Does Toner Damage Hair?

Research has shown that toner, if used correctly following the instructions, is unlikely to damage hair. However, overexposure, frequent use, or applying it to already damaged hair can result in potential harm.

Damage from toner is not a major concern for hair health. Surprisingly, it can even have positive effects at times. Let’s take a closer look:

Purpose of Toner: Hair toner is used to neutralize any unwanted brassiness or orange tones, especially in lightened or bleached hair. This product has the ability to improve and perfect the overall hair color.
Minimal Penetration: Toner molecules, being larger in size, do not reach deep into the hair shaft as permanent dyes do. As a result, the potential damage to the inner structure of the hair is reduced.
Potential for Dryness: Nevertheless, certain toners containing ammonia, especially those that are permanent, have the ability to slightly raise the outer layer of the hair cuticle (known as the cuticle) in order to add color. This may cause the hair to feel slightly drier or more fragile.

When coloring deposit-only strands, it is important to always think about the toner. This will help maintain the health of the hair follicles and ensure that the cuticle stays strong and undamaged.

What is a Hair Toner?

Toner is a gentler alternative to traditional hair dye, as it does not contain high levels of ammonia. Unlike regular hair dyes that rely on ammonia to raise the hair’s pH level and deposit color within the hair shaft, toner simply coats the outer layer of the hair fibre without penetrating deeply. This product enhances hair color temporarily without any permanent changes. The outcome is that it does not entirely change the color of your hair; rather, it simply adjusts or enhances its current hue.

Toners are typically used after bleaching or regular dyeing to balance out unwanted brassiness and blend warm tones. Timing is flexible when it comes to toning your hair. It’s recommended to wait for a few days or even weeks to achieve the best results based on your hair type and desired look.

In the past, temporary toner was only available as a dye, but nowadays it can be found in various other forms, including:

Shampoo
Conditioner
Hair mask
Hair gloss
Hair foam

Changing your hair color at home is more convenient with this method, reducing the need to always seek help from a professional. But for a more permanent color change, it is recommended to trust a professional hair dresser with your locks.

How Does Toner Damage Your Hair?

When used properly, toner does not harm the hair. But, if applied incorrectly or misused, toner has the potential to cause damage to your hair. Here are some potential negative effects of using toner on your hair:

1. Over Processing

It is important to consider both the timing and strength of the toner when applying for the best results. Over-processing from extended toner exposure or using a too potent toner can lead to dry, brittle hair that is prone to breakage. Following the instructions on the toner and not exceeding the recommended processing time is important to prevent damage.

2. Improperly Formulated Toners

It is important to be cautious when selecting a toner for your hair, as certain products may have harmful chemicals that can cause damage. Stick to trusted brands and carefully review the ingredients to avoid substances like ammonia or high levels of alcohol. These components can damage your hair by removing its natural moisture, leading to dry and weak strands that are more likely to break. Search for carefully crafted toners that can reduce the chances of hair damage and keep your hair healthy.

3. Wrong Color Section

Choosing the wrong toner shade for your hair could result in unpleasing results. Choosing a toner that doesn’t match your hair tone can result in a patchy or artificial look.

4. Incorrect Application

Misusing toner on your hair can cause harm. Damage may happen if the toner is not spread evenly or used too often. Inconsistent color outcomes may arise from uneven distribution of the toner, and excessive use can make the hair dry and fragile.

3 Signs of Hair Damage From Toner

There are several signs that indicate your hair has been damaged by toner.

These are the usual signs to be aware of:

1. Dryness and Brittleness

Toner can lead to hair damage by causing dryness and brittleness in the hair strands. Applying it incorrectly or leaving it on for an extended time can remove the natural moisture in the hair, resulting in dryness. This dryness can give the hair a rough texture and a dull, lifeless appearance. Furthermore, damaged hair from toner may become fragile, increasing the likelihood of breakage and split ends.

2. Color Fading or Unevenness

Toner can cause damage to hair by causing color to fade or become uneven. When toner is not applied correctly or if the hair is damaged from processing, the color may fade rapidly or appear splotchy and inconsistent. As a result, the desired tone achieved with toner application may not be long-lasting or evenly spread throughout the hair. You might observe sections where the shade is not consistent, causing an irregular look.

3. Scalp Irritation

Toner can cause hair damage that may lead to hair loss if not applied or rinsed properly, leading to scalp irritation. Symptoms like itchiness, redness, and sensitivity may be experienced, along with tightness or discomfort in the scalp. Flaky skin or dandruff-like flakes may appear due to the toner’s ingredients or an allergic reaction, leading to scalp irritation. In case hair loss is caused by toner irritation, discontinue use and consult a hairstylist or dermatologist for help.

Is toner less damaging than hair dye?

Toner is proven to be a much gentler option for hair compared to permanent dye. It does not harm the structure of the hair fiber, instead, it simply covers the exterior of each strand.

Using bleach and hair dye can be damaging as they often contain high levels of hydrogen peroxide and sometimes ammonia. Overusing these products can result in negative effects on both your hair and scalp, including potential hair loss in the long run.

When refreshing your hair color, toner is recommended over dye or bleach, according to experts. Toning can help boost your hair color in a more gentle way compared to regular dyeing, minimizing potential damage.

How Does Hair Toner Work?

Hair toner works by depositing pigment onto the hair shaft to neutralize unwanted tones and enhance the overall hair color.

Balancing Act: Hair color is made up of underlying pigments, melanin (contributing to brown and black shades) and pheomelanin (contributing to red tones), and artificial color deposits from dyes. Toner targets these pigments to achieve a desired outcome.
Neutralizing Unwanted Tones: Bleaching or lightening hair can sometimes leave behind brassy or orange tones,especially in light blonde or highlighted hair. Toner uses pigments of the opposite color on the color wheel to neutralize these unwanted tones. For example, purple toner counteracts brassy yellow tones, and blue toner can counteract orange tones.
Subtle Color Shift: Toner can also be used to create a subtle color shift within a desired color range. For example,a gold toner can add warmth to blonde hair, while an ash toner can add coolness.
Limited Penetration: Unlike permanent hair dye, toner molecules are relatively large and don’t penetrate deep into the hair shaft. They primarily deposit color on the hair’s cuticle (outer layer). This minimizes potential damage to the hair’s inner structure.
PH plays a role: Toner can be acidic or alkaline depending on its purpose. Acidic toners help close the hair cuticle and deposit cooler tones. Alkaline toners can slightly open the hair cuticle to deposit warmer tones or correct stubborn brassiness.
