Originally I got it done from Milena from beauty medical back in Sept of 2012,this was a quick pass..this was a free session as I nominated myself as they were looking for a few people to show her work,because it was a free session so it was a quick pass,this started to fade about 10 months later,not entirely but the hair line started to fade.
I recently got it touched up from here locally from Hasson and Wong,they have techs who have been trained by Milena herself.
No it does not turn another color when fading,I shave my head every morning.
If you have to get all 3 zones down,front,middle and crown,this should last you 15 months to 2 years.
