Stopped using this after learning it can be fatal to pets.

There's just too many possibilities of them coming into contact with it to risk it.

It's not, I didn't mean to reply to the other comment. Just sharing an alternative option.

Why would liquid be safer for pets? The problem is Minoxidil for pets, not the foam.

I have cats and I have been using minoxidil for 1 year. My cats are healthy and I never had any issues with them. I try to keep the bottle in the bathroom, inside a drawer, and I always keep the bathroom door closed.

Also, I use the liquid version which is much cheaper and works better for my curly hair. Do not worry about the "For Use By Men Only", 5% is perfectly fine and the adequate amount for both men and women.

Is this effective? Costco also peddles infrared devices for balding. Anytime I see a hair growth treatment, I ask myself if it's effective, then why are billionaires like Bezos bald AF?

I was never able to find the liquid version in club in Southern California. They only carry the more expensive foam version.
