I have regrown an inch of full hair on the front of my hairline in about 3 months. That is still 1/2 an inch from my original hairline. I know because at age 11 I walked into a dumpster and had to get stitches right there. The hair line is clean though. Looks cool. Totally unfugly to part. Two months or so of dutasteride but I also use other methods (glycerin and rogaine diluted 1:10 in "distilled water" applied generously, and 500mg of L-cysteine w/ food). I would think spironolactone is helping too but I haven't taken it as long.
QuoteThere is some argument over whether or not Natural Progesterone (also discussed below) is
more efficient tha Finasteride at blocking 5-alpha-reductase activity.
In my opinion it is not. I used Natural Progesterone alone for some time and it did not regrow hair or prevent hair loss. It did seem to make my scalp, um, "swell", like there was an extra layer of fat. My current formulation (topical) has grapefruit extract in it which is said to prevent hair growth, so I can't be sure. I also tried adding a dab of Renova; nothing fell out.
