Frontal alopecia

Frontal alopecia (alopecia frontalis) is a progressive type of hair loss involving primarily the frontal hairline and the temples. It is most often chronic and may take the form of non-scarring alopecia or – in a particularly clinically significant variant – scarring alopecia, leading to permanent damage to the hair follicles. This condition mainly affects postmenopausal women, although it also occurs in younger patients and in men. The mechanism of the disease is associated with inflammatory, hormonal, and autoimmune processes that disrupt the hair growth cycle and lead to its irreversible loss.

Frontal fibrosing alopecia

Frontal fibrosing alopecia (FFA) is a specific, clinically significant form of frontal alopecia. It belongs to the group of primary scarring alopecias, in which permanent destruction of hair follicles occurs and they are replaced by fibrous tissue.

The disease process is inflammatory and autoimmune in nature. Lymphocytic infiltration occurs around the hair follicle, leading to its degeneration. As a result:

hair stops growing back,
the hairline systematically recedes,
the skin becomes thin, smooth, and devoid of follicular openings.

Characteristic clinical features:

symmetrical recession of the hairline on the forehead,
loss of eyebrows (often one of the first symptoms),
possible involvement of hair in other areas (e.g., armpits, pubic areas),
presence of erythema and perifollicular hyperkeratosis (keratosis around the follicles).

In the histopathological picture, perifollicular fibrosis and atrophy of follicular structures are observed. The disease has a chronic and progressive course, although the rate of progression varies.

Frontal baldness – causes

The etiopathogenesis of frontal alopecia remains complex and multifactorial. Contemporary research indicates the involvement of immunological, hormonal, and environmental mechanisms.

The most important etiological factors include:

1. Autoimmune mechanisms

abnormal immune system response directed against hair follicle structures,
activation of T lymphocytes leading to damage of follicle stem cells.

2. Hormonal factors

androgen-estrogen balance disorders,
particular predisposition in postmenopausal women,
possible hypersensitivity of hair follicles to dihydrotestosterone (DHT).

3. Genetic predispositions

familial occurrence suggesting the involvement of hereditary factors,
polimorphisms of genes associated with the immune response.

4. Environmental and exogenous factors

chronic exposure to UV radiation,
the use of certain cosmetics (hypotheses regarding UV filters and chemicals),
oxidative stress.

5. Inflammatory factors

chronic inflammation of the scalp,
skin microbiome disorders.

It is worth emphasizing that frontal alopecia often coexists with other autoimmune diseases, which further confirms its immunological basis.

Frontal alopecia – symptoms

Symptoms of frontal alopecia develop gradually and may initially go unnoticed. As the disease progresses, the clinical picture becomes increasingly characteristic.

The main symptoms include:

Changes within the hairline:

recession of the frontal hairline,
thinning of hair in the temporal area,
loss of hair density in the anterior part of the scalp.

Skin symptoms:

erythema (skin redness),
sensation of burning, itching, or tension,
presence of scales and perifollicular hyperkeratosis.

Hair loss in other locations:

thinning or complete loss of eyebrows,
loss of eyelashes (less frequent),
reduction of body hair.

Structural skin changes:

smoothing of the skin surface,
absence of visible follicular openings (a feature of scarring alopecia),
progressive fibrosis.

In the course of the disease, an active phase (with dominant inflammation) and a stabilization phase can be distinguished, in which the inflammatory process subsides, but hair loss remains permanent.

Frontal alopecia – treatment

Treatment of frontal alopecia is a significant clinical challenge and requires a multi-directional approach. The primary goal of therapy is above all to inhibit the inflammatory process and slow down the progression of the disease, as the regeneration of lost hair follicles in the case of scarring forms remains limited.

1. Pharmacological treatment

glucocorticosteroids (topical, injectable, or systemic) – reduction of inflammation,
calcineurin inhibitors (e.g., tacrolimus) – modulation of the immune response,
anti-androgen drugs (e.g., finasteride, dutasteride) – impact on hormonal balance,
hydroxychloroquine – immunomodulatory effect,
retinoids – regulation of keratinization processes.

2. Regenerative and supportive therapies

Contemporary management of frontal alopecia includes procedures aimed at improving the microenvironment of hair follicles, supporting repair processes, and modulating inflammation. These therapies are supportive in nature and are used primarily at the stage where active hair follicles are still preserved.

The most commonly used methods include:

scalp mesotherapy – intradermal application of preparations containing, among others, amino acids, vitamins, biomimetic peptides, and trace elements that support cellular metabolism, improve microcirculation, and favor the extension of the anagen phase,
platelet-rich plasma (PRP) – an autologous blood platelet concentrate rich in growth factors (PDGF, TGF-β, VEGF) that stimulate angiogenesis, cell proliferation, and regenerative processes within the hair follicle,
therapies based on progenitor cells and growth factors – aimed at rebuilding the stem cell niche and improving intercellular signaling within the pilosebaceous unit.

3. Physical technologies

Supportive therapy also utilizes physical methods aimed at improving cellular metabolism and blood supply to the hair-bearing skin:

low-level laser therapy (LLLT) – stimulates mitochondrial activity, increases ATP production, and supports regenerative processes,
therapies using electromagnetic waves and high-frequency currents – improve microcirculation, increase tissue oxygenation, and influence the activity of skin cells,
radiofrequency technologies (e.g., INDIBA) – have a biostimulating effect by increasing the metabolic activity of cells, improving tissue perfusion, and supporting repair processes.

The mechanism of action of the above methods includes:

improving skin blood supply,
increasing the availability of oxygen and nutrients,
stimulating the activity of skin cells and hair follicles,
modulating local inflammatory processes.

The effectiveness of supportive therapies remains highest in the initial stages of the disease, when it is still possible to maintain the function of some hair follicles.

4. Supplementary management

elimination of skin irritants,
protection against UV radiation,
individually selected dermocosmetic care,
dietary support (antioxidants, omega-3 fatty acids).

In advanced cases, after stabilizing the disease, the following are considered:

hair transplant (only in the absence of an active inflammatory process),
prosthetic solutions (hair systems).

The effectiveness of treatment depends on early diagnosis and implementation of therapy. The earlier the inflammatory process is inhibited, the greater the chance of preserving existing hair follicles.
