Different platelet-rich plasma preparation protocols in Female pattern hair loss: Does it affect the outcome? A pilot study.

BACKGROUND

Platelet-rich plasma (PRP) injection is a promising modality for hair regeneration in female pattern hair loss (FPHL). A standard protocol on best methods for PRP preparation has not been established.

OBJECTIVES

To optimize standard PRP preparation protocols and evaluate its clinical efficacy in FPHL.

METHODS

Comparative study enrolled 40 female patients with FPHL divided randomly into 4 equal groups. Each group received 3 sessions of monthly intradermal injection of PRP prepared by different methods regarding number of spins, centrifugation speeds, type of the centrifuge, and the size of PRP tube. Patients were evaluated by trichoscan before and 1 month after the 3rd session for number of terminal, vellus hair, and average hair width.

RESULTS

A statistically significant increase in platelet count in PRP prepared by combination of digital centrifuge, large-sized sodium citrate tube, and low centrifugation speed (900 rpm). All patients showed statistically significant increase in percentage of terminal hair and average width of hair after treatment as assessed by trichoscan, without statistically significant difference between studied groups.

CONCLUSIONS

Digital centrifuge, large-sized sodium citrate tubes, and a single spin with low centrifugation speed (900 rpm) were ideal for PRP preparation. PRP is an effective and safe modality in FPHL therapy.
