestosterone (DHT) that acts on the follicles making them progressively smaller until they eventually disappear. This process is called “miniaturization”.

Some other causes include:

  • Stress
  • Bacteria on the scalp
  • Bad nutrition
  • Hormonal imbalance
  • Injuries
  • High fevers caused by diseases (eg, malaria)
Why is DHI Mexico a good choice?DHI Mexico2022-05-31T00:43:01+00:00

DHI Mexico is a branch of DHI Global Medical Group –which has over 70 clinics in over 35 countries and 49 years of experience in hair restoration.  All of the doctors in DHI around the world have been trained and certified by the London Hair Restoration Academy and are continually audited by the medical board.  The DHI clinics follow the same standardized safety protocols during the procedures, which  translates into consistent results and patient satisfaction.

The FUE/DHI technique allows our DHI-certified doctors to extract each graft individually and then implant them one by one in the affected area. In order to do so, we use our own patented tip implanter with which we can offer consistent results. This technique does not require incisions or leave scars and the results are for a lifetime.

Does any other clinic or doctor use the same DHI Direct Hair Implantation Technique?DHI Mexico2018-02-14T22:14:44+00:00

No. Currently, the other doctors and clinics in the region practice the FUT technique or the FUE technique. Direct Hair Implantation is an advanced technique that can only be performed by specialists certified by the Hair Restoration Academy of DHI.

What is the hair made of?DHI Mexico2018-02-14T22:25:13+00:00

The hair is composed of:

  • Keratin (a fibrous structural protein)
  • Natural oils or lipids
  • Water

These “ingredients” are arranged in 3 primary structures:

  • Thecuticle (outer layer)
  • Thecortex (inside the hair that consists of bundles of protein filaments)
  • Themarrow (spongy nucleus in the center of the cortex)
What are the hair growth cycles?DHI Mexico2018-02-14T22:26:25+00:00

The hair growth cycle has 3 stages:

  1. Anagen: Growth period of a hair follicle that typically lasts about 3 to 5 years.
  2. Catagen: At the end of the growth period, the follicles are prepared for the resting phase. This stage of the hair growth cycle usually lasts 1 to 2 weeks.
  3. Telogen: Rest period of the follicle that normally lasts from 3 to 4 months. At the end of this period many hairs will end their life cycle and fall, letting the new ones begin to grow.
What is the average percentage of hair in each growth cycle?DHI Mexico2018-02-14T23:38:29+00:00

The percentage of hair growth in each cycle is:

  • Telogen: 10 – 15%
  • Anagen: 85-90%
  • Catagen: <1%
How many hairs do we spill per day?DHI Mexico2018-02-14T23:39:31+00:00

On average, we stripped 100 hair per day.

What are the types of alopecia?DHI Mexico2018-02-14T23:41:27+00:00

The different types of alopecia are:

  1. Androgeneticalopecia
  2. Alopeciaareata
  3. Tractionalalopecia
  4. Cicatricialalopecia
  5. Trichotillomania
  6. Trapeze alopecia
  7. Telogeniceffluvium
  8. Anagenhair syndrome
What is the diameter of healthy hair?DHI Mexico2018-02-14T23:42:22+00:00

The average diameter of healthy hair is 40-120 microns (1 micron = millionth of a meter).

How much does the hair grow?DHI Mexico2018-02-14T23:43:44+00:00

On average, human hair grows 1 / 3mm per day and 10-15cm per year.

Why do people have different types of natural hair color?DHI Mexico2018-02-14T23:44:39+00:00

The hair color is due to the pigmentation of the hair follicles by two types of melanin:

  1. Eumelanin- pigment that gives Black or Brown color
  2. Pheomelanin- pigment that gives red color to hair
Why does hair turn gray / white with age?DHI Mexico2018-02-14T23:47:01+00:00

With the reduction of eumelanin and pheomelanin, the melanin that causes pigmentation in the hair, the hair turns gray. Likewise, the loss of melanin causes the hair to turn white.

What is the average number of follicles per cm2 in adults?DHI Mexico2018-02-14T23:47:56+00:00

On average, adults have the following numbers of follicles per cm2:

  • 20 to 30 years – 615 follicles / cm2
  • 30 to 50 years – 485 follicles / cm2
  • 80 to 90 years – 435 follicles / cm2
Is hair quality and growth rate the same for everyone?DHI Mexico2018-02-14T23:49:03+00:00

No. There are ethnic, cultural and geographical aspects that cause variations in the quality and rate of hair growth.

How strong is a human hair?DHI Mexico2018-02-14T23:49:55+00:00

The hair is strong like an iron wire. It breaks after applying a force equivalent to 60kg, only after it is stretched around 70%. A single filament can support 100 grams of weight.

How many hairs can grow in each follicle?DHI Mexico2018-02-14T23:51:04+00:00

For each follicle, up to 7 hairs can grow simultaneously.

Shaving the hair increases its thickness?DHI Mexico2018-02-14T23:52:01+00:00

Shaving hair does not increase its thickness or its quality. At the beginning it may be perceived thicker in the roots, but as it grows, it will look the same as before.

What are the hormonal effects on hair loss?DHI Mexico2018-02-14T23:53:33+00:00
  • Thyroid hormones affect hair growth
  • Estrogen in men decreases hair growth
  • Androgens (male hormones) play the most important role in hair growth in men
What is the production rate of hair on the scalp?DHI Mexico2018-02-14T23:55:13+00:00

The hair shaft increases 0.35mm / day and approximately 1cm per month.

What is fine hair?DHI Mexico2018-02-14T23:56:19+00:00

Fine hair, also known as hair “fluff” in the urban dictionary, are thin, short, lightly colored or translucent hairs that develop from childhood and are found anywhere on the body. These usually do not have a size greater than 2 mm, and their follicles are not associated with the sebaceous glands. The growth of fine hair is not affected by hormones.

Is there any difference between the survival of gray hair and black hair?DHI Mexico2018-02-14T23:57:09+00:00

No. Both gray and black hair can be transplanted and will grow naturally.
