How to Dye Porous Hair – the Right Way

How to Dye Porous Hair

Dying your hair is one of the best ways to create a bold, new look that can transform your entire appearance. While there are many shades available, ranging from pastels to brights, few people know how to dye porous hair effectively without damaging their strands or creating an odd, uneven effect. 

Hair dyes are designed to give you the shade you want, but they can damage your hair if you don’t dye it correctly. For porous hair, using heat and applying the dye directly to your hair will damage it even more because porous hair absorbs whatever comes into contact with it. To dye porous hair, use as little heat as possible and apply the dye to the hair from a distance so that your hair doesn’t absorb as much dye and thus become damaged.  

Fortunately, you don’t have to learn everything through trial and error; here’s a comprehensive guide on dyeing porous hair that will help you avoid common mistakes and give you beautiful results every time!

Keep reading for more info about what the ingredients are included in products with zero ammonia and why these ingredients work better than other options like bleach or peroxide.

What Is Hair Porosity?

Hair porosity refers to how much air and water can travel through a strand of hair. The general rule of thumb is that coarse, curly, or damaged hair has a higher porosity than straight or fine hair. Stylists and consumers alike need to understand their porosity level since it affects everything from color selection to product choice (more on that later). Because porous strands are susceptible to damage, special measures are taken before and after any color job.

How does it affect your hair color?

How to Dye Porous Hair

A person’s hair porosity affects the ability of their hair to hold onto moisture. Their hair porosity may vary depending on factors like the person’s natural texture, styling, environmental exposure, and color history. Healthy hair typically has a hard layer of coating that protects the hair from damage from exposure to chemicals, heat, and saltwater. 

Exposure to these things can cause the hair to be porous. When hair is weakened, the cuticles of the hair shafts may get frayed and lifted, causing them to be porous. In cases of high porosity hair, dyes penetrate too quickly into the hair shaft and cause additional damage to the hair. Low porosity hair prevents water, conditioners, and dye from penetrating the hair shaft. As a result, low porosity hair requires more time for the dye to produce a vibrant result.

How To Test The Porosity Of Your Hair

An essential part of making sure you’re ready for dye is testing your hair’s porosity. The test will allow you to measure whether or not you have any weak spots in your hair that would be extra vulnerable to damage if you tried coloring it at home. 

To do a porosity test, take a strand of hair from each area of your head and use a flat iron on each section until it gets scorching (like smoking-hot). If there is any white residue forming in any area, then your strands are porous. It will most likely cause the stems to break more easily during color treatments, but it doesn’t mean you can’t dye over them!

The Difference Between Semi-Porous, Non-Porous, and Fully Porous Hair

Knowing which category your hair falls into will help you choose the correct coloring method and ensure you get great, long-lasting results. 

  • Semi-porous hair is able to accept color but not lighten; it is perfect for medium brunettes who want a daring hue like magenta or violet. 
  • Non-porous hair is resistant to dyes and lighteners. If you’re blonde or naturally redheaded, your hair is most likely non-porous. 
  • Fully porous hair can be colored or lightened, which makes it much easier to work with if you’re going bolder than auburn. If you dye your locks regularly, ask your stylist what kind of texture they fall into.

Before You Start Coloring Porous Hair

When picking out the hair dye, make sure you opt for a semi-permanent dye; it will provide a deeper color that lasts up to six weeks. Ensure it doesn’t contain ammonia or peroxide (these can damage porous hair and fade quickly). Most importantly, check out reviews and steer clear of products with harsh reviews (you don’t want your investment in a good cut or color ruined by something as silly as a dud hair dye). 

Remember: There are no hard and fast rules when it comes to how often you should be coloring your hair. It depends on how quickly your roots grow in and your scalp health.

The Right Products For Coloring Porous Hair

Choosing the right product for coloring porous hair can be overwhelming, especially if you’re not up on all of the latest terminology and product developments. To simplify things, talk with your stylist about what’s essential for you: whether it’s a hair color that lasts between appointments or one that is permanent after just one application. Likewise, if you want vibrant hues that match your mood, ask about trendy color services like balayage or dip-dye. Your stylist will guide you in selecting a color and product combination best suited for your needs.

Steps How To Dye Your Hair

Since porous hair is more sensitive, you will have to be extra careful while dyeing it. 

  1. The first step in dying porous hair is selecting a color and type of dye. You can go for either a semi-permanent or permanent dye, but if you are using permanent dye, you must ensure that your hair is chemically processed beforehand. 
  2. After selecting a suitable dye, wash your hair thoroughly before applying any product. 
  3. Conditioner can come in handy at this point as it would help treat your damaged strands and help when rinsing out excess color from them. 
  4. Use baby oil or petroleum jelly on the palms and rub gently so that there won’t be any coloring on the hands, which would result in unnecessary staining. 
  5. Apply the dye evenly with a comb or brush and leave it on for an hour. 
  6. Rinse off with cold water after one hour. 
  7. Repeat the process twice a week until you get desired results. 

This process might take up to two months, depending upon how much damage has been done to your hair by chemical treatments, heat styling tools, etc.

Tips for Keeping The Color In After Washing It

These are a few ways to keep the color after you wash it.

How to Dye Porous Hair
  • To maintain your dyed, colored hair, always use sulfate-free shampoo and conditioner since they are gentle enough for porous hair and do not cause any damage even after repeated use. 
  • Avoid frequently shampooing since frequent washing causes dryness, making colored hair fade away faster than usual. 
  • If you have colored-treated hair, try avoiding shampoos that contain silicone. 
  • If possible, use mild shampoos like Dove or Pantene instead of medicated ones. 
  • Avoid sun exposure, and UV rays as these lead to quicker fading of colors, especially reds and blondes. 
  • Apply sunscreen lotion whenever going out under the sun because UV rays tend to fade colors quickly. 
  • Wear protective hats and scarves during the summer season. Wear loose cotton caps during nighttime to protect hair from getting tangled up in bedsheets. 
  • Do not tie your hair too tightly as it leads to breakage of fragile strands, which may cause dyes to bleed easily. 
  • Keep yourself hydrated throughout the day because lack of water dries out the scalp, which causes flaking and itching making you scratch it and causing further damage to already fragile hair shafts resulting in increased bleeding of dyes. 
  • Do not overuse heated styling tools such as blow dryers, straighteners, etc. They tend to weaken already fragile hair shafts, making them porous easily and causing dyes to bleed through them easily.

Does Porous hair hold color?

There are two reasons porous hair doesn’t hold color as well. 

  • First, those cuticles that separate your hair into individual strands act as a series of little gates; they allow in smaller molecules so that strands can absorb, or take on, pigment molecules. The larger molecules in the dye and many different kinds of dye molecules don’t fit through those openings as easily. 
  • Second, once a portion of a strand has been exposed to specific dye molecules for an extended time, it becomes damaged because you left it in for too long. As soon as that happens, it won’t absorb new dye; instead, it pushes out any remaining color you already have in your strands. Second-day hair often looks less vibrant than freshly dyed hair: Your strands were able to absorb all of that first day’s dye, but not much more. 

It can also happen if you use dyes with higher ammonia content than what is necessary for your particular shade. Ammonia opens up cuticle cells (the same way bleach does), allowing them to accept more dye molecules, which means brighter colors, rougher-feeling strands, and a greater risk of damage from overprocessing. It’s best to avoid ammonia altogether since it dries out your scalp and may cause itching and burning sensations during application.

Frequently Asked Questions

Here are answers to some commonly asked questions about dyeing porous hair

How often should I shampoo my shampoo?

Since porous haircare needs particular attention, frequent washing is required. Most stylists recommend shampooing once a day until your hair has completely soaked up the dye. It’s also important to use sulfate-free shampoos because they don’t strip away natural oils from your scalp and hair shaft as much as traditional shampoos do.

What kind of conditioner should I use?

Some stylists recommend using deep conditioning masks every few days, while others say leave-in conditioners work best since they coat each strand of hair individually. Deep conditioning masks are better used when you have time to sit under heat (like during a relaxing bath), while leave-ins can be applied after each shower while waiting for dry towel time.

Why does my hair get greasy?

There are several reasons why your hair might get greasy after dyeing it. For example, if you’re using a permanent dye, you might notice that your scalp is getting oily because of buildup from the old color.

How do I know if my hair is porous?

Porous hair will often feel like straw or cotton candy when dry instead of smooth and silky. It will also tend to be very thick and heavy. If your hair feels like straw or cotton candy when dry, it is likely porous.

Why should I care if my hair is porous?

Many people don’t realize that porous hair can cause problems when dying it. Because porous hair absorbs color so quickly, applying color can be difficult and even dangerous if you don’t use dye products designed explicitly for porous hair.

What products should I use on my porous hair?

To ensure your color looks great and lasts longer than usual, we recommend using a semi-permanent colorant on your porous hair. Semi-permanent dyes penetrate each strand more slowly than permanent dyes but still provide excellent coverage while being gentler on strands than permanent colors can be.

Final Thoughts

If you’re trying to dye your hair, you have porous hair. If you’re not sure whether or not your hair is porous, there are a few tell-tale signs: Your hair gets oily easily and quickly; It feels like straw when wet; It tangles easily. If any of these statements apply to you, it might be time for a new hairstyle! 

Dying porous hair can be tricky; many people don’t even attempt it, but it doesn’t have to be. The key is taking care of your locks before you dye them by getting rid of as much oil as possible and using products that will protect against damage from chemical dyes.
