These are some of the top coats and nail hardeners I've tried and hope to try.

Sally Hansen Mega Shine is my favourite top coat of all time! It dries quickly and gives your manicure an amazing shine. It doesn't dull down. That Mega Shine is continuous.

Sally Hansen Diamond Shine was the first ever top coat I used from the line and instant became a favourite. It dried quickly and gave my nails a glass like shine. The shine is not as intense as Mega Shine but it's just as great.

Seche Vite it was ok! I don't think I'll be purchasing it again! I didn't see what all the hype was about. I prefer the Mega Shine. I hated how thick and goopy it got halfway through using and I know you can buy the thinner but I think that's just a waste to be honest. A good top coat should last, especially for the price.

Prolana Nail Optimizer this is the nail hardener I'm currently using since I can't find my favourite one anymore. It's good! It gets the job done! Nothing life changing. Lol

Sally Hansen Insta-Dri it's okay. Not as good as my two favourites. :-) 

All the other polishes I haven't mentioned I can't wait to try. Do keep a look out for reviews. You can find all these polishes on ebay, amazon or your local beauty supply store. :-)
