It’s all rather technical — some patented application of Zinc pyrithione — but the proof is in the shampooing. Yes, there are plenty of JFM-sanctioned studies, but why not add one anecdotal application to the mix? In about a month using the shampoo three times a week, the patchy salt and pepper has all but disappeared from this users’s dark wavy hair. When I dialed it down to twice a week — for about a month — a more subtle salt and pepper remains, where I’d like it to stay.

Authority to prescribe an Authority medicine is granted for specific indications and/or for certain patient circumstances. Authority may be obtained by telephone to Medicare Australia (known as "phone approval") or in writing from an authorised delegate of the Minister for Health. Fortunately, there are loads of ways to get out the grey. You can do away with it in one swoop with your classic hair dye that matches your color. This is best if you are ready to own up to a big change or want to do away with it completely and keep it that way. If you’d rather slow the process down, however — or, really, slowly reverse the process — the gradual grey shampoo from Just For Men is your killer tool. Some PBS medications are restricted and require prior approval from Medicare before a doctor is able to prescribe them on the PBS. This prior approval to prescribe grants the doctor the Authority to prescribe the desired medicine and have it funded under the PBS. Prescriptions must be written on an Authority Prescription Form, and the approval number must be noted on the prescription. Pharmacists cannot dispense the item as a pharmaceutical benefit unless it has been approved by Medicare Australia (indicated by the presence of the approval number).Some drugs may have Authority Required (Streamlined) status which does not require an explicit approval from Medicare, instead the doctor can use the Authority code found in the published Schedule for a given drug/indication.
