What is PRP + stem cells?
PRP (or Platelet Rich Plasma) uses growth factors present in the blood to stimulate hair regrowth. The cells (platelets) injected release numerous growth factors which act directly on the hair follicles, encouraging them to strengthen existing hair and build new ones. New blood vessels also develop, improving irrigation of the treated area. In this way, PRP slows hair loss and encourages regrowth to increase hair density.
Stem cells, on the other hand, are harvested from your own fatty tissue. When injected into the scalp, they can reverse the shrinkage of hair follicles. What makes stem cells unique is their ability to repair and heal faster. Since stem cells have specific regenerative properties, their ability to treat a variety of conditions and injuries is vast and promising. Recent research has shown that stem cells can now be injected into hair follicles to promote new hair growth.
This treatment is suitable for both men and women, regardless of age, and can be carried out all year round.
What are the indications?
Injections of PRP and stem cells into the scalp canslow hair loss (seasonal changes, hormonal modifications, alopecia, etc.) and stimulate regrowth by treating, for example, incipient baldness: hairline, temporal gulfs, baldness or diffuse alopecia. Certain scalp conditions can also be treated, such as scalp irritation, scalp malnutrition or dandruff.
These injections are most effective for people in the early stages of hair loss, or for patients who are not candidates for a conventional transplant. The treatment is also ideal forwomen who prefer to avoid a transplant or who do not have enough quality hair to perform one.
PRP and stem cell injections can be accompanied by light therapy (LED) and scalp microneedling to optimize hair growth. This treatment is also an excellent complement to hair transplantation, to help grafts take well and accelerate healing in the donor area.
