DHT inhibition
What is DHT inhibition?
DHT inhibition testing investigates whether ingredients reduce dihydrotestosterone formation or its androgen-receptor effects in hair-relevant models. The mechanism tested must be specified because limiting hormone synthesis differs from blocking its cellular action.
Why do you need this service?
DHT-related studies distinguish inhibition of hormone formation from altered responses to existing DHT. The findings support hair-follicle mechanism research without proving prevention of hair loss or a safe finished-product concentration.

DHT inhibition
Dihydrotestosterone (DHT) contributes to androgen-responsive follicular changes in susceptible individuals. This service investigates defined ways of limiting DHT production or signaling, not a single assay that establishes prevention of hair loss.
Formation of DHT
5α-reductase assays measure conversion of testosterone to DHT using a stated enzyme source or cellular system. Direct product measurement and concentration-response analysis can characterize inhibition of synthesis, with relevant isoforms and reference controls documented.
- DHT formation relative to vehicle controls
- IC50 values where supported by the measured response
- Assay interference and sample compatibility checks
Response to existing DHT
Dermal papilla or other suitable androgen-responsive models can assess receptor signaling in the presence of DHT. Receptor binding, reporter activation, and downstream gene expression answer different questions and should not be treated as interchangeable. A binding affinity requires a dedicated binding experiment. Viability and proliferation measurements help identify nonspecific effects. Neither enzyme inhibition nor altered receptor signaling alone establishes clinical efficacy against androgenetic alopecia.
Separate hormone formation and signalling
5α-reductase assays measure conversion of testosterone to DHT in a specified enzyme or cellular system. Concentration-response data and appropriate controls help characterise inhibition. Relevant isoforms and direct product measurement should be documented.
Androgen-responsive cell models can instead investigate signalling in the presence of DHT. Receptor binding, reporter activity and downstream expression are distinct measurements. Include viability and interference checks before attributing a response to selective inhibition.
Results can rank candidates for subsequent follicle, delivery or human studies. Assay potency is not a safety threshold, clinical proof against androgenetic alopecia or automatic support for hair-growth advertising. Product classification and claim requirements depend on the intended market.
