Study summary

This study aims to compare the effectiveness of secretome injection and intradermal platelet-rich plasma (PRP) injection on hair density and the terminal-to-vellus hair ratio in patients with androgenetic alopecia at Prof. Dr. I.G.N.G. Ngoerah General Hospital.

Read the detailed description

This research is an experimental study with a randomized controlled clinical design involving two intervention groups: one receiving secretome injections and the other receiving intradermal platelet-rich plasma injections. Evaluations are conducted by measuring hair density and the terminal-to-vellus hair ratio before and after treatment using trichoscopy/dermoscopy.

What researchers measure

Primary outcomes

  1. Terminal-to-Vellus Hair Ratio

    The ratio of terminal hair (thick, pigmented hair, diameter \>40 micrometer) to vellus hair (fine hair, diameter \<30 micrometer) in areas of androgenetic alopecia

    Time frame: Baseline (before treatment), post-intervention (at 8 weeks), and during follow-up visits (months 3, 6, and 9)

  2. Hair density

    The number of hairs per specific scalp area was measured in hairs/cm²

    Time frame: Baseline (before treatment), post-intervention (at 8 weeks), and during follow-up visits (months 3, 6, and 9)
