First of all start by remarking that the hair graft is the only effective and proven method to solve male alopecia.
The pattern of male alopecia is a gradual loss of the quantity and decrease in the quality of the follicles. It is a hereditary disease that can be inherited from the mother or father.Normally, the implantation line recedes and there is a decrease and thinning of the crown.
Androgenic alopecia is caused by the effects of the male hormone dihydrotestosterone (DHT: a derivative of testosterone) on the hair follicles of the genetically susceptible scalp, which are located in the front, upper and crown areas of the scalp.
Testosterone is converted to DHT by the enzyme 5-alpha-reductase in hair follicle cells. The activity of both the enzyme and the hormone are increased in the areas where hair loss occurs.
Men’s hair loss is progressive throughout their lives. The effects tend to be exhibited in 2 main areas: Entries and thinning of the crown. Over time these will join until the top of the bald head is left.
However, on the back and sides of the head, the hair follicles are immune to the effects of DHT and therefore the hair is programmed to grow throughout life .
A capillary graft procedure works to relocate those “genetically prepared hairs” to the top of the head, that is, the hairs are repositioned in the area that the patient needs them.
The Norwood scale
The Hamilton-Norwood scale (often abbreviated NW) classifies the states of male androgenic alopecia in seven levels (from I to VII). This classification was developed in 1951 by Dr. James Hamilton.
In 1975, Dr. O’Tar Norwood modified and enlarged the scale. In 80% of affected men the development of baldness goes through the seven proposed stages.
The Hamilton-Norwood scale enables scientific and standardized documentation of hair loss. It is useful for the development of preventive therapies and for hair transplants
General Principles of Hair Injection
It is important to understand that hair loss in men is a progressive and irreversible process. We are born with a finite number of hair follicles and once they stop occurring, they do not return to resume.
However, hair loss is treatable, and currently the results are very favorable. According to your hair loss pattern, the doctor can recommend tailored treatment plans to suit your needs.These can include surgery by capillary grafts, medication or a combination of both techniques.
Mild hair loss (type 1 and 2)
If hair loss is recent and men are under 30 years of age, hair transplantation is not recommended until the rate of detachment has decreased or stopped completely. These men can often successfully use alternative medical treatment to decrease or stop the process of hair loss.
If the hair loss has stabilized for at least 6 months, the hair graft will be a recommended technique for you.
Losses of Hair (type 2,3,4 and 5)
The capillary graft is the best solution against your problem .Normally we can solve it in a single session although in some cases you may need an extra reinforcement session.
As we have mentioned on several occasions implanted hairs are genetically prepared so as not to be rejected and endure throughout the patient’s life.
Severe Hair Loss (types 6, 7)
If the desire and expectations of the person are realistic, the capillary graft can be performed with very favorable results.
A mega-session with more than 3000 grafts (3000 to 4000) grafts usually covers the anterior and superior areas of the scalp. To increase the density and to cover the crown and the back areas of the scalp, 2 or 3 sessions may be performed depending on the case.
