Comparing Platelet-Rich Plasma (PRP) Centrifugation Methods on Thrombocyte Concentration and Clinical Improvement of Androgenetic Alopecia

Study Overview
=================
Brief Summary
-----------------
This research is a preliminary, randomized, double blind clinical trial, which will examine the differences in PRP preparation methods, a single-spin centrifugation of 3000 rpm in 15 minutes compared to a double-spin centrifugation of 1500 rpm in 6 minutes followed by 2500 rpm in 15 minutes, on the results of Thrombocyte Concentration and Clinical Improvement of Androgenetic Alopecia.

Detailed Description
-----------------
Several examinations will be performed in every visit, including history taking, physical examination, trichoscopy and trichoscan. Laboratory evaluations (complete blood count) for the measurement of the thrombocyte for baseline and PRP will be performed for all assented subjects on the first visit. Each subject will be instructed to apply 5% topical minoxidil twice a day everyday as primary therapy during the study

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Single Spin Group<br>Currently, the standard operating procedures for PRP preparation in dr. Cipto Mangunkusumo National General Hospital is by performing a single-spin centrifugation at 3000 rpm for 15 minutes. This first group will received PRP treatment by single-spin centrifugation at 3000 rpm in 15 minutes in addition to topical minoxidil (5%) | Procedure: Platelet-Rich Plasma Injections (PRP) on the Scalp<br>* each subject will be treated with 3x PRP injections on the scalp with 2 weeks interval in addition to daily minoxidil administration.<br>* Other names: Regrou Forte (5% Minoxidil solution);|
| Active Comparator: Double Spin Group<br>This group will received double-spin centrifugation PRP treatment at 1500 rpm in 6 minutes and continued at 2500 rpm in 15 minutes in addition to topical minoxidil (5%) | Procedure: Platelet-Rich Plasma Injections (PRP) on the Scalp<br>* each subject will be treated with 3x PRP injections on the scalp with 2 weeks interval in addition to daily minoxidil administration.<br>* Other names: Regrou Forte (5% Minoxidil solution);|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Thrombocyte Count in PRP and Whole Blood | We assessed the increase in PRP platelet levels by assessing baseline platelets (using whole blood) and assessing platelet levels in PRP preparations and then calculating multiples. platelet valuie units to be used is (/μL) | 6 weeks | 
| Clinical Improvement of Androgenetic Alopecia | We assessed the assessment of clinical improvement in androgenetic alopecia using trichoscopy and trichoscan examination on week 0, 2, 4, and 6. On trichoscopic examination we assessed hair color, hair diameter diversity, vellus hair, and dots. Whereas on trichoscan examination we assessed hair count, hair diameter (mm), hair density (/cm2), hair rate (%) in vellus hair, terminal, anagen and telogen phases and assessed hair mean thickness (mm/cm2) and mean length (mm) and average hair per unit. | 6 weeks |
