Dutasteride Microinjection Treatment
It is a new treatment for male and female androgenic alopecia that consists of applying locally the drug dutasteride (anti-androgen drug that allows hair to thicken) on the scalp. It can be used in both men and women.
What does the procedure consist of?
The technique of microinjections with dutasteride (also called antiandrogen infiltration or mesotherapy with dutasteride) consists of applying dutasteride directly to the skin of the scalp so that it reaches a higher concentration to the follicular root and in this way the medicine exerts a direct action favoring follicular thickening. The procedure is performed after truncal anesthesia of the scalp, making it a practically painless technique. It takes approximately 30 minutes to complete, and does not require any previous or subsequent care by the patient. It does not leave visible marks and the patient can resume his activities (driving, working …) immediately.
Scientific evidence of the procedure
There are international scientific publications that support the usefulness of this therapy. Pedro Jaén’s working group has been able to demonstrate that a monotherapy regimen with fewer sessions of dutasteride microinjections is effective in patients with androgenic alopecia. The study was published in the international scientific journal International Journal of Trichology. In our experience, (as in the previously discussed working group, treatment with dutasteride microinjections is more effective and requires fewer sessions than platelet-rich plasma – PRP).
Can it be combined with other treatments?
One of the advantages of the dutasteride microinjection procedure is that it can be used as monotherapy (only treatment), to avoid having to take oral medication or apply topical products, or it can be used in combination with other oral and topical therapies to obtain greater effectiveness.
How often is it necessary to do the sessions?
Since the drug dutasteride has a half-life of several weeks, the dutasteride microinjection procedure can be performed every 3-6 months depending on the type of patient and if you are undergoing other treatments. There are usually enough quarterly sessions to improve hair density. In many patients who also receive oral treatment, we perform microinjections of dutasteride to achieve greater benefit.
Does this therapy have adverse effects?
Like any local treatment, microinjections can produce a little discomfort, which is minimized by applying anesthesia before the procedure. It is possible that the following days the treated area is a little sensitive, although it does not usually require the taking of pain relievers. The procedure has a local effect and the systemic absorption is negligible, so it does not produce systemic side effects.
