Amini F et al., Life, 2025

Better than controlStrength of design, level 3 of 5: Controlled trialContains plant extracts

Better than control: The treated group did better than the comparison group on the main measures.

Level 3 of 5: Treated patients were compared with a control: placebo, another treatment, or the untreated side of the face. Most exosome trials at this level are small and short.

Design
Randomized, double-blind, saline placebo
People
24 randomized, 20 analyzed
Made from
Not stated in the paper
How it was given
Injected into the scalp, 4 sessions 15 days apart

What they found

At 16 weeks, hair count rose a median of 9.5 hairs in the treated group and 1.5 with placebo. Two treated men had mild scalp irritation that resolved on its own.

What limits it

Small pilot with 4 dropouts. The formulation mixed exosomes (source not stated) with Ecklonia cava and Thuja orientalis extracts, so the effect cannot be pinned on exosomes. The trial was registered on ClinicalTrials.gov only after it was completed. Formulation made by DASAN C&Tech; materials supplied by Cosmedician AP.

    After 12 weeks, hair thickness and count increased more in the exosome group than with minoxidil. Final average hair diameter was 88.8 µm versus 74.2 µm.
