Androgenetic alopecia — A genetic and increased receptivity of the scalp to androgens, which explains 95% of masculine hair loss cases.
Androgenetic alopecia, the most common form of male baldness, is often genetic — a family history can be traced from the parents, grand- parents, uncles or aunts. This form of baldness is attributed to an increased receptivity of the scalp to androgens (testosterone), the male sex hormones.
Testosterone combines with the 5-alpha reductase enzyme, located in the scalp, to create DHT. When the concentration of DHT is very high, the capillary cycle is altered. In more susceptible areas, such as the temples and the top of the head (vertex), DHT acts on the hair follicles by shortening the growth phase of the hair and by progressively shrinking the follicles, which will result in the growth of very fine hair. In the end, hair growth will completely stop in these areas, and the inactive hair follicles will sink in the dermis, leaving the skin completely smooth. Androgenetic alopecia usually starts after puberty, most often in the mid-twenties, and progresses until 55-60 years old, with more active phases and dormant phases. These days, it is not rare to see this progression sped up by aggravating factors such as stress, dietary additives and polymers found in hairstyling products. In men, androgenetic hair loss is progressive and it follows a predictable pattern. Hair loss begins on the temporal lobes (the hair line) and then the top of the head is affected. Both regions will eventually reach one another to create a complete baldness of the crown.
Seborrheic hypersecretion — an imbalance of the sebaceous glands that causes progressive thinning of the hair.
Seborrheic hypersecretion will provoke a progressive thinning of the hair — 40% to 50% of the hair count will be lost — but it will not cause baldness like androgenetic alopecia would. It is due to an imbalance of the sebaceous glands of the scalp. They become hyperactive and start secreting an oily coating that suffocates the hair follicles, which will atrophy over time.
Seborrheic hypersecretion will often aggravate androgenetic alopecia.
Other causes — stress, trauma, disease, surgical intervention, infection, some medications, alopecia, etc.
Androgenetic alopecia (Genetic excessive receptivity of the scalp to androgen hormones) : In 80% of cases; hair loss in women is caused by a genetic predisposition to androgens. It is the main cause of hair thinning and hair loss among women. At the onset of menopause, 40% of women will experience a certain degree of androgenetic alopecia.
Androgens are hormones that normally flow in the blood, just like the feminine hormones estrogen and progesterone. If you are genetically predisposed, the androgens will have a negative influence on your hair follicles, which will translate into a thinning of the hair and an acceleration of its lifecycle. Androgenetic hair loss is progressive and always causes thinning hair. It is sometimes accompanied by hyperseborrhea.
Women who suffer from androgenetic alopecia will have a tendency to lose their hair in a combination of various patterns and progressions. Some women notice their hair loss beginning in the anterior or midscalp region a few inches behind the hairline. For other women, it is the hairline itself that begins to thin, but there is rarely a true recession as there is with men – instead, the thinning seems to occur randomly throughout the first inch or so of the hair without the orderly recession pattern that is characteristic of most male¬pattern baldness.
- Hormonal changes (pregnancy, pre¬menopause, menopause)
- Stress, anxiety, emotional shock
- Vitamin or dietary deficiencies (iron, calcium)
- Chemotherapy and Radiation treatments
- Autoimmune reaction (alopecia areata, totalis or universalis)
- Sebaceous gland imbalance
In cases involving chemotherapy, pregnancy, vitamin deficiency, stress, seborrheic hypersecretion, etc — it can be possible to stabilize hair thinning and hair loss and even stimulate regrowth. It is important to take action on the cause of the problem by adopting a targeted scalp treatment program.
If the woman presents a strong excessive receptivity of the scalp to androgens (androgenetic alopecia), it can be possible to limit their effects by adopting a targeted treatment plan. However, to regain the desired hair density, the woman has many options, such as wearing a partial or total hair prosthesis, or undergoing a hair transplant procedure.
Unfortunately, for some women hair loss will be irreversible. For example; certain alopecia cases, after scalp burns, in the presence of scars or following a serious infection. In these cases, excellent corrective measures exist to help women get back a full head of hair.

The health of your hair is linked to the health of your scalp: you can’t have healthy hair if your scalp isn’t healthy. The scalp is actually a skin base from where your hair follicles grow. When an ailment is present the treatment should be in the realm of dermatology and trichology, rather than hair styling products, which in turn, are aimed at the health of the hair shaft.
Therefore, trichology is the science at the crossroads of dermatology and cosmetology that aims to bring back the hair cycle to its normal state.
This is why at Capilia, our specialists are trained in trichology. We start from the root of the problem. After an analysis of your scalp, we will recommend a program specifically designed to restore the balance of your scalp, combining home care treatments with in-depth salon treatments.
