Moreover, PRP appears to have a potent anti-inflammatory action, as it promotes the release of mediators such as IL-1 receptor antagonist (IL-1ra), soluble TNF receptors (sTNF-R) I, IL-4, IL-10, IL-13, and interferon γ [64]. Through the secretion of growth factors, adhesion molecules, and chemokines contained in platelet’s alpha granules, PRP is able to promote cell differentiation, proliferation, and regeneration. Host dermal collagen and endogenous thrombin are able to activate PRP (“non-activated PRP” or NA-PRP) however, calcium gluconate, calcium chloride, or exogenous thrombin can be added before administration (“activated PRP” or AA-PRP). These techniques have been proved to be equally sensitive as scalp biopsies for hair detection and growth staging, being widely used in clinical studies [35,36].

The growth factors contained within the alpha granules of platelets act on stem cells in the bulge area of the hair follicles and stimulate the development of new follicles along with neovascularization. Although there have been several studies previously reported, a standard practice for PRP preparation and administration as well as a method to evaluate results have not been established. This literature review was conducted to evaluate the effectiveness of PRP for AGA and discuss the various treatment protocols that have been proposed.

Whether PRP effectiveness in the treatment of AGA is influenced by gender is still not elucidated, with conflicting data resulting from studies investigating the effect of PRP in males and/or females. One recent meta-analysis by Gupta et al. suggested milder efficacy in females compared to males, however, this study did not include several reports listed in our review due to insufficient data. Furthermore, many of the analyzed studies were non-randomized, uncontrolled, and had small sample size [72]. Once again, further larger studies reporting males and females as separate populations conducted in a randomized, controlled manner are encouraged to provide stronger evidence on this subject. Additional variability results from the use of different PRP techniques across reports.
What is the average recovery associated with PRP injections for hair loss?
If you have insurance, speak with your provider to see whether they cover it. If you don’t have health insurance, the PRP therapy’s doctor’s office might offer payment plans or reduced fares for self-payers. The patient's blood is collected, centrifuged, and then the Platelet-Rich Plasma (PRP) is injected into the areas new hair growth is desired. There are approximately 54 million men and 32 million women in the US who have some degree of hair loss.
Evidence for platelet-rich plasma is stronger for some types of hair loss than others
A reduction in hair density at months 6 and 12 after the last treatment was reported by Gkini et al. (2014), but hair density remained above baseline (Kim et al., 2011). The most common side effect reported in the reviewed studies was temporary pain at the injection site. Cervelli et al. (2014) selected 10 patients with male androgenetic alopecia who were not on any other medication for the previous 12 months. The evaluation was randomized, blinded, with a placebo half-head group, and evaluated by TrichoScan. After 3 months, a mean increase of 27.7 hairs/cm2 was found in the treated areas compared with a decrease of three hairs/cm2 in the control areas. In addition, terminal hair density improved by 27 ± 15.3 in the treated areas but decreased by 2.1 ± 12.4 in the control area of the scalp (Cervelli et al., 2014).
Platelet-rich plasma: Does the cure for hair loss lie within our blood?
Studies show that the increased concentration of growth factors in platelet-rich plasma may stimulate or speed up the healing process, shortening healing time for injuries, decreasing pain and even encouraging hair growth. Another 2019 systematic review, which featured in Dermatologic Surgery, examined the findings of 19 studies investigating PRP as a treatment for hair loss. According to the authors of the review, most studies reported that PRP treatments led to hair regrowth in those with androgenetic alopecia and alopecia areata.

Mean follow up of patients is also short to draw conclusion regarding the long-term effectiveness of treatment. Thus, further studies are needed with longer follow up and with large sample size. However, this was only a small-scale study, and further controlled research is necessary to fully assess the efficacy of PRP in hair growth. Schiavone et al. (2014) studied 64 patients with AGA, and injected L-PRP and plasmatic proteins in two interventions separated by a 3-month interval. An evaluation was conducted by two evaluators using the Jaeschke scale and with clinical photographs.

In summary, PRP stimulates hair growth by improving follicle vascularization, inhibiting apoptosis and thereby prolonging the anagen phase, and inducing a faster transition from the telogen to the anagen phase in DP cells. After PRP treatment, hair count was found to be significantly increased in 4 studies [55,56,57,58]. An increase was found greater when compared to saline injections in 2 studies administering NA-L-PRP and AA-L-PRP [50,52]. Conversely, one further study reported no difference in hair count after NA-P-PRP compared to placebo [59].
Platelets and hair growth: What’s the connection?
PRP injections are a non-surgical hair loss treatment for hair restoration, hair follicle health, and scalp hair growth. The entire procedure usually takes less than 30 minutes to complete, and little to no downtime is required. Most patients require multiple treatment sessions—typically once a month for three months. Additional treatments once every three to six months are usually needed to maintain results. These follow-up treatments are needed to boost the factors that contribute to hair regrowth. The beneficial effects of PRP therapy for hair regrowth may vary for each person.
Anyone experiencing hair loss is essentially a good candidate for PRP treatments, but those with early hair loss tend to respond best, says Sadick. "PRP is best used for patients with androgenic alopecia, which is a genetically determined type of hair thinning that typically occurs along the top of the head," adds Zeichner. In women, this might look like a widening part with normal hair thickness at the back of the head.
These data align with those resulting from studies on MAGA, confirming the proposed timing of sessions. In a recently published systematic review, Torabi et al. investigated the effect of PRP on FAGA with positive results in terms of hair density, hair diameter, and patients’ satisfaction [70]. However, 4 over 6 included studies were conducted on populations composed by both males and females, with only 2 studies on female-only samples. To our knowledge, this is the first review conducted on populations composed exclusively of female subjects. PRP has been observed to promote remodeling and healing of several tissues, receiving increasing attention by the dermatological community for its potential use in several cutaneous disorders [46]. Since 2012, several studies have been conducted in order to investigate the potential effectiveness of PRP in inducing hair regrowth in a variety of hair diseases [48].
