Mascara
I usually use Maybelline Colossal Volume, it's really effective, affordable and easy to remove. I also love Benefit's mascaras, but they're a little more expensive.

Blistex Relief Cream
This is my favourite lip balm. It works immediately and doesn't leave your lips sticky, just moisturised and tingling.

Emporio Armani She Perfume
I've been using this perfume for as long as I can remember. My big sister used to wear it and I would sneak into her room and steal a spray when she wasn't looking. I haven't looked back since.

Nioxin Hair Products
My mum recently bought me a set of Nioxin products (shampoo, conditioner, hair mask and protection spray) to protect my hair when I'm performing. Every night my hair is heated, rolled and back combed, which doesn't make for a happy head of hair. My hair feels much stronger and healthier and ready for the rollers since I started using this range.
