Dr. Michael Rendl — Mesenchymal Control of Hair Follicle Growth

On this blog, I have in the past discussed various dermatological associations and non-profits, including several important ones in the United States such as the American Academy of Dermatology (AAD) and Advancing Innovation in Dermatology (AID).  A third one called the Society for Investigative Dermatology (SID) recently had its 75th annual meeting on May 11th, 2016.

SID 75th Annual Meeting

On SID’s youtube channel, you can find a number of the video presentations from this meeting, including a few that discuss hair in at least part of the presentation.  On SID’s website they have a summary list of presentations that includes quite a few involving hair, but none of those videos seem to be available as yet.  Hopefully they will make more of them publicly available soon assuming they videotaped all the presentations.

Dr. Michael Rendl

For now, the most relevant video when it comes to our cause is a presentation by Dr. Michael Rendl that I have embedded below.  On this blog, I have discussed Dr. Rendl’s work several times in the past, including in this post about his Rendl lab.  The below video is highly interesting, especially when it comes to the crucial dermal papilla cell and its induction of hair growth.  I did not realize how complicated this process is and how researchers still have so many uncertainties about the various signals, transcription factors, pathways and processes that lead to the dermal papilla inducing hair growth.

The parts on gene expression, RNA deep-sequencing and CRISPR-mediated genome editing are also very interesting, especially since CRISPR has been in the news so much in the past year (and it now seems inevitable that adult humans will be able to have their genes edited in the future).  A lot of the content is very technical and way above my head.

Kudos to Dr. Rendl for creating the hair-GEL (gene expression library) website for sharing this crucial information with everyone for free. It is too bad that Dr. Rendl is totally bald and seems to be very comfortable with that look.

 

Would you ever Wear a Hairpiece or Hair System?

This year, I plan to conduct some polls on this blog. I also plan to cover topics such as hair transplants and hairpieces more frequently. For many people, these options are almost as good as a hair loss cure and I have received a few requests for more posts on such subjects.

As always, if you do not like a post, just comment on other ones instead.  Women should vote too in spite of the below Elton John image.  I think far more women wear fake hair than do men. Insulting comments will be deleted.

Update: I had to delete the poll in 2018 due to some plugin issues. The results of the poll are summarized below.

Update: 2022 — Lately, there have been some great before and after  toupee or hairpiece videos on TikTok, YouTube and Reddit.

Would you ever wear a customized hairpiece or hair system or toupee?

Total responses = 1,526.

Yes = 396 (26.0%).

No = 854 (56.0%).

Maybe = 276 (18.0%).
