During the treatment, a technician draws your blood and spins it in a centrifuge to separate out the platelets and plasma. Doctors then inject the plasma, which helps repair blood vessels, promote cell growth and wound healing, and stimulate collagen production. In a 2014 study of 20 people, PRP treatment increased hair density and peaked at 3 months. The platelet-rich plasma is drawn up into a syringe and then injected into areas of the scalp that need increased hair growth.
Platelet Rich Plasma and Its Use in Hair Regrowth: A Review
Clinical assessment and thoughtful evaluation of FAGA are important for several reasons. After years of cocktailing hair growth supplements and bald spot concealers, a patient decided it was time to try a professional hair restoration treatment. Most candidates note one to two days of recovery following a PRP injections for hair loss treatment. Minimal swelling, flaking, redness and sensitivity resolve within 48 hours. Patients are encouraged to not exercise for one week and limit sun exposure.
1. FAGA: Clinical Features, Pathogenesis and Current Therapeutic Options
Most studies have concentrated on using PRP injections to possibly help the growth of the native hair (and possibly the grafts if surgery was done) in the areas of hair loss and thinning. What these studies have shown so far is that the treatments do not help hair to re-grow on a completely bald head, so the earlier a treatment is started the better. Platelet rich plasm (PRP) is produced by taking the your own blood and placing it in a centrifuge to concentrate the platelets. This concentration of platelets (or “PRP”) is then injected into the area to be treated.
Platelets and hair growth: What’s the connection?
As to hair diameter, it was found significantly increased in 4 studies [55,56,57,58]. In particular, improvement in hair diameter achieved after combination treatment of NA-L-PRP +PRDN was more pronounced than improvement in hair count [55]. Possible side effects following a PRP injections for hair loss procedure include minimal pain, pinpoint bleeding, rendess, full, tight sensations in the scalp, and headache. PRP has a well-documented history of success in the fields of reconstructive surgery, orthopedics, dentistry, oral surgery, and facial rejuvenation.
It works by drawing blood, processing it, then injecting it into the affected area. People with autoimmune conditions are not good candidates for PRP therapy, as the injections may trigger an overactive immune response that can lead to swollen lymph nodes, fever, or joint pain. PRP therapy should only be performed by a board-certified dermatologist or plastic surgeon with the training and expertise to perform the procedure safely. Most people can resume their normal activities almost immediately after having a PRP injection.

Combination treatment of PRP+ polydeoxirybonucleotide (PRDR) injections resulted in a greater increase in hair count compared to PRDN injections only. On the other hand, improvement in hair count after u-PRP was found to be milder than the one achieved after treatment with topical minoxidil [60]. Hair loss and thinning affect men and women alike, often negatively impacting their confidence and self-esteem. Although treatments to regrow lost hair are available, many are invasive or problematic in other ways. Prescription medications for hair loss and thinning can cause unpleasant side effects, while a hair transplant is a costly surgical procedure that has a lengthy recovery time.
DHT showed also to inhibit hair growth through blocking the action of growth factors such as insulin-like growth factor 1 (IGF-1) in mouse models. Furthermore, reduced blood flow and oxygen pressure have been observed in AGA, leaving the hair follicle devoid of nutrients [62]. For this reason, a person would need to receive multiple PRP treatments over time to maintain hair growth results.
Angiogenesis and increased vascularization of the follicle are thought to be critical for the initiation of the anagen phase (Mecklenburg et al., 2000). Conversely, reduced blood flow and oxygen pressure have been observed in AGA (Goldman et al., 1996). The growth factors in PRP act on stem cells found in the bulge area of follicles, resulting in neovascularization and folliculogenesis (Li et al., 2012a, Li et al., 2012b, Takikawa et al., 2011). Increased β-catenin expression, which is believed to increase DP cell proliferation, survival, and angiogenesis was also observed (Li et al., 2012b).
During a PRP session, a technician draws blood, usually from a patient’s arm. Plasma is a substance found in the blood that contains platelets, which promote hair growth, according to the Cleveland Clinic. The technician injects the plasma into areas on the scalp affected by hair loss — usually about 15 to 20 injections per PRP session, Khetarpal says.
Platelet-rich plasma (PRP) is the platelet and leukocyte-containing plasmatic fraction of anticoagulated autologous blood. While evidence supporting the clinical use of PRP in dentistry is low, PRP is widely used in sports medicine, orthopedics, and dermatology. Its beneficial activity is commonly attributed to the growth factors released from platelets accumulating in PRP; however, evidence is indirect and not comprehensive. There is thus a demand to revisit PRP with respect to basic and translational science.
Men and women with androgenic alopecia, a genetic condition that’s characterized by a receding hairline and the gradual disappearance of hair along the front of the scalp and top of the head, also respond well to this treatment. Though PRP to treat hair loss is relatively new, research has been promising. A small study published in the April–June 2014 issue of the Journal of Cutaneous and Aesthetic Surgery tested PRP on 11 men with androgenetic alopecia who had not had success after six months of medication. After three months, they received four treatments and saw their hair count increase by about 30 percent. Doctors began using PRP in dermatology after researchers found that high concentrations of platelets in plasma cells help promote hair growth by prolonging the growing phase of the hair cycle.
