There are already clinics offering this in the US and there doesn't seem to be anyone talking about them so i am not sure why everyone is going crazy over Kerastem specifically. One of the clinics is in North Attleborough, MA -
http://www.nehair.com/stem-cells - (774) 643-6126
The process they describe seem to be identical to Kerastem (basically stem cells derived from adipose cells injected into scalp) - they have one test case with photos on the site which is quite impressive in my opinion. Anyways, there are no mentions of costs but they seem to offer it to inquiring patients so i am sure they would be happy to give a quote?
