message: 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)
replies: text: 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)

message: 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)

message: 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.

message: 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.

message: 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.

message: 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)

message: "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)

thread_title:  Mapleholistics.com citation for hair loss is promotional and unreliable 

message: 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)
