Hair Injections


Hair injections are a useful tool using a wide range of multiple active agents or medications in order to treat many forms of alopecia.

It is a simple, fast process involving microinjections directly into the scalp of the affected area, using a very small needle containing the chosen medication, following local anaesthetic, be it cream or aerosol.

There are several innovative forms of therapy - such as vitamins with non-reticulated hyaluronic acid, biopeptides, antiandrogens, and corticosteroids - that can aid us in the revitalisation of the hair follicles and scalp by activating the follicular growth cycle and inhibiting hair loss.

Biostimulation by way of injection is suggested in many situations. It is necessary to be supervised and informed by a medical specialist, in order to receive the appropriate advice.

Most frequent forms of alopecia:

Telogen Effluvium:

This is one of the most frequent causes for medical consultation regarding hair, and it´s nothing more than a sudden increase in hair loss. The problem arises because hair in the anagen phase (growth) skips the catagen phase (transition) and goes directly to the telogen phase (detachment), hence the name telogen effluvium, where a large quantity of hair falls out for no apparent reason. Occurring both in men and women, it can arise due to the use of medication, hormonal changes, a post-partum stage, chemotherapy, and sudden emotional changes; in addition to the stress factor, which is not a direct cause but can indirectly influence the acceleration of the process.

Androgenetic Alopecia:

Male hormones are called androgens (testosterone), and they are responsible for hair loss and hair density decreasing as a result of androgenetic alopecia, in both males and females. A form of medication called “antiandrogens” inhibits the activity of these male hormones on hair follicles, reducing the hair loss phase and, as a result, increasing hair density.

They are generally administered orally, but there is now a highly innovative medication that can be applied directly through injections into the scalp. Its name is dutasteride. Applied through microinjections into the scalp, the procedure sees outstanding results - when used a complement - in patients who are already undergoing oral treatment with another antiandrogen such as finasteride; this is in addition, however, to patients under no course of oral treatment, be it due either to limited results or side effects. It is necessary to plan a programme for the injection sessions, which can vary across a period of every four to six weeks, or three or six months.

Alopecia Areata, Frontal Fibrosing Alopecia, or Autoimmune Conditions.

These are autoimmune forms of alopecia where the aetiology is not particularly clear but involves an immunological factor where the body itself attacks the hair follicles directly. One case is alopecia areata, which appears frequently in children - although it is not uncommon in adults - and generally follows stressful situations such as being separated from parents, the loss of a close relative, high levels of stress, etc. In the majority of cases, it is limited to round shapes that can appear in the scalp, eyebrows, and beard.

Another case is frontal fibrosing alopecia, which occurs, in the majority of cases, in female patients, generally menopausal, involving hair loss in the frontoparietal region and eyebrows. Recession and hair loss occur in the frontal hairline, which begins to recede, and in the eyebrows. Patients can develop very thin, shiny-looking skin and redness of the skin in the area surrounding the frontal hairline.

Other cases of autoimmune alopecia can include lupus, lichen planus, and other conditions that affect and attack the hair follicles in different ways. These, however, are less frequent than the leading causes.

For the treatment of these autoimmune conditions, we have at our disposal corticosteroids, which modulate the immune response in order to control the activity impacting upon the hair follicles. In some cases, such as alopecia areata, it is possible to achieve full remission, with the hair follicles recovering and growing. In others, it is possible for the activity to go into remission, whilst preventing the autoimmune activity from progressing, without, however, being able to recover hair density.

Seasonal Hair Loss

The changing seasons can also affect hair density. It is well known that our bodies adapt to the climate, and these changes can affect the density of our hair, leading to an increase in hair loss, especially in spring and autumn. For such cases, we come equipped with several guidelines using vitamins, peptides, and growth factors to revitalise the hair follicles.

However, it is important to point out that hair biostimulation therapies are proactive, and not confined to strict templates. Several, therefore, can be given to the same patient, and they can be carried out in tandem with other autologous therapies such as growth factors, or even be combined with patients who require surgery in the form of microplugs.

These innovative tools are often sought as a preventive measure by patients who simply want to revitalise, prevent loss, and improve the look of their hair.

It is a simple, fast process involving microinjections directly into the scalp of the affected area, following local anaesthetic and using a very small needle containing the chosen medication, before again applying local anaesthetic, be it cream or aerosol.


  • Revitalises the hair follicles and scalp 
  • Increases the thickness and volume of hair 
  • Activates the hair growth cycle 
  • Inhibits hair loss 


There is no specific preparation for this treatment. It is necessary to be supervised and instructed by a medical specialist, in order to receive the appropriate advice.


Normal activities can be resumed following the conclusion of the treatment.


This will depend upon the particular needs of each patient and will consist of a mixture of minerals, coenzymes, vitamins, amino acids, nucleic acids, and peptides, among others.

The needle used is very small and only small volumes of the active substance are injected. As a result, the procedure is practically painless. 

Following the treatment, you will be able to continue with your normal daily life.

Many times the application of medication by microinjections into the scalp should be combined with other therapies such as oral supply or growth factors. This means that there must be a proper indication and supervision by a specialist.
