Intralesional platelet rich plasma vs intralesional triamcinolone in the treatment of alopecia areata: a comparative study

Platelet-rich plasma efficacy in alopecia areata patients with normal and elevated levels of antibodies against thyroglobulin and thyroid peroxidase

AIM

To evaluate and compare the efficacy of platelet-rich plasma (PRP) therapy in alopecia areata (AA) patients with normal and with elevated levels of anti-thyroglobulin antibodies and/or anti-thyroid peroxidase antibodies.

Low Level Laser versus Platelet-rich Plasma in Treatment of Alopecia Areata: A Randomized Controlled Intra-patient Comparative Study

Abstract                                                                                                           Background: Non-scarring alopecia areata (AA) is a disease that is mediated through autoimmunity. Recently, autologous platelet-rich plasma (PRP) and photobiomodulation (PBM), commonly known as low-level laser (or light, LLLT) have been suggested to provide a valuable role in stimulating the growth of hair follicles (HF) Aim: Compare between the significance and wellbeing of PRP and LLLT in the management of AA. Patients & methodology: Thirty patients, each having three patches of AA participated in the study. Patches were assigned randomly to have one of the two treatments: PRP or LLLT. The third patch served as a control and received placebo treatment. PRP was done once weekly whereas LLLT was done 3 sessions per week for a maximum of 6 weeks. Patients were followed up at one month and three months. The thickness and density of hair were evaluated by the folliscope. Results: A noteworthy higher improvement was detected in the thickness and the density of hair in the PRP treated patches as evaluated by the folliscope and patients satisfaction. The obtained outcomes were sustained during the 12 week follow-up period in most of patients. Conclusion: PRP and LLLT could be considered as efficacious alternatives for the treatments of  AA with the least morbidity in addition to a little cost profit ratio. KEYWORDS: Alopecia areata, platelet-rich plasma, folliscope, photobiomodulation, low level laser therapy.  

Platelet-Rich Plasma in the Treatment of Alopecia Areata: A Review

Platelet-rich plasma (PRP) is an autologous preparation of plasma with concentrated platelets containing various growth factors and cytokines that enhance the body's inherent capacity to repair and regenerate hair follicles. A few studies and case reports support the use of PRP for the treatment of alopecia areata (AA). Further large-scale studies are needed to evaluate the efficacy of PRP as monotherapy or in association with other therapeutic modalities for AA. Although PRP is relatively safe and potentially effective, there is no standardized protocol or recommendations for the number of PRP sessions required to treat and maintain hair growth.

An Overview of the Biology of Platelet-Rich Plasma and Microneedling as Potential Treatments for Alopecia Areata

Platelet-rich plasma and microneedling have been investigated recently as potential therapeutic options for the treatment of hair disorders. Evidence from laboratory studies indicates that these treatments enhance growth factor production that in turn facilitates hair follicle development and cycling. Several small studies and case reports have presented encouraging findings regarding the use of these treatments for alopecia areata. Future investigations will be needed to validate these therapeutic techniques for patients with alopecia areata and further refine which subtypes of the disease these methods are best indicated for.
