Dear tommy10,Androgen blockade is one of several medical therapeuticinterventions for patients suffering from male pattern hair loss. Androgen blockade, through the use ofpropecia, proscar, finesteride or dusteride will reduce the amount ofcirculating androgen that circulates locally in the scalp and, as a result,there will be less androgen converted to dihydrotestosterone from the relativeenzymatic deficiency that exists. Dusteride is not FDA-cleared for hair loss. There are some studies that do suggest thatat higher levels, it may be more effective than finesteride, but this wouldhave to be prescribed to you off-label here in Canada. In general, it is important to realize whenusing androgen blockade there are several side effects that need to beconsidered. There is some loss of libidoand reduced sexual function. There maybe potential for permanently reducing the sperm count, especially in dusteridepatients. There are some papers thatshow that a small subset of patients may be at higher risk for prostate cancerusing androgen blockers for benign prostatic hypertrophy and presumably thatmay be the case for male pattern hair loss. Used in combination – androgen blockade with a vasodilator such as ahigh concentration of minoxidil and high-fluence, low-level light therapy andmedicate shampoos is the four-pronged attack to nonsurgical male pattern hairloss. Because of the side effects ofandrogen blockade, it is very important you seek the expertise of yourphysician prior to embarking. Rememberto always track your prostate-specific antigen Finesteride has more clinicaldata and efficacy in the literature for male pattern hair loss, but dusteridemay be more efficacious at higher doses.At SpaMedica, we have been performing hair restoration withfollicular unit extraction technique for almost seven years, having abandonedthe strip graft surgical technique. NeoGraft® and ARTAS® are the follicularunit automated and robotic devices we use to avoid a linear scarlessapproach to harvest. With aestheticallyartistic implantation, very natural hair transplantation can be achieved. The medical management is often combined withsurgical to try and minimize ongoing hair loss and then the risks and benefitsof the oral and transcutaneous medications need to be reviewed.
