What is Cetirizine?
Cetirizine is a second-generation antihistamine that blocks histamine H1 receptors.
Beyond allergy symptoms, histamine pathways may influence inflammation and signalling around the hair follicle.
Some research has investigated whether reducing local inflammatory activity may support a healthier follicular environment.
How does topical Cetirizine work?
Potential mechanisms include:
Reducing inflammatory signalling
Inflammatory pathways may contribute to an unfavourable scalp environment in some individuals.
Cetirizine may help reduce local inflammatory activity.
Supporting follicle environment
By influencing inflammatory mediators around the follicle, cetirizine may potentially support follicle function.
Targeting prostaglandin pathways
Some studies have explored the relationship between antihistamines, prostaglandins and hair follicle biology.
