Evidence Level

Overview

PTD-DBM is a cell-penetrating peptide developed by researchers at Yonsei University in South Korea. The short version: people usually care about it for hair growth, androgenetic alopecia, wnt pathway activation, topical hair peptide, but the strength of the evidence depends heavily on indication and study type.

PTD-DBM is a cell-penetrating peptide developed by researchers at Yonsei University in South Korea. It promotes hair growth by targeting the Wnt/beta-catenin signaling pathway — specifically by inhibiting CXXC5, a negative regulator that normally suppresses hair follicle neogenesis.

The 2017 study published in the Journal of Investigative Dermatology demonstrated that PTD-DBM could stimulate new hair follicle formation (not just maintenance of existing follicles) in mouse models, which is exceptionally rare for any hair loss treatment. Most hair loss treatments slow loss or maintain existing hair — PTD-DBM showed actual new follicle generation.

Research Snapshot

What the evidence says

Preclinical

PTD-DBM currently shows 0 registered trials from ClinicalTrials.gov, 0 PubMed trial publications (0 RCT-tagged), and 4 PubMed references matching the stored source query. Treat PubMed references as literature surface area, not a count of clinical trials.

Known vs uncertain

Known signals

  • 0 registered trials are tracked from ClinicalTrials.gov intervention records.
  • 0 PubMed clinical-trial publications are indexed.
  • 0 PubMed randomized controlled trial publications are indexed.
  • 4 PubMed references are tracked separately from trial counts and can include animal, in-vitro, review, mechanism, or clinical records.

Open questions

  • Evidence strength may vary by indication, route, formulation, and population.
  • Public anecdotes can highlight interest or concern but do not establish clinical efficacy.
  • Regulatory status and compounding access can change independently from the research literature.

Mechanism of Action

PTD-DBM disrupts the interaction between CXXC5 protein and Dishevelled (Dvl), a key mediator in the Wnt signaling cascade.

Key Research Benefits

Stimulates new hair follicle formation (not just maintenance)
Targets Wnt pathway — fundamental hair growth signaling
Topical application — no systemic side effects expected
Published in Journal of Investigative Dermatology (2017)
Complementary mechanism to finasteride/minoxidil
