You have to try some things to figure out what "stack" works best for you, but the core ingredients are:
- An aggressive maintenance treatment. Something that stops the inflammatory cascade. Lots of options, none good. Side effects usually the big roadblock
- finasteride/dutasteride
- RU or other topical antiandrogens, including Equol (see here)
- Seti/Fevi (see here)
- Zinc+B6 aka Zix - Probably not aggressive enough, but lots of people say it's helping
- Antihistamine - Cetirizine was shown to help in studies, but not a lot of positive results on the forums. Could be that it isn't stable in any vehicle. Desloratidine is promising because it's more stable and in the same class as Cetirizine, but not a lot of info available
- Estrogens - This is really extreme for maintenance, but this guy has achieved it + regrowth
- A way to stimulate regrowth. The more of these you do, the better:
- Wounding - Almost nobody gets regrowth without wounding. You want microneedling, NOT dermarolling. Those rollers shred your scalp extra hard for no benefit, but give you greater risk of infections and scarring. Spread the word, people.
- Typical regimen seems to be 1.5mm every week or two, but it's been said that going deeper is much more effective. My experience with 2.0mm seems to back this up.
- Minoxidil - Almost always part of a wounding regimen. If you apply too soon after wounding, a lot more drug goes systemic - people have reported bags under the eyes and wrinkles on the face. No conclusive evidence, but the science says it's possible. Better to wait 24hrs+
- WNT agonist - Common one is Lithium Chloride (LiCl) 10mg LiCl/1mg water applied while the wound is fresh. Nobody seems to have a solid answer as to the safety or effectiveness of these. Some speculation that this can cause cancer.
- Topical PGE2 - Applied to light wounds (some info here). Supposedly has a massive growth stimulation effect.
- Estrogens - Small amounts used topically can help regrowth (see here)
Regarding other stuff mentioned:
Ketoconazole / Nizoral - Part of the "big 3" but I've noticed exactly zero results from this
PTD-DBM - Too new, still being trialed
DMN-VPA - Is just VPA in the form of dissolvable needles that are injected. PTD-DBM and VPA are being trialed on the forums
WAY-316606 - Related to Cyclosporine A, which we know works, but has
nasty side effects. Pretty new, doesn't seem like anyone's trialing it yet
Thymulin - Supposedly bodybuilders have grown hair when injecting the stuff, but a commercialized topical just hit the market a few days ago. No solid results yet
