There are a HELL of alot more effective and cheaper products out there. There are a million and 1 hair products out there like the one you found, all with great before and after pics and SEEM cool... but they all charge an arm and a leg, and very few truely work well. The few products out there that are scientifically proven and known to work are finasteride, dutasteride, minoxidil (which I would not recommend... if you start taking it, your on it for life) nizoral 2% shampoo and topical spironolactone 5% cream (get it from a reputable company... some forms of spiro can go systemic instead of just staying in your scalp, which you DON'T want...). All other products out there contain some form of those ingredients, or a combination of them.... just with a much heftier price tag. Also, the Lazer Comb has actually scientifically been shown to re-grow hair due to increased circulation... you can find it for pretty cheap... I got mine for 50.00 and it works great. Good luck
