Neogenic

[Hairismylife]

I see some ppl use neogenic+Ru combo.
Neogenic can help regrowth?
Where can I buy vichy neogenic except ebay,any official website?
What the difference with L'oreal Neogenic? I heard much criticism of L'oreal before.
Should I apply neogenic first or Ru first if I am not going to mix them up?
Sorry for so many questions.
