I've tried a lot of different eyelash enhancing products, and researched them all to death! FLash really does work, and for half of the price of most other products on the market. Its important to realise that it doesnt work over night - but if you are patient and continue to apply it every day, you will begin to see a difference after a couple of weeks. After 4-6 weeks of using it, other people were beginning to comment on the length and fullness of my lashes. I now just use FLash to maintain my long lashes - its a great product, and offers great value for money when you compare it to other brands!
