Stemoxydine
Stemoxydine is a cosmetic compound from L'Oréal pitched as mimicking the low-oxygen niche of follicle stem cells, with no peer-reviewed trial.
What it is
Stemoxydine is a patented cosmetic active used in L'Oréal Professionnel serums. The sources available are retailer, clinic and forum pages rather than primary literature, and they repeat a manufacturer-run study that could not be verified. It is sold as a cosmetic in the US, EU and UK.
How it works
The proposed mechanism is inhibition of an oxygen-sensing enzyme (prolyl-4-hydroxylase), which would mimic low oxygen around stem cells. This has not been tested in published hair studies of the compound itself.
What the studies show
- A search of the medical literature found no studies of stemoxydine.
How it's used in studies
No use has been published. Products list a 5% concentration.
Side effects and safety
There are no published safety data.
Bottom line
Manufacturer claims only. It is not supported by evidence, so do not pay extra for it. Discuss with a doctor before replacing a proven treatment with it.
