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.

Switching from topical to oral minoxidil, specifically using split dosing, led to significant hair regrowth and reduced side effects for the user. The combination of oral minoxidil and finasteride proved more effective than previous topical treatments.

The new Kirkland Minoxidil appears different, being more oily and lacking crystallization, leading to confusion about its authenticity. Users suggest ordering directly from Costco to ensure getting the genuine product.

The user applies 2ml of a lotion containing 5% minoxidil, 0.3% finasteride, hydrocortisone butyrate, and cetirizine before bed, but it leaves a residue on the scalp. Another user suggests reducing the amount to 1ml, as 2ml results in a high finasteride dosage.

Oral minoxidil may cause heart palpitations, especially in those sensitive to caffeine. It's advised to consult a doctor and consider starting at a low dose or using topical minoxidil.

Switching from topical to oral minoxidil can cause initial hair shedding but may lead to thicker hair growth. Many users combine it with finasteride, experiencing varying side effects.
