Like I said, in another study that I do not have access to at the moment there is another pathway activated by capsaicin which accomplishes potentially the same issue that 6-gingerol does.
Also I have inflammatory gut problems and capsaicin has never, and I mean -never- helped with that, it's always been a guilty pleasure that has left my stomach and guts sore afterward.
You were flat out wrong about ginger, so please concede you may be wrong about this.
The study is here:
Ginger (Zingiber officinale) has been traditionally used to check hair loss and stimulate hair growth in East Asia. Several companies produce shampoo containing an extract of ginger claimed to have anti-hair loss and hair growth promotion ...

6-Gingerol (>95% purity; Sigma Chemical Co., St. Louis, MO) was dissolved in dimethylsulfoxide (DMSO; Solarbio Science & Technology Co., Ltd., Beijing, China).
DPCs (3 × 104 cells/well) were seeded into 96-well plates and incubated for 24 h before adding 6-gingerol at 5 or 10 µg/ml and then incubated at 37 °C for 48 h.
An isolated compound of ginger dissolved in DMSO and used in vitro at a really high concentration for 48 hours. I don't think that this shows that I was wrong about ginger, you will probably never reach those concentrations for that long in your body.
In fact, this compound is not even bioavailable as it is in humans, it suffers rapid glucuronidation and sulphatation.
Results
No participant had detectable free 6-, 8-, 10-gingerol or 6-shogaol, but 6-, 8-, 10-gingerol and 6-shogaol glucuronides were detected.
Even then, the concentration peaks at way lower than 1μg/mL.
The Cmax and AUC values (Mean±SE) estimated for the 2.0 g dose are 0.85±0.43, 0.23±0.16, 0.53±0.40, and 0.15±0.12 μg/mL.
And the half-life is way shorter than 48 hours.
The corresponding tmax values are 65.6±44.4, 73.1±29.4, 75.0±27.8, and 65.6±22.6 minutes and the analytes had elimination half-lives < 2hr.
Ginger demonstrates promising anticancer properties. No research has examined the pharmacokinetics of the ginger constituents 6-, 8-, 10-gingerol and 6-shogaol in humans. We conducted a clinical trial with 6-, 8-, 10-gingerol and 6-shogaol examining ...

You made a ludicrous and unsubstantiated claim, and you accusse others of being wrong without even citing any solid evidence. I may be wrong, mind you, this is not my area of expertise, but I don't think that you have any base to: a) make your first assertion. b) tell me that I am wrong, since I did not even proclaim the favorable effects of the use of ginger to the health of the hair.
Research Ginger and inflammation and microbiota if you are interested in learning something beyond "how you are left", until then, you are probably better off "not talking sh*t" in a forum not dedicated to research.
