Clinical trials comparing long-term efficacy of different PRP protocols in a crossover fashion are required in order to determine the gold-standard of treatment in both male and female AGA and improve clinical outcomes. Clinically, FAGA is characterized by diffuse thinning of the crown and vertex region, with the front hairline variably affected. Mild recession of the frontal hairline is rare in pre-menopausal women, being observed in 37% of post-menopausal age [17]. The occipital area is spared, being the significant difference among hair density on the crown and in the occipital area a clue for diagnosis.
Preparation of platelet-rich plasma
When considering platelet rich plasma therapy, choose a surgeon with significant experience performing the procedure. Friends, family members or an internist or primary care doctor are often helpful in suggesting the best surgeon. Rapaport says PRP has been shown to help both men and women, mainly those with androgenetic alopecia, which is known among men as male-pattern baldness and among women for leading to thin hair all over the head, according to the U.S.

This clinical pattern is due to the different characteristics of hair follicles in the different areas of the scalp. One of the main differential diagnoses of FAGA is female pattern hair loss (FPHL), which is a term used to describe the decrease in central scalp hair density that occurs in a number of females after puberty. Although there is not a clear difference between FAGA and FPHL, some authors call female alopecia with androgen increase female FAGA and call female alopecia without androgen increase FPHL [18,19,20]. In this review, we used the general term FAGA to omologate the search strategy. PRP can be used as a new therapeutic option for hair loss including androgenetic alopecia and female pattern hair loss, either as a monotherapy or an adjuvant to conventional therapy or hair transplantation.
Step-by-Step What Happens During PRP Therapy
As to the patient’s perspective, patients’ quality of life and satisfaction were investigated through a 16-item quality-of life (QOL) questionnaire, 7-item questionnaire, patient’s satisfaction scale, and custom surveys. Dermoscopy and videodermoscopy of the hair and scalp (trichoscopy) were introduced in the early 2000s [29,30,31]. In FAGA, hair shaft thickness heterogeneity (anisotrichia) in patterned areas of the scalp is the most prominent trichoscopic feature. Trichoscopy has been proved to be a useful tool in the management of FAGA, especially in monitoring therapeutic response by comparison of seriate images [32]. Ludwig first introduced clinical grading of FAGA, describing three stages of severity ranging from rarefaction of the hair on the crown (I) to near-total baldness (III) [22]. Second, assessing the stage of the disease is necessary in order to choose the most appropriate therapeutic management.

Alopecia causes vary, and for androgenetic alopecia specifically, various risk factors from genetics to age could be the root of your symptoms. You may see it offered as a service at a spa, but Rapaport says to be careful if a thorough consultation isn’t included. He says PRP can be dangerous if technicians are sloppy and aren’t using FDA-approved tubes or aren’t careful about making sure your blood — and only your blood — is injected. Initially used to heal joints, PRP has been gaining traction over the past few years as an innovative way to encourage hair growth.

Likewise, it has been observed that women without circulating androgens may also develop FAGA, further questioning the role of androgen levels in the development of FAGA [25]. This could explain the variable response of FAGA to androgen inhibition therapy [12]. PRP has been shown to help with hair transplant survival by pretreating areas prior to harvesting. There have been studies where PRP has been used in the treatment of vitiligo, melasma, skin rejuvenation (wrinkles, skin atrophy, scar treatment, photo aging), wound care, soft tissue augmentation and enhanced fat grafting.

The number of sessions can vary, but providers typically recommend three to four PRP sessions spaced four to six weeks apart for optimal results. Maintenance treatments every six to 12 months are sometimes necessary for continued regrowth. We prepared PRP by double spin method, in which blood cell layers were manually separated. Activation of platelets through coagulation triggers the secretion of various growth factors, which produce mitogenic effects in various cell types. Activated PRP promotes the proliferation of dermal papillary cells and prevents their apoptosis. FAGA is a slowly progressive disease, with a progression rate estimated to be around 10% per year [41].
As previously suggested, patients’ feelings about hair loss are complex, and perceived efficacy of a given treatment may have a significant impact on their satisfaction and quality of life [60]. The idea of receiving a new, promising treatment such as PRP may positively affect their perception by a placebo-like effect. The autologous nature of PRP may also play a role, being perceived as more “natural” and free of the potential side effects reported for other treatments for FAGA. The relative ease of administration compared to more time-consuming treatments such as topical minoxidil may also result in a greater overall satisfaction.
Androgenetic alopecia (AGA) is a common hair loss disorder caused by genetic and hormonal factors that are characterized by androgen-related progressive thinning of scalp hair in a defined pattern. Currently, U.S. Food and Drug Administration-approved treatments for AGA include oral finasteride and topical minoxidil. Due to the limited number of effective therapies for AGA, platelet-rich plasma (PRP) has become an effective alternative treatment. PRP is an autologous concentration of platelets in plasma with numerous growth factors that contribute to hair regeneration.
This successful track record prompted researchers to study the effects of PRP therapy in the treatment of bald spots and hair loss and thinning in men and women. The answer is, there is much we don’t know about the optimal wavelengths and dosing for PBM therapy to treat hair loss. Despite the studies that have been performed, important questions remain unanswered. For patients, it is advisable that prior to making the decision to purchase an OTC device to treat their hair loss all therapies and options should be reviewed with a hair loss specialist. "Much work needs to be done before a 'one-and-done' hair growth treatment is developed," she says. The authors of an additional review of clinical studies, which the International Journal of Women’s Dermatology published, considered PRP to be a “promising” treatment for hair loss, based on their findings.
We observed significant heterogeneity in assessment methods of hair regrowth, although photography and phototrichograms were the most used. Standardization of quantitative and objective measurements of hair regrowth is needed in order to compare results [57]. The paucity of studies did not allow us to evaluate effectiveness of PRP according to different preparations and techniques.
You’ll get a routine blood draw, and a provider will place the blood in a centrifuge (which concentrates the platelets and the growth factors within the platelets). The PRP will be placed in a small syringe and then injected with a small needle into the areas of hair thinning (if hair loss is being treated). In areas of facial aging, PRP will be spread on your face at the time of microneedling. One of the most popular current uses is in the treatment of hair loss in both men and women. While not all patients with male or female pattern hair loss respond to it, there have seen some very exciting results.
In affected individuals, the hair cycle is altered with a progressively decrease in the anagen phase with each successive cycle, while the telogen phase remains constant. This results in progressive shorter and thinner terminal hair, replaced by short fine vellus hair. In dermatology, we primarily use it for hair loss disorders (androgenetic alopecia). The International Society of Hair Restoration Surgery (ISHRS) is a global non-profit medical association and the leading authority on hair loss treatment and restoration. This treatment involves the collection of your blood in a special tube, which is then spun down using a centrifuge to separate the plasma and platelet portion using the separate gel as a special filter.
