The conversation discusses the potential benefits of castor oil for hair thickening, with one user noting it may increase prostaglandin E2 and decrease PGD2. The original poster plans to take 1-2ml orally daily.
The conversation discusses the potential of topical cetirizine (Zyrtec) for hair growth in comparison to minoxidil, noting cetirizine's ability to reduce prostaglandin D2, which inhibits hair growth. Users share mixed experiences with cetirizine for allergies and scalp health, and there's a mention of the risk of dementia with long-term antihistamine use.
BionicBell discussed using Bimatoprost, a medication typically for eyelash growth, for hair loss and mentioned a compounding pharmacy that can mix it with other ingredients like minoxidil and finasteride.
