Steps for Hair

Step 1
To get a perfect mermaid hair style, begin this tutorial with a clean, dry mane and brush through your hair to remove any tangles or knots. Separate the sections of your hair you want to colour and tie back the rest to keep it out of the way. Comb out a small section of hair and apply L’Oréal Paris Colorista Hair Makeup in #Purple50 with your hands, applying it evenly to your locks. Take the other sections of your hair and repeat application with colours #Blue60 and #Green70.

Step 2
To set your Colorista Hair Makeup shades, add heat to your strands by zapping them for a few minutes with your blow dryer. Use any hot tools to style your hair into your desired look.

Steps for Eyes

Step 1
The first step in achieving a beautiful mermaid makeup look is to start with bare, prepped eyelids. Using a fluffy eyeshadow brush, apply Infallible Eyeshadow in Always Pearly Pink to your upper eyelid and blend upwards and out for a soft halo of colour around your eyes.

Step 2
To add definition to your eyes, line your upper lash line with Infallible Long Wear Eye Pencil in Purple. At the outer corner of your eye, apply a small upwards flick with your eyeliner to get a subtle cat eye. This will open up your eyes and really make them pop.

Step 3
Tie your aquatic eye makeup look together by applying Voluminous Extra-Volume Collagen Mascara in Blackest Black to your upper and lower lashes. Layer on a second coat for full, fan-like lashes.

Steps for Face

Step 1
The last step in the mermaid tutorial is your face makeup. Using a fluffy blush brush, buff Colour Riche Eyeshadow in Green Promenade into your temples, around your eyes and above your cheekbone in a ‘v’ shape. You can apply a couple layers of colour to make the look as dramatic or soft as you’d like.

Step 2
Next comes the transformation step to take your mermaid makeup to the next level. Using Voluminous Lash Paradise Liquid Liner in Rose Gold, draw small mermaid scales on top of your eyeshadow and around your eyes.

Step 3
Get glowing by highlighting the inner corners of your eyes, chin, nose and cupid’s bow with the Infallible Galaxy Stick in Astro Blue.

Step 4
Your look is almost complete. Top off your shimmering beauty look by swiping on a coat of Infallible 2-Step Lip Colour in Lilac Infinite.

And just like that, you’ve created a mermaid makeup masterpiece! Use this tutorial as a guideline but don’t be afraid to get creative with it. You can play around with different colours for your scales or shades of eyeshadow to really customize the look or add a touch of extra glitz by layering on a little glitter.
