So first you're gonna grab your eyebrow pencil. I'm using one that has the same undertones as my hair but is quite a bit lighter. If you have dark hair, it's best to use a pencil a few shades lighter than you haircolour and if you have light hair it's better to go a few shades darker. This is if you want a natural effect though, you can of course choose whichever colour you fancy. Have pink brows if that's what you want! Pink brows are awesome.
If you have medium coloured hair you should make your own educated guess as to whether you should pick a lighter or darker shade. Also, I also advice you against picking an eyebrow pencil with a warm undertone unless you have similar colouring to me. On most people it looks a bit weird though, so try to go for cool colours like taupe, grey or dusty browns.
Step 1: Define your shape
What you do is you very gently trace the shape you want your eyebrow to be. There's several ways you can do this, I like to use the natural growth of my brows as a guideline. We start out this way because it makes it a lot easier to follow later. Make sure that you don't draw harsh lines, especially on top. The bottom area of the eyebrow is usually a bit fuller, so it's okay if that looks more defined versus the upper area.
The Golden Ratio is a guideline as to where your arch should be, where your eyebrows should generally begin and also where they should stop. This guideline has proven to be flattering for most people, but keep in mind that it's still a guideline. It's not a rule! If it doesn't work for you, ditch it and try other things. This method doesn't really work for me - It gave me some serious case of Disney Villain brows - so I made up my own shape and just roll with it. Every face is different, keep that in mind.
Step 2: Fill in lightly with eyebrow pencil
With the same eyebrow pencil, proceed to slowly and gently fill in your brow. Use small brush strokes, you want it to look as if you're drawing small hairs. Also make sure that the beginning of the brow doesn't look harsh. Harsh, blocky looking brows are a dead giveway and makes them look very drawn on. Don't do it except if that's the look you are going for. I also think it makes the face look too severe and frown-y, so I prefer a subtle start to the brow.
Step 3: Light powder
Now choose a light neutral toned matte colour, a few shades lighter than your eyebrow pencil. I'm using Naked from Urban Decay's Naked palette. This is the lightest shade we'll use.
Gently push the angled brush through the first part of the eyebrow. We're going to achieve a subtle gradient effect here. I do this because it gives the brow a lot more depth and definition, it makes it look a lot more realistic because you're imitating the way real brows are constructed. People with full brows often have the most fullness in the middle and on the bottom half of the eyebrow. This is what we're going to simulate.
Step 4: Darker powder
We're going to make the brows look a bit more defined by choosing an eyeshadow colour a few shades darker than you eyebrow pencil. I'm using Buck from the Naked palette.
Carefully work the colour through the part of the brow illustrated above. This will give the illusion of fuller, more defined brows.
Step 5: Finishing touches
For lighter looks I often call it a day by the end of step 4, but for a little extra definition I like to use a cool toned darker shade. For me, Maybelline's Colour Tattoo in Tough as Taupe is perfect.
This step is similar to the one before, only now you try to define the bottom edges of your eyebrows. Also put some in the middle to give the illusion of thickness. As you can see, the gradient effect is definitely there now but still subtle enough to make it wearable.
With your spoolie, very gently go through your brows. Make sure that the colours are blended. Be super careful though! If you press too hard it's very easy to make your brows look muddy and smudged. Try to prevent that.
As a final touch, I like to spray some hairspray on my spoolie and very carefully go through my now finished eyebrows with it. This will set the powder and keep the hairs in place all day. You could also use an eyebrow gel instead, whichever you prefer.
So, this is what my brows looked like before. Very sparse, zero definition and a bit of a no-show honestly.
And this is what they look like when I'm done! It's a lot of fuss to go through for just your eyebrows, I realise that. It's also the thing that ends up looking the best though, and for that it's well worth it. I hope this tutorial helped you a bit and gave you some ideas as to what to do with your brows. Good luck!
