I have actually already been doing pretty much what you guys are planning. A quick summary.
On June 13th I used a 180 sandpaper on the top of my scalp and in front of my hairline. A bit painful even after applying a lidocain cream so be sure to have some pain killers.
I was specially careful to wound deep enough in front of my hairline since no hair is growing there. The area was very red and I stopped at first sign of blod.
For the first eight days I ate an antibiotic (doxi…? dont remember) since I read in the patent that mice who fed on this for nine days grew pigmented hair. But they were geneticly altered so it may not have this effect on humans.
48 hours after the wounding I started applying an immunosuppresant (Elidel cream) once a day for 9 days. I am not sure why immunosuppresant are in the patent but I figured that maybe it suppresed the Wnt signaling and caused pigmentation of the hair. Took a gamble on that one.
My intention was to apply the EGFR inhibitor (Arava, leflunomide) when the crust would fall of but the order came in late. The crust fell of after a week and on the twelfth day I could apply a 0.5 % leflunomide solution (300 mg arava crushed and mixed in 2% minox) twice a day for eight days. I also applied spectral dnc-l (for better absorbtion of the leflunomide) and flutagel. I did not wash my scalp for one week and could not go outside without something on my head so be prepared for that.
There is no sign of new hair growth after three weeks, in the patent they mention seeing new hair as early as 25 days so my experience may have failed. If so it could be that I missed the “window” and should have applied the minox/leflunomid/flutagel much earlier. There was no signs of sideeffects I might add, and the arava was pretty cheap (70 dollars). Other egfr inhibitors might be better though.
I believe there are two crucial points in succesing with this. First the wounding must be deep enough (I stopped when I started seeing blood) and the other is the timing of application. When wounding the mice by cutting they waited 11-12 days and then applied the egfr inhibitor, which was followed by hair growth. When doing abrasion the skin heals quicker so therefor I believe the application should take place 3-5 days after wounding or maybe directly when the crust falls of (day seven). I dont believe chemical peeling is enough for wounding.
If I dont see any growth at all within a month I will do a new experiment on a smaller area and apply the solution much earlier. The leflunomide solution would easily last three treatments when I apply 1 ml twice a day.
So if anyone is doing their own experiment try applying the egfr inhibitor earlier and using something else then Arava. If enough people dare to try this route we will soon find out the optimal strategy for growing hair. But everyone do this on their own risk!
