I've tried Talika in the past, and NOP it doesn't work. Don't bother on wasting your money on it. I just started using LILASH for a week, and I can tell you it's working. No irritation whatsoever, I only got a bit of pink eyed on the 1st day and it subsided completely on 3rd day until now. I don't think those cheaper version one will works miracle. Mostly it will just condition your lashes. I've done a lot of research before purchasing LIlash. A friend of mine who is using Jan Marini lash, she recommended me Lilash instead. It worked great on her friends, too. I've read good customer reviews of Lilash as well, 2nd in place Jan Marini. But the newer version might work might not like the old original one. I've read mix review of Revitalash, so I skipped it. I've seen real photos of Revitalash on some people. They do work, but also there's side effects, something like that. Hope it helps.
