How to draw mermaid hair

Mermaids are beautiful.

And drawing mermaids is such an excellent way to pass the time.

However, drawing a mermaid’s hair can be challenging because there is a lot of physics involved.

Especially if you’re looking to understand how to draw mermaid hair underwater or want some references for mermaid hair drawings.

I’ve made another post on drawing wet hair if you’re interested.

I will specifically teach you how to draw mermaid hair flowing underwater and even out of water in this post.

I want also to include a mermaid who is half in water and half outside so that I can show you how to draw wet and dry hair.

Learn how to draw mermaid hair. This is an easy step by step tutorial for beginners. Includes multiple mermaid hair drawings.

I will even show you how I color mermaid hair step by step in Procreate because there aren’t that many tutorials online breaking down this information.

Please note that I am currently using an iPad Pro and an Apple Pencil to create all my illustrations. But you can use any tool – a pen and paper, Copic markers or Photoshop because the drawing method remains the same.

Let’s begin.

How to draw mermaid hair

Before I begin with this tutorial, I just want you to keep this in mind:

  • When drawing hair, remember to treat the hair as a whole object.
  • Once you have the basic outline of the shape of the whole hair, you can start dividing it into sections – ribbon-like sections because hair clumps together.
  • After dividing the hair into sections, you can then start working on each section by drawing the strands
  • End with adding the highlights and the shadows!

Okay, so you have the basis.

Let’s begin drawing the mermaid hair!

How to draw mermaid hair (out of the water)

First, we’ll start with a head – this will make it easier to draw the hair. I am using the dry ink brush in Procreate.

Start with the head

I’m drawing this mermaid hair in a cartoon style – you can see this book to learn how to draw characters in a cartoon style.

I’m going to add her body now – she’s propped up on a rock because I want to draw this mermaid as if she’s just come out of the water.

Draw the body of the mermaid

Next, I’m going to make this layer transparent so we can clearly see the mermaid’s hair.

I will start with the overall shape of her hair.

Start with the basic outline of the mermaid's hair

Since her hair is wet, you don’t need to add much volume to her hair. The hair will pretty much be straight and flowing downwards.

Now, I want to add some hair on her shoulders so I’m going to draw that.

Draw in folded sections of hair on her shoulders

When the hair falls on the shoulders, – it flattens a bit because it’s lying on the shoulders. So, remember to vary the volume and density of the hair as it touches the shoulders.

Once the hair falls from the shoulders, the volume decreases again.

Think of drawing this section like a snake – it gets thicker in the middle and slowly decreases in volume as we reach the tail.

I’m going to draw one more section of folded hair on the other shoulder.

Add as many sections as you like

Next, we can draw the ends of the hair – just remember to draw quick strokes here.

Draw the ends of her hair

Next, I’m going to draw strands in her hair. Divide the hair into sections by drawing strands inside each section.

Draw the strands in the direction of the hair flow.

Remember to vary the distance between strands. If it’s parallel, it will look odd.

Divide the sections of hair into strands

This definitely takes some practice, so don’t worry if it doesn’t look perfect.

Keep drawing till you become comfortable with drawing hair.

I’m going to draw all the strands in the sections of the hair now.

Continue to divide the mermaid's hair into sections

And once you’re done, you can draw some stray strands just to make her hair look a little more realistic.

Add stray hairs to the mermaid's hair to make it look more natural

Once you are happy with how your mermaid’s hair looks, finalize the drawing by erasing all the overlapping sections.

And you should get something like this:

Erase all the rough lines

Now, that you have the outline, you can duplicate the layers and group them. Flatten the group so that your entire outline is in one layer and then make it a reference layer so that you can just drag and drop colors in different layers.

I’m going to shade the mermaid’s skin first.

Paint her skin first

And then, I will color her hair with a simple base color – I’m going to go for teal because I love that color so much!

Color the hair with a simple base color first

Now, I’ll add some highlights to her hair in a new layer.

Add the highlights to her hair

And finally, I’ll add in the shadows. I’m going to use the Bonobo brush and go in with a purple shade.

Add dark purple shadow to her hair

And once I’m happy with the shadows, I’m just going to change the blending mode to multiply and decrease the opacity to 35%.

Change the blending mode and opacity of the shadow layer

And voila!

We’ve finished learning how to draw mermaid hair out of the water.

If you are looking to learn how to draw a mermaid on a rock, see this post.

Okay, but what if she’s half out and half of her hair is submerged underwater?

Let’s learn how to draw that!

How to draw mermaid hair (half in water)

Okay, let’s begin with the head shape as usual. I’ll even add in the shoulders.

If you’re having difficulty drawing head shapes, pick up these great character builder brushes from Procreate.

Draw the head and shoulders

Next, I’m going to start with the head shape.

Now, because half of the mermaid’s head is above water – her hair will be wet and sticking to her head.

This means I need to make sure that the volume of the hair is less because it’s sticking to her head on the top.

Start with the basic shape of the hair

Now, the remainder of the hair is underwater, so her hair will be flowing in the water.

When drawing these sections, remember to keep the hair very fluid – draw large S shapes with varying volumes to make it look more natural.

Let me show you what I mean.

Draw sections of the hair in water

Remember that the hair decreases in volume and density as we reach the ends.

It’s best to draw the hair with long strokes. It can take some practice moving your wrists to draw these long strokes, but it does get easier if you spend more time practicing drawing hair.

Let’s do more sections.

Continue drawing more sections of hair

You can vary the degrees of the hair sections too. In this case, the strand is moving away from her in a backward direction. As you get to the end of the hair, the loop becomes more angled.

Now, let’s finish this section.

Remember to vary the thickness of the hair

I’m going to draw one more section in front of her shoulder.

Draw more sections of the mermaid's hair

Now, I’m going to divide all these sections into strands, just like before.

Divide the hair into sections

And, I will erase all the rough lines so that I get a nice, clean outline of the mermaid’s hair.

Erase all the rough lines

Now, let’s quickly color the mermaid’s skin.

Color the skin tone

And I’m going to use the same teal base color for the hair as before.

Add the base color of the hair

And I’ll add in the shadows – I’m going to use the same process as before.

Add shadows to her hair

Next, I’m going to go in with the highlights.

Add the highlights to her hair

It already looks amazing.

But this mermaid hair drawing will look so much better if we add in the water.

So, on a new layer, I will paint a blue portion and then decrease the opacity to 50% so that the layer is transparent and we can see the mermaid in the water. Now on a new layer, I’ll add some white strokes to add more texture to the water’s surface.

So, we should get something like this:

Draw the water over the hair

And we have learned how to draw a mermaid’s hair in water while it is half in water.

How to draw mermaid hair underwater

So far, we’ve learned how to draw mermaid hair out of the water and half submerged in water.

But what if she is in water entirely?

Do the dynamics change?


You have to consider the water current and the movement of the mermaid underwater, especially when you are drawing long hair underwater.

If she is stationary, you can draw her hair flowing in the water in basically any direction.

It doesn’t matter.

But it is important to maintain that fluidity, to make it look like her hair is flowing smoothly.

Think of each section of the hair as a ribbon flowing gently in the water.

Let’s begin with her head first.

Draw the head

Let’s start with one section first.

Pencil Pack Procreate Brushes
Divide the mermaid's hair into sections moving upward.

Note how the hair volume decreases as we reach the ends of the hair.

This is important and just by implementing this tip, you will be able to make your mermaid hair look very real realistic and organic.

Okay, let’s continue with more sections.

Draw more sections of the hair

It can get a little confusing, but it is important to remember that all the hair should move in 1 general direction.

In this case, I’m drawing the hair moving upwards.

Hair is lighter than the body so it can flow in any direction.

Once you’re happy with how your hair shape looks, you can start drawing the strands.

Take your time with this and do it section by section.

Divide the hair into strands

Make sure that the strands start from the mermaid’s scalp and move toward the ends of the hair.

Try to use long fluid and singular strokes when moving your hand across the canvas.

I’m going to go in and draw more strands.

Draw more strands

Now, it’s time to draw the tips of the hair. I’m going to draw the tips in the opposite direction just to make the long hair look more organic and make the mermaid’s hair look like it’s floating in the water.

Curve the tips of the mermaid's hair

I feel it’s pretty much complete, so I’m going to erase all the rough lines and finalize the outline.

Erase all the rough lines

And now, I will go in with the same base color as before for the mermaid’s hair.

Color the skin and add the basic hair color

And I will draw the shadows.

Add in the shadows

I will change the blending mode and opacity of the shadow layer.

Change the blending mode of the layer

And finally, I will go in with the highlights to complete drawing this long hair underwater!

Add in the highlights

Drawing hair can be a little challenging – especially if you are drawing mermaid hair underwater.

The physics changes so it’s an all-new learning experience.

But drawing hair does get much more manageable with more practice. Trust me. Also, drawing with references helps! You can look at stock photos of hair underwater or see illustrations of mermaids on Pinterest just to see how different artists draw hair.

One of the best parts about drawing hair in a cartoon style is that you don’t need to complicate things by adding too much texture. You just have to get the shape right and draw a few lines in the direction of hair growth.

I have a post that you can read on how to find your art style if you are keen on developing your own style of drawing cartoons.
