I have had general have diffuse thinning on the top and wide hair parting . In general my hair has lost its thickness and voulme. I took viviscal, tried nioxin and all other hair boosting methods. I got my thyroid checked b12 etc. I started low light laser treatment and then added my first PRP on march 4h. My next PRP was April 28th. At this I am not certain if it has made a difference yet...
