Honestly, I used it only for a day- twice. Tried it on a weekend, like Saturday morning, and rode out the pain. This was the nondiluted folligen. I just wanted to scratch my head all the time. Then I tried the same that night, and could NOT get to sleep. Don't mean to sound like a wuss, but seriously, I had to shower and wash my fn hair at like 3am that night, and it still stung after!!! =) Then I tried the 50% diluted with water and it helped, of course, but still itched a bit, and same thing at night, just could not get to sleep. I will try it again this weekend, if you and others swear by it. I think the nizoral, h&s and tgel put my scalp in better shape to some degree, so maybe that will help.
But I love the feel of tricomin, so I can imagine what it must be like to be able to tolerate folligen. And folligen is so damn cheap in comparison.
However, I also heard on some thread on another site of this girl preaching against it. Her story was- tried it, it stung too bad, diluted it, and tolerated it, kept using the diluted for 6 months, and that's when her hair came out "in buckets". So that's why I am a little wary to try it again. I figure, if my head is sensitive to it, don't use it.
Saw your pics on a thread after doing a search on "update". I'm diffuse thinner like you, but admittedly not as far. But you're a dj, you must get all the tang!!! Every guy knows it's the djs and the bartenders you can't compete with. I'm a freegin engineer, 90% of my colleagues are all old dudes, the rest ugly ladies. =)
Good luck, man.
