In the simplest of terms, PRP or “Platelet-Rich Plasma” therapy is an innovative hair restoration technique that stimulates new hair growth. By using an extremely fine needle, the doctor injects the patient’s scalp with PRP so the same red blood cells that aid in tissue healing can stimulate hair growth naturally. The procedure has proven to be just as effective for women as it is for men.
Evidence of the therapy’s efficacy was published in a Journal of Cosmetic Dermatology article (EPUB 2017 Mar 13) entitled “Platelet-rich plasma for androgenetic alopecia: Does it work?- Evidence from meta-analysis.” According to the study, the people who underwent PRP therapy experienced a 24% increase in new hair growth (per square cm of scalp) and a 42% increase in the thickness of their hair.
The article discussed the results of 6 separate studies wherein 177 patients used PRP therapy to stimulate their scalps and promote new hair growth. The findings confirmed the results mentioned above. Furthermore, the women who participated in the study experienced the same results. The findings of the study have reflected some extremely positive patient results.
In addition to the stimulation of new hair growth, PRP therapy has also been effective at reversing thinning and restoring fullness. It has also been shown to be well tolerated among the men and women participating in the study. Naturally, some individuals had side effects but none of them were serious enough to warrant serious medical attention. Additionally, the findings of the study support the use of PRP therapy before having a hair transplant procedure performed as well as in conjunction with the surgery.
The most common complaint was that it felt like mild sunburn but that it dissipated almost as quickly as the sensation started. It was also noted that some of the patients experienced pinpoint bleeding during the procedure, the number of which was not felt to be significant. Patients were also admonished against taking any anti-inflammatory medications because they could interfere with the patient’s ability to heal naturally.
The recommended course of PRP therapy is a series of 3 or 4 treatment procedures that are spaced no more than 3 weeks apart. This should be followed up with a single PRP therapy maintenance procedure every 6 months once the initial procedure has been completed. Keep in mind that there must be healthy hair follicles present in order for the procedure to be effective. Otherwise, you will not be deemed a good candidate for PRP therapy. However, it is best to discuss your case with the leading hair transplant specialist and they will be able to evaluate your issues better.
