Since when, back in 1990, my barber has been using it. a haemostatic pencil (not disposable) after a razor cut right on my nape. I totally agree with you that almost no barber respects the protocols that by law should respect. For example, I also consider the razor blade potentially at risk of contagion, for the simple fact that if there is one; a cut the blood does not end only on the blade, but also on the blade holder.
It is my opinion that even the comb, if used vigorously, can “scratch” the scalp, with consequent micro-lesions.
On the UV sterilizer we then spread a piteous veil. According to me & egrave; it was only a legislative content, given the near impossibility; practice to provide more disinfection and sterilization equipment for barbers; effective. Typically in the dental field (but also in other fields) that type of sterilizer only serves to maintain sterile materials that already exist; they are.
This is because & eacute; the power of penetration of UV rays is clear; quite superficial. As long as there is a micro-drop of blood on scissors or combs because its sterilizing power is completely ineffective.
Moreover, in any sterilization protocol it is written that the irons or materials must be CLEAN before being sterilized. I do not think this is done by scissors, combs, brushes and so on. And it does not come to me to say that long-term clinical studies have been carried out from which it turned out that mine are only paranoia. I challenge any researcher to set up a research on the specific barber risk.
Whoever claims that the risk is nonetheless is based on dynamics studied for other situations at risk, above all sexual or surgical, not on the barber and on the problems deriving from it. Therefore memorize options even their opinions are the result of reasoning translated from other scenarios, not the result of specific studies. At least I do not have any. But even if such studies were done, I can not even hypothesize what kind of procedures they used, how they selected people, etc. etc. So since I too, for the studies I have done and the profession that I carry out I can hypothesize by making some reasoning, I am of the opinion that prudence is not; never too much.
I would not trust, so to speak, even the electric razor. Unless (to give an example of how I think), a study of the use of electric razors does not prove to me that the contagion is; impossible 100% (mind you, 100%, not 99.99%.) I do not see why because I should risk only 0.01%, if I can avoid it.). That said, I explain how I solved the problem. From that day on which they used the haemostatic pencil, I go to the fully equipped barbershop. I bought scissors, razor, comb, brush (all professional) and (obviously) hemostatic pencil, and every time I go I use them ONLY my tools.
My barber knows perfectly well that this is; the only way to have me as a customer. As for the test, I did it, to get the worry out of my mind. You can; adjust as you see fit, but if you can not feel comfortable I suggest you do it.
