Great service - even in difficult times! For some reason, we can't get this in my country - I have no idea why! I bought this on a trip overseas and used daily and felt a real difference with both my hair and nail growth. I wonder why it's such a kept secret? No side effects, only great, shiny strong hair and long strong nails... and a healthy metabolism... best recommendation I received in the past few years. I recommend to anyone looking to feel a bit better. I'll be reordering for sure!
