Only people who think they know what they are talking about BUT actually DON'T KNOW what their talking about say things like you say.
FYI, you don't even need to know the exact Molecular signals to turn on and off to combat hairloss at its specific pathways.
They just need to return the cells in the scalp to a younger state, at which time the follicles were strong enough to combat hairloss.
Some of the richest people in the world, and the most successful businesses and people are working on this exact concept.
For example, Turn Biotechnologies is working on using this concept but in the hope to be a cure or amazing treatment for Hairloss.
David Sinclair, is also working to restore cells to a younger state and also is working on hair.
The 2nd richest man in the world Jeff Bezos, is working with another billionaire, Yuri Milner, to return cells to a younger state. Their company is called Atlos Labs.
Also, if you're concerned with off-targets you should really do your research before talking and find out just how much Gene Editing has advanced just this year alone.
They went from only having Cas-9, to CRISPRoff and CRISPRon.
In a paper published April 9, 2021, in the journal
Cell, researchers at UC San Francisco and the Whitehead Institute describe a novel CRISPR-based tool called “CRISPRoff,” which allows scientists to switch off almost any gene in human cells without making a single edit to the genetic code. The researchers also show that once a gene is switched off, it remains inert in the cell’s descendants for hundreds of generations, unless it is switched back on with a complementary tool called CRISPRon, also described in the paper.
Because the epigenome plays a central role in many diseases, from viral infection to cancer, CRISPRoff technology may one day lead to powerful epigenetic therapies. And since this approach doesn’t involve any DNA edits, it’s likely to be safer than conventional CRISPR therapeutics, which have been known to cause unwanted and potentially harmful changes to the genome.
There's even Cas-12f or Cas14 and Cas-13
Theres also a lot more advancements.
I have no doubt that in the near future we will atleast see a very good Gene Based treatment for Hairloss.
