Medications
Minoxidil: Is a vasodilator, initially designed as an anti-hypertensive, it was found to be stimulatory to hair growth. It has been used for decades by men and women successfully as a hair loss medication which promotes blood flow to hair follicles.
Finasteride & Dutasteride: Are blocking medications which inhibit the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). Initially prescribed for prostate enlargement, they have been found to be the most effective medications available in treating hair loss, albeit at significantly lower dosages. While generally well tolerated at these lower dosages, occasional side effects include sexual such as decreased libido, erectile dysfunction or reduced semen volume. Gynecomastia & depressive symptoms have also been reported. These side effects are reported in a small percentage of users and are typically reversible upon discontinuing the medication.
Spironolactone: Is designed as a diuretic & anti hypertensive and has been prescribed off label due to its anti androgenic effects.
Ketoconazole: Is an anti-fungal medication available in topical form (shampoo) and, less commonly, in oral form that has been reported to have anti-androgenic properties, which can help reduce hair loss by countering the effects of DHT on hair follicles.
