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.
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:
- Bacteria on the scalp
- Bad nutrition
- Hormonal imbalance
- High fevers caused by diseases (eg, malaria)
In 2002, DHI Global Medical Group introduced to the world of hair transplantation the procedure currently known as Follicular Unit Extraction (FUE), which left the Strip Technique (FUT) obsolete at that time. In 2008, the evolution of the FUE developed the DHI Direct Hair Implantation, surpassing its predecessor in all aspects with better results.
Our mission is to offer our customers the best existing treatment. In our early years, it took a doctor about 10 hours to extract 500 follicles and 1000 hairs. Through our dedication and commitment, the teaching efforts of the DHI Academy and our advanced patented technology, we have made important advances in hair restoration. Today, we are able to extract and place 4,000 hairs in 7 hours and 6,000 in a two-day session.
The increase in the quality of our work, and the sustainable growth of the company worldwide, is due in part to the fact that we use our own patented instruments, and to the effort we dedicate to the DHI Academy and its strict educational protocols. Our medical and administrative team is the largest and most experienced worldwide. DHI Global Medical Group has trained more than 150 medical specialists, which allows us to practice our techniques in more than 60 clinics and 25 countries.
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.
The hair is composed of:
- Keratin (a fibrous structural protein)
- Natural oils or lipids
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)
The hair growth cycle has 3 stages:
- Anagen: Growth period of a hair follicle that typically lasts about 3 to 5 years.
- 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.
- 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.
The percentage of hair growth in each cycle is:
- Telogen: 10 – 15%
- Anagen: 85-90%
- Catagen: <1%
On average, we stripped 100 hair per day.
The different types of alopecia are:
- Trapeze alopecia
- Anagenhair syndrome
The average diameter of healthy hair is 40-120 microns (1 micron = millionth of a meter).
On average, human hair grows 1 / 3mm per day and 10-15cm per year.
The hair color is due to the pigmentation of the hair follicles by two types of melanin:
- Eumelanin- pigment that gives Black or Brown color
- Pheomelanin- pigment that gives red color to hair
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.
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
No. There are ethnic, cultural and geographical aspects that cause variations in the quality and rate of hair growth.
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.
For each follicle, up to 7 hairs can grow simultaneously.
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.
- Thyroid hormones affect hair growth
- Estrogen in men decreases hair growth
- Androgens (male hormones) play the most important role in hair growth in men
The hair shaft increases 0.35mm / day and approximately 1cm per month.
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.
No. Both gray and black hair can be transplanted and will grow naturally.
