Cortisone may help hair regrow by altering the local environment, with regrowth starting 3-4 weeks after treatment, but its use is not widely recommended.
In this conversation, people discussed how Minoxidil and Finasteride can be toxic to cats if ingested. It was highlighted that even when being careful with application, there is still a risk of poisoning due to the potential for contact between fur/hair and the substances.
A user shared a tragic experience where their cat died after being exposed to Minoxidil, warning others of its toxicity to pets. Some users discussed switching to oral hair loss treatments, while others expressed condolences and shared their own concerns and experiences with topical treatments around pets.
User experienced shortness of breath, high blood pressure, red eyes, and eye floaters after using RU58841 for hair loss. They warn others to avoid RU58841 and stick to finasteride, minoxidil, and dutasteride.
Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.
