Platelet-rich plasma or PRP is used by multiple medical specialties with demonstrated effectiveness including Dermatology.
Androgenetic alopecia is pathology with important psychological implications for the patient and it is often difficult to obtain a satisfactory clinical improvement.
Beside the minoxidil and finasteride treatments, PRP has shown to provide significant clinical improvement in certain patients.
What does it consist of?
The platelet-rich plasma or PRP technique consists in applying a portion of the platelet-rich plasma of the patient by means of mesotherapy injections. The goal is to promote regeneration or to stimulate the growth.
The process takes 30 minutes and involves the following steps:
- The blood sample is drawn (just like a routine blood test is done).
- Blood centrifugation to separate the PRP fraction from the remaining parts of the blood to be rejected.
- We activate PRP using calcium chloride. This allows the platelets to release their growth factors.
- Infiltration of PRP in the scalp.
Is it safe?
Since the PRP and the growth factors come from the patient’s own body, it is a fairly safe procedure, which avoids the risk of possible allergic reactions.
By obtaining the patient’s blood the resulting growth factors will be specific to the patient’s tissues, thereby is the treatment achieved truly personalized.
According to published reports:
- PRP has shown a hair increase density from the very first 3 months of treatment.
- When applied after hair transplant surgeries, PRP helps to increase the higher densities.
Although PRP seems to be a logical alternative to promote tissue regeneration through growth factors, studies on its effectiveness in the treatment of androgenetic alopecia are still too recent.
On the other hand, we currently do not have standardization systems to obtain the PRP, protocols that establish the appropriate frequency of their application or the minimum amount to be injected to be effective.
However, it is considered that the platelet concentration should be four or five times higher than the normal values to obtain optimal results.
PRP can be considered as a novel technique that can be combined with other treatments to optimize the results.
