Re: Bryan, guess what Jayman asked me? (please comment)
This *someone* accused me of believing in Armando's stuff.
I want to state a disclaimer though: I do not believe that it could possibly inhibit sebum production by 100%. Nothing can be that strong. Even if you got rid of all androgens, which castration does not come close to, and dumped lots of estrogen in there, wouldn't you still produce some sebum?
Also, though the link I PM'ed to Bryan says 100% for a full week, I can't help but suspect what they meant was that after a week of application it got down to 100%.
But this is not the point of this thread. The point here is to educate people about why it is so important to see if a product even inhibits sebum production, before using it. Head and Shoulder's zink shampoo increases sebum production, which is why I will never use that stuff again. I grew up using it.

Sorry but which shampoo claims this? I haven't frequented the forums as much as of late.
Thanks.

OK guys, it was rude of me to publicly attack someone. For that I apologize. This someone also said that zinc pyrithione is good for hair.
"Forty-four ketoconazole users and forty-three zinc pyrithione users completed the 6 month study period. Analysis of the different parameters shows that the hair diameter gradually increases with chronic ketoconazole use (+8.46%) over a 6 month period, whereas the diameter shows a trend to decrease with zinc pyrithione use over the same period (-2.28%). The sebum excretion rate is reduced with ketoconazole (-6.54%) while it increases with zinc pyrithione (+8.2%) over the same period of time. The number of hair shed over a 24-hour period is reduced by 16.46% with ketoconazole and 6.02% with zinc pyrithione after 6 months. Finally, the percentage hairs in anagen phase increased by 6.4% and 8.4% respectively during the study time. Except for the percentage of hairs in anagen, which showed no difference between the two groups, all other parameters were significantly different in favor of the ketoconazole shampoo."
There is nothing wrong with sebum production. But sebum production is regulated by hormones. If a shampoo increases sebum production, that means it increased the androgenic activity. If it decreases sebum production, that means it decreased the androgenic activity. Hampster flank organ is the gold standard for invivo experiments, except with 5ar2 inhibitors.
So while sebum is not bad, any ingredient that increases sebum production is bad. Well, unless it is a strong stimulant and only slightly increases sebum production.

A shampoo with 10% licorice extract. Appearantly the same chemical that makes it sweet is a big player in the anti-androgenic properties of licorice. Some of the many studies are posted in the Research section and the experimental section.

A shampoo with 10% licorice extract. I suggest you save money and make your own, though there are links to many such pre-made shampoos.

FYI, ionic zinc and copper are NOT good for skin. They are caustic chemicals. They are also caustic to fungus, just like Listerine is caustic to mouth bacteria. Do not confuse these chemicals with copper and zinc peptides. And only a few of the many possible peptides were found to be beneficial.
Ketoconazole is non-toxic. So is piroctone olamine. These are second generation fungal treatments, and good for your scalp. Head & Shoulders will speed up your balding.

yes, okay?
I asked you why you thought SEBUM was so bad, and I then brought up Armando's theory regarding sebum.
It sounded to me like you were saying that sebum is bad for hair. I disagree. But I guess that is not what you were saying.
I think it's pretty unfair though to take my statemen asking you why sebum is bad for hair, and use that to argue that I told you that increased sebum production is bad for hair. I never claimed anything different.
Sebum is the natural conditioner for hair and very important in my opinion.

The pH of Prox-N is 2.2, according to my lab's pH paper, which is in 0.1 pH increments.
I don't know if there is a dose of zinc sulphate that is good. I just know that certain levels can burn your scalp by acidifying the solution. Prox-N never burned my scalp though.
Good luck spreading 8 drops around your scalp, as directed.
