Ingredients and Tools(how to do a soap cap with hair color)

Alright, let’s gather the essentials for your soap cap adventure. Here’s what you’ll need:



Choose a volume based on your goal (e.g., 10 vol for minimal lift, 20 vol for moderate lift). This is the magic potion that activates the hair color.


Opt for a gentle, color-safe shampoo. This will be the base of your soap cap mixture, so choose one that won’t strip your hair.

Hair Color:

Pick a hair color that suits your desired outcome. Whether you’re maintaining your current shade or experimenting with a new one, choose a quality color product.


Mixing Bowl:

Grab a non-metallic bowl for blending your ingredients. Metal can react with the chemicals in the mixture, and we want the magic to happen on your hair, not in the bowl.

Applicator Brush:

A brush makes applying the soap cap much easier and helps ensure even coverage. Choose one with soft bristles for a smooth application.


Protect those hands! Gloves are a must to shield your skin from the color mixture. Disposable ones work like a charm.


Whether it’s on your phone or a good old kitchen timer, make sure you have something to keep track of the processing time. Timing is key for that perfect outcome.

Sectioning Clips:

If you’re working with long hair, sectioning clips will be your best friend. They help you divide your hair into manageable sections for even application.

Selecting the Hair Color(how to do a soap cap with hair color)

Now comes the fun part – choosing the right hair color for your soap cap! Whether you’re looking to enhance your current shade, tone down brassiness, or dip your toes into a new hue, here’s how to pick the perfect color:

Consider Your Current Shade:

If you’re aiming to maintain or enhance your existing color, choose a shade that closely matches or is slightly lighter than your current one. This ensures a subtle and natural result.

Toning Goals:

For toning purposes, select a hair color that complements your desired tone. If you’re battling brassiness, opt for a cool or ash-toned color. To warm things up, go for a warmer hue.

Lightening Intentions:

If you’re using the soap cap for a gentle lightening effect, choose a color that aligns with the level of lightness you’re aiming for. Keep in mind that the developer’s volume also plays a role in this process.

Experimenting with New Shades:

Feeling adventurous? The soap cap is a fantastic way to test the waters with a new color without committing to a full dye job. Choose a shade that excites you but won’t shock you!

Brand Reliability:

Stick to reputable hair color brands. Quality matters when it comes to achieving the desired results and maintaining the health of your hair.

Patch Test:

Before diving in, perform a patch test to ensure you’re happy with the color and to check for any allergic reactions. It’s a small step that can save you from potential discomfort later.

Preparing the Mixture(how to do a soap cap with hair color)

Alright, let’s whip up the perfect potion for your hair glow-up – the soap cap mix. It’s like making magic happen, but for your locks! Here’s how to get it just right:

What You Need:

Developer: Grab the developer based on how much change you’re after. Low volume (like 10 vol) for a subtle tweak, higher volume (around 20 vol) for a bit more oomph.

Shampoo: Get your hands on a gentle shampoo. This is going to dilute the color, making it kinder to your hair.

Hair Color: Pick the color you’re vibing with. The amount depends on your hair length and thickness, so start easy and adjust as you go.

Mixing It Up:

Bowl Choice: Use a non-metallic bowl. Metal and this mix aren’t besties – we want the magic on your hair, not in the bowl.

Blend Away: Mix everything up until it’s smooth like a good yogurt. No lumps, no bumps – just pure creamy goodness.

Thickness Check: Check the texture. Too thick? Add a bit more shampoo. Too thin? Toss in a smidge more hair color. Aim for that perfect creamy consistency.

Application Technique(how to do a soap cap with hair color)

Okay, time to get hands-on with that soap cap magic! Here’s your go-to guide for a flawless application:

1. Divide and Conquer:

Clip your hair into sections. This makes sure you get an even application without missing any strands.

2. Glove Up:

Slip on those gloves – we’re diving into the color fun!

3. Roots First:

Start at the roots, especially if you’re doing a touch-up. Precision is the name of the game, so use that applicator brush like a pro.

4. Work It Down:

Spread the love! Work the soap cap down the length of your hair, making sure every strand gets a piece of the action.

5. Target the Troublemakers:

Got spots that need extra attention? Hit those trouble areas with a bit more soap cap to even things out.

6. Comb Through:

Grab a wide-tooth comb and gently comb through. This ensures every strand is coated and ready for a color transformation.

7. Mirror Check:

Quick mirror check – don’t forget the back! We’re going for perfection here.

8. Set the Timer:

Timer’s up! Set it based on your hair’s needs, and let the soap cap work its magic.

9. Keep Time in Check:

Peek at the clock now and then. We don’t want to overdo it; happy hair is the goal!

10. Rinse and Shine:

Time to wash out the soap cap. Use a gentle shampoo, and follow up with a conditioner for that extra TLC.


Q1: What’s the deal with a soap cap, and how is it different from regular hair coloring?

A soap cap is like the laid-back version of hair coloring. Instead of going full throttle, it’s a mix of hair color, developer, and shampoo, giving you a more chill color vibe. It’s perfect for subtle changes or refreshing your current look without the full commitment of a dye job.

Q2: Can I grab any shampoo for the soap cap mix?

You’ll want to go for a gentle, color-safe shampoo. Think of it as the wingman to your color journey, making sure things go smoothly. Steer clear of clarifying shampoos – they can be a bit too intense.

Q3: How do I pick the right developer for my soap cap?

Think about your end game. Lower volumes (like 10 vol) give a gentle lift, while higher volumes (around 20 vol) go for the gold. It’s all about what your hair needs and how much lightening you’re aiming for.

Q4: Can I soap cap my already colored hair?

Absolutely! It’s like a spa day for your existing color. Match your current shade or go for a toning shade to fight off any brassy vibes.

Q5: How long should this soap cap party last on my hair?

Timing is everything – usually between 10 to 30 minutes. Follow the instructions on your hair color product and, when in doubt, do a little strand test.

Q6: Can I hit up my hair with a soap cap when it’s dry?

It’s better to catch your hair in its damp phase for this party. Moisture helps the color spread evenly. You can either dampen your hair with water or go for it right after washing
