First of all, hair transplantation is the only effective and proven method to solve male alopecia.
The pattern for male alopecia is a gradual loss in quantity and a decrease of the follicles’ quality. It is a hereditary disease that can be inherited from the mother or father. Usually, 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 turned into DHT by the enzyme 5-alpha-Reductase in hair follicle cells. The activity of both the enzyme and the hormone are higher 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 effects will add up and leave the top of the head bald.
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 hair transplant procedure works to relocate those “genetically prepared hairs” to the top of the head. The hair is transplanted in the area where 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 expanded the scale. In 80% of affected men the development of baldness goes through the seven stages proposed by the scale.
The Hamilton-Norwood scale enables a scientific and standardized documentation of hair loss. It is useful for the development of preventive therapies and for hair transplants.
Capillary graft general principle
It is necessary 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 are gone, they do not grow again.
However, hair loss is treatable, and currently the results are very favourable. According to your hair loss pattern, the doctor can recommend tailored treatment plans to suit your needs. These may include hair transplant surgery, medication, or a combination of both techniques.
Mild hair loss (type 1 and 2)
If the hair loss is recent and men are under 30, hair transplantation is not recommended until the hair loss has decreased or completely stopped. These men can often successfully use alternative medical treatment to decrease or stop the hair loss.
If the hair loss has stabilized for at least 6 months, the hair graft will be a recommended technique for you.
Normal Hair Loss (type 2,3,4 and 5)
The capillary graft is the best solution for your situation. Usually 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 hair is genetically prepared so as not to be rejected and endure throughout the patient’s life.
Severe Hair Loss (types 6, 7)
If the patient’s desire and expectations are realistic, the capillary graft can be performed with very favourable results.
A mega-session with more than 3 000 grafts (3 000 to 4 000 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.
