Hair today, gone tomorrow. Do not let any nasty or insensitive person make fun of your sudden or drastic loss of hair. But you may be sensitive and it is looking likely that this hair loss could be permanent. There is only one way to know this for certain. Seek out a medical opinion from a specialist practitioner or a clinical diagnosis from a hair remediation clinic. In the latter case, your consulting technician could prescribe what is being called platelet rich plasma treatment.
Or PRP treatment for short. Now, what this treatment process entails is the actual sampling of your own blood, quite literally so. But you need not have been worried because the procedures are quite safe. They are also non-invasive and there is very little chance, if any at all, of the patient suffering from any harmful side effects. About the worst side effect that could be suffered is that no hair will be growing.
That, of course, is not the fault of the procedure. Even PRP will have its limitations. The specialist techniques and the operating equipment being used by the qualified clinician can, really, only go so far. You are all human. And so are they. The point is, that the failure of hair growth is likely due to extremes, such as in the case of advanced states of illnesses and diseases where both medical practitioners and their patients would have to tread very lightly indeed.
Treat lightly the hair remediation clinician will too. You will hardly feel a thing. The treatment regime does, however, require several sessions that will run over a period of weeks, perhaps a couple of months. And thereafter, the clinician would still need to carry out routine inspections to ensure that the hair growth remains healthy and safe.
