TLDR Topical cetirizine improves hair density and thickness in androgenetic alopecia, but more research is needed.
A preliminary study with 20 participants found that topical cetirizine increased hair density and thickness in those with androgenetic alopecia after 6 months of treatment. The study suggests that cetirizine may inhibit the production of prostaglandin D2, which is associated with hair loss. However, further studies with larger sample sizes are needed to confirm these findings. Cetirizine has fewer potential side effects compared to other drugs used for androgenetic alopecia, such as minoxidil, which could lead to better patient compliance with the treatment.View this study on tandfonline.com →

No genetic link between prostaglandins and hair loss found.
PGD2 stops hair growth and is higher in bald men with AGA.
Latanoprost, a glaucoma treatment, was found ineffective in treating hair loss in eyebrows and eyelashes.
Plant extracts effectively reduce hair loss and increase growth, offering a safe alternative treatment.
Finasteride works better than Permixon in reducing dihydrotestosterone levels.
