Hair/baldness

Shampoos add caffeine to overcome genetic male pattern baldness. There is a research article that finds out it helps. Kindly add. — Preceding unsigned comment added by 2003:E9:3F1A:420:BC79:54A9:6F6F:FC99 (talk) 08:11, 16 July 2020 (UTC)[reply]

There are adverts on TV for shampoos and hair treatements with caffeine, but no explanations for why. There doesn't seem to be anything on this page about hair, shampoo or scalp treatment. Does anyone have any sources?

Natural Occurences: unsupported claim

Hello,

I was interested in temperate climate plants that contain caffeine, and this article states in it's Section "Natural occurence":

"Temperate climates around the world have produced unrelated caffeine-containing plants."

However, no listing of such plants or a citation showing one. Other citations provided in the same section may list different plants containing caffeine, but none of them are from temperate areas but rather sub-tropical zones at best. I think since this is the "Natural Occurence" section, it should provide this information more in detail or be removed or changed if it can't be verified or proven.

Cheers

Link to data page

@DePiep: The link to the data page was removed in this edit with the justification not needed, the data page is fully redundant. It is only redundant if the result of the AFD is to delete. If the result is to keep, then Caffeine#Chemical_data section will be deleted, and the data page will no longer be redundant. Please leave the data page link in place while the AFD discussion is proceeding so editors can compare the two solutions side by side. Boghog (talk) 17:31, 14 January 2022 (UTC)[reply]

Nope. The data is redundant. No harm is done when this links is not present, the article is OK. Obviously, you are editing an article to make a point in an AfD ie, off-mainspace. Quite a bad base for a mainspace edit. Anyway, you are editwarring. -DePiep (talk) 17:36, 14 January 2022 (UTC)[reply]

I strongly disagree. We are having a AFD and you delete the data page is under discussion before that discussion has completed which is completely unacceptable. You have also deleted a link to that data page. It is essential that link remain in place for the AFD discussion. How can we possibly have a discussion about material that you have deleted?

Semi-protected edit request on 21 January 2022

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

Please revert this edit. It introduced a typo ("promiment") and removed the connection the previous sentence ("several known mechanisms") had to the rest of the paragraph, making the paragraph no longer make as much sense. 130.208.182.103 (talk) 21:52, 21 January 2022 (UTC)[reply]

Done. It also didn't even form a complete sentence itself. DMacks (talk) 22:47, 21 January 2022 (UTC)[reply]

Is Caffeine regulated in any parts of the world

3rd sentence:

"Unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world."

Is there a source? Why "nearly"? Only because the author was not 100% sure. I vote to delete this sentence.

Alternatively we add the countries that regulate caffeine but again, I couldn´t find any.

178.13.24.90 (talk) 09:07, 26 January 2022 (UTC)bb[reply]

An unclear sentence?

In section "Chemistry", there is the following sentence: "The pyrimidinedione in turn contains two amide functional groups that exist predominantly in a zwitterionic resonance the location from which the nitrogen atoms are double bonded to their adjacent amide carbons atoms". In my opinion, it is not clear. Perhaps, it should be rewritten.Ekisbares (talk) 18:29, 1 February 2022 (UTC)[reply]

ICDM should be ICD

ICDM is mentioned three times: twice as ICDM-9 and once as ICDM 9. The first mention of ICDM links to [[1]], which has no ctrl-f instances of ICDM. A quick google search also redirects to ICD. Would like a second opinion on if this should be ICD in all cases. rex (talk) 16:32, 22 February 2022 (UTC)[reply]

“Darker roasts have more caffeine”

A quick search shows otherwise: A dark-roasted bean contains more caffeine than a light-roasted bean due to its stronger flavor. Not true. – Et0zl Talk☻ 13:53, 30 May 2022 (UTC)[reply]

Mis-spellings in the text. "Judgement" should be "Judgment". Peterdkukla (talk) 10:02, 8 July 2022 (UTC)[reply]

Narcolepsy treatment

This revert was justified because the source did not evaluate caffeine effects on narcolepsy specifically, but rather only included it in the discussion. The one source used here is primary research, too preliminary to justify including it in the article. Best to wait for a WP:MEDRS review on possible use of caffeine for treating narcolepsy, which a PubMed search shows is not available as of 2015, here. Zefr (talk) 14:05, 21 July 2022 (UTC)[reply]

Hi all, so I am trying to add the following sentence : "Caffeine has shown tentative evidence for narcolepsy" in the "Research" category of the article providing the following secondary and reliable reference: https://doi.org/10.2147%2Ftcrm.s244714 . User Zefr does not agree citing https://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable_sources_(medicine) and the fact the evidence is weak and that a wikipedia article is not a news article. I would like to add that we can usually find the same type of claims being made in high ranked wikipedia bio-medical articles (cf https://en.wikipedia.org/w/index.php?search=tentative+evidence&title=Special%3ASearch&go=Go&ns0=1) What are your toughts on this disagreement ? Thanks to you all! Medhekp (talk) 14:07, 21 July 2022 (UTC)[reply]

I agree with Zefr; this research, based on a pilot study with only sixteen participants, is not suitable for use in Wikipedia. That other such stuff may be included in other articles is not a relevant argument. Richard Keatinge (talk) 09:45, 25 July 2022 (UTC)[reply]

Contradiction (of sorts): Under Adverse Effects - Psychological and Adverse Effects - Risk of Other Diseases

In the Adverse Effects - Psychological section, the quote is "Increased consumption of coffee and caffeine is associated with a decreased risk of depression" In the Adverse Effects - Risk of Other Diseases section, the quote is "Caffeine consumption may be associated with reduced risk of depression, although conflicting results have been reported." Both quotes cite references 99 and 100. I myself have not looked into the sources. These two sentences are contradictory. Migy007 (talk) 15:51, 25 July 2022 (UTC)[reply]
