I'm afraid that I can't answer any of your questions, but thank you for posting this information! 

Good to know when someone is working with hair. Really interested if anyone has the answers. 

Also, to add on another question, does toxicity vary from children to adults? For instance, depending on possible absorption or toxicity are some hair adhesives safe for adults but not for children?

Cells are generally replaced --except most neurons-- because they are the functional units. Chromosomes aren't. Chromosomes are packages of genetic material in gametes, which are haploid cells --some kind of random selection of half the organism's genes. Gametes in males are very much expendable. In females, they are more costly, but still. Gametes are cells for export, so to speak --I mean sex--, so they don't need to be replaced.

When cells release stress signals --chemicals that inform about something not being quite right in them-- they are disposed of, so you can imagine that the genetic material inside is at least as expendable.

I hope that helped. This is kind of my lowdown of the story. An expert will give you a more accurate picture.

Edit: Welcome to the forums, Salik.

When you say "functional units" is that referring to how neurons need to be connected to carry signals?

I was just remarking 🙄

It's still a fascinating concept, though, the idea could we someday build a cell? Although would it ever be necessary?

“Our results suggest that direct RF heating of the skin only contributes a small part of the temperature rise and that most is due to heat conduction from the handset.”

It’s in the abstract of your link.

If you put a warm slab of material next to your skin, the skin temperature will go up. Conduction and insulation.

I find this so interesting as to how our bodies react to stimulation. A podcast I have been listening to promotes a device that helps people with temperature regulation simply by emitting a cooling or heating effect which really does help people adjust to uncomfortable temperatures. Mind over matter or whatever.
