As articles about other animals refer to hair follicles, some effort should be made to discuss these systems in other animals (mammals, insects, etc.) if they are different there. Vivacissamamente 13:58, 6 September 2005 (UTC)

Can we get photos of real hairs and diagrams of the different stages, like [1]? — Omegatron 04:07, 9 November 2006 (UTC)

What is club hair? 82.139.85.220 (talk) 12:07, 5 April 2008 (UTC)

Mention Follicular bundles? Had a scalp treatment yesterday, they used a camera to look at my scalp and I was surprised to see 1, 2 or three hairs from each pore. I've look for some time for information of this and found only one reference to it. It seems it is common while all pictures show one hair emerging and no other site mention this.

DNA testing of hair

CSI (forget which particular series) suggests that only a specific part of the hair (guessing sheath near root) contains testable genetic material. Is there any factual basis? — Nahum Reduta [talk|contribs] 09:09, 31 October 2008 (UTC)

No. Until a year or two ago, current technology only allowed DNA to be harvested from the sheath near the root. That doesn't mean that there isn't DNA in the hair strand itself, just that that particular technology couldn't harvest it from the strand. New breakthroughs allow DNA to be harvested from hair strands. CSI is a really, really bad place to get your science from. --NellieBly (talk) 01:21, 16 March 2009 (UTC)

Wonderful reference article to add

• First, there is a wonderful NEJM article that I referenced a few times in this article, and I think if someone has more time, more content could be cited from it. The article is: Paus, Ralf; Cotsarelis, George. "The Biology of Hair Follicles." The New England Journal of Medicine. 1999; 341(7): 491-497. PMID 10441606. I can email it to you if you contact me.

• Second, if you are interested in the skin, adnexa, or dermatology, I would love some help over at WP:DERM... just fyi. kilbad (talk) 05:19, 11 November 2008 (UTC)

Hi! Thank you for all your hardwork on creating a Wiki-page on the hair follicle! I'm a 4th year Medical Student interested in Dermatology and feel I can contribute positively to improving the information presented on this topic. Please see my workplan below and I'm open to any suggestions to my edits!

Work plan

Hi! I'm a 4th year Medical student at UCSF interested in Dermatology and I have chosen to edit this page as part of the Wikiproject Medicine elective at UCSF. This is a C-class quality article of High Importance in Dermatology. My workplan is as follows: Between 11/27/17-12/15/17 I will improve the lead section, add discussion of differences in hair follicle and appearance of hair, add section on diseases of the hair follicle, add section on treatment of diseases of the hair follicle.Oni1981 (talk) 18:47, 26 November 2017 (UTC)

Hello! Here are my peer review comments, organized by section. I will email you a document with proposed grammatical edits.

Lead: (1) I have made some changes to the list of stages in the first paragraph of the lead to edit for parallel structure, which I have emailed to you in a separate document. (2) In the second paragraph, I think you could provide a little less detail about the role of hair in society as that section is a little wordy and distracts from the main focus of the article, the follicles themselves. I have provided a sample edit in the attached document.

Skin Anatomy: I think that your language becomes a bit too technical for a typical wikipedia audience. When you give examples of the difference in distribution/density of hair follicles, your point is very clear. However, the use of the word "topographical" in the preceding sentence is probably more technical than necessary.

Diseases of the hair follicle: (1) I think that it would be appropriate to add a short lead section here stating that there are a variety of diseases affecting the follicle and maybe giving some broad categories, as the pictures in the section only show a few diseases. (2) Adding links to these different diseases listed would be useful.

General comments: This article is lacking more treatments for diseases affecting the follicle. However, this is an article about the hair follicle itself, not diseases of the hair follicle, so further discussion of treatments for diseases of the hair follicle may be better left to a separate wiki page. If that is the direction that you go, I think a better title for the section about hair transplantation would be something like "Uses/roles in medical treatment of disease."

Hair growth cycle times

Can someone add more? Is this possible? It would be good for the readers to know the average phase or time of hair growth in other parts of the body. — Preceding unsigned comment added by Talaga87 (talk • contribs) 07:28, 28 March 2011 (UTC)

Image:Skin.jpg

Hello!

This bot has detected that this page contains an image, Image:Skin.jpg, in a raster format. A replacement is available as a Scalable vector graphic (SVG) at File:Skin.svg. If the replacement image is suitable please edit the article to use the vector version. Scalable vector graphics should be used in preference to raster for images that can easily represented in a vector graphic format. If this bot is in error, you may leave a bug report at its talk page Thanks SVnaGBot1 (talk) 09:58, 26 April 2009 (UTC)

Club Hair

The link to define "club hair" is external. The guidelines state that an article should be understandable without having to leave the site (paraphrased). I can understand the general idea of the article, but to say that the hair is converted to a club hair, without us knowing what a club hair is, leaves a hole in that understanding, and, I think, indicates one in this article.

Feathers

I was reading about birds (great article by the way!) and when I got to the part about feather follicles, I went What's That? So I clicked on the link and here it is talking about hair and not a feather in sight!

I'm thinking we should create a new section.

Blacklisted Links Found on the Main Page

Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessarily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request it's removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true. Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

Below is a list of links that were found on the main page:

• http://www.healthyhairhighlights.com/stress-and-hair-loss.html

  Triggered by \bhealthyhairhighlights\.com\b on the local blacklist

If you would like me to provide more information on the talk page, contact User:Cyberpower678 and ask him to program me with more info.

From your friendly hard working bot.—cyberbot II ^Notify_Online 15:53, 8 December 2013 (UTC)

 Resolved This issue has been resolved, and I have therefore removed the tag, if not already done. No further action is necessary.—cyberbot II ^Notify_Online 20:07, 25 December 2013 (UTC)

Ethnicity

Removed "african-american" from ethnicity. Unless you are going to exclude the list to include Carribbean, Afro-Carribbean, Black British, French African, etc etf this is ap ointless and american-centric — Preceding unsigned comment added by 31.185.51.254 (talk) 20:23, 19 June 2018 (UTC)

Merge Human hair growth into this?

The section "Hair Growth" has basically everything in Human hair growth except for the part about chemotherapy, which could easily be incorporated under "Disease". Non-human hair growth isn't even discussed in this article. I propose turning that article into a redirect to this, more complete, one. SilverbackNet ^talk 21:54, 13 September 2019 (UTC)

Mapleholistics.com citation for hair loss is promotional and unreliable

"More than 60% of men and 10% of women suffer from hair loss." This section cites https://www.mapleholistics.com/blog/clarifying-shampoo-explained/, which is a post promoting clarifying shampoo on the manufacturer's webstore. The percentage figures themselves are included on the page but there is no source provided. Therefore, this is probably WP:SPS (promotional), WP:NOTRS.

Somebody more knowledgeable should either find a reliable source for the percentages, or remove the mention entirely. — Preceding unsigned comment added by 2001:14BA:300:0:C097:D906:B508:903D (talk) 11:34, 7 March 2021 (UTC)

 Done - I researched actual percentages from medical journals and it's all across the board. Removed mention entirely.  • Bobsd •  (talk) 18:57, 6 January 2023 (UTC)

Order of phases

In the lede, it states "The first stage is called anagen and is the active growth phase, telogen is the resting stage, catagen is the regression of the hair follicle phase, exogen is the active shedding of hair phase and lastly kenogen is the phase between the empty hair follicle and the growth of new hair."

In the Hair Growth section, it states: "Hair grows in cycles of various phases: anagen is the growth phase; catagen is the involuting or regressing phase; and telogen, the resting or quiescent phase". Also, "At the end of the anagen phase an unknown signal causes the follicle to go into the catagen phase. "

I believe that the categen phase comes after the anagen phase and the list of phases in the lede should be adjusted to match.

If no objections, I'll make that change in a week or so.  • Bobsd •  (talk) 00:01, 21 December 2022 (UTC)
