While advertised as a hair regrowth solution, Minoxidil’s primary result is the overall appearance of hair thickening rather than new growth. It merely ‘fertilizes’ the scalp and may help maintain the hairs already on it, as long as you keep using it.
• Irritation and redness of the scalp
• Rapid heart rate, dizziness, fainting, swollen hands and feet
Finasteride can potentially halt hair loss by blocking DHT in men. This being said, just like Minoxidil, Finasteride is not technically a hair regrowth agent (especially so for women). Sexual side effects can be devastating to men.
