Radioimmunoassay of Minoxidil in Human Serum

Higher doses of dutasteride reduce scalp DHT more effectively than finasteride, but have diminishing returns after 3mg daily and may cause more side effects. Combining dutasteride with topical minoxidil can enhance results, but using both finasteride and dutasteride together is unnecessary.

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

Foam minoxidil may be a good alternative for those who experience irritation from liquid minoxidil, though opinions on its effectiveness vary. Some users suggest oral minoxidil as a more effective option with fewer side effects at low doses, while others recommend foam or alcohol-free topical versions for sensitive scalps.

Stopping minoxidil 6 months before a hair transplant may reveal true hair density but could cause shedding. If quitting minoxidil post-transplant, expect potential thinning of minoxidil-dependent hairs; consult a surgeon for advice.

Minoxidil is on sale at Costco, but it poses a significant risk to pets, especially cats. Users discuss the pros and cons of foam versus liquid minoxidil, with some preferring liquid for better results despite its greasiness and dandruff issues.

Minoxidil is highly toxic to cats and can cause fatal heart issues. Users recommend switching to oral minoxidil to protect pets.
