What Happens If You Keep Purple Shampoo In For Too Long? Your Hair SOS Guide

Purple shampoo, the holy grail for blondes, silvers, and highlighted hair. It’s designed to neutralize brassy yellow tones, leaving your hair looking bright, vibrant, and salon-fresh. But like any powerful tool, misusing it can lead to unintended consequences. Leaving purple shampoo in for too long is a common mistake, and understanding the potential pitfalls is crucial for maintaining healthy, beautiful hair. So, what exactly happens when you overdo it with the purple? Let’s dive deep into the purple peril.

The Science Behind Purple Shampoo

Before we explore the potential downsides, let’s quickly recap how purple shampoo actually works. The color wheel tells us that purple is directly opposite yellow. This means that purple pigments can effectively counteract and neutralize unwanted yellow or brassy tones in light-colored hair.

The purple pigments in the shampoo deposit onto the hair shaft, counteracting the yellow and creating a cooler, brighter tone. This is a temporary fix, as the pigments wash away with each shampoo.

The strength of the purple pigment, the porosity of your hair, and the length of time the shampoo sits on your hair all play a role in the final result.

The Potential Consequences of Overdoing It

Leaving purple shampoo on for too long can have a range of effects, from subtle changes to more dramatic alterations in your hair color. Here’s a breakdown of the most common consequences:

The dreaded purple tint

This is the most common and often the most feared consequence. When purple shampoo sits on your hair for an extended period, the purple pigments have more time to deposit. This can lead to an unwanted purple or lavender tint, particularly on porous or light blonde hair. The result can range from a subtle lilac hue to a more noticeable and unflattering purple cast.

Dryness and damage

Many purple shampoos, while effective at toning, can be drying. This is because they often contain sulfates and other ingredients that strip the hair of its natural oils. Leaving the shampoo on for too long exacerbates this effect, potentially leading to dry, brittle, and damaged hair. Over time, this can result in breakage, split ends, and a dull appearance.

Uneven toning

If your hair has varying levels of porosity (meaning some sections absorb more moisture than others), leaving purple shampoo on for too long can result in uneven toning. For example, highlighted areas, which are typically more porous, might grab more of the purple pigment, resulting in patchy or streaky color.

Dulling of highlights

While purple shampoo is designed to brighten blonde and highlighted hair, overusing it can have the opposite effect. Excessive purple pigment can actually dull the overall appearance of your highlights, making them look less vibrant and dimensional. Instead of bright, shimmering highlights, you might end up with muted, ashy tones.

Scalp irritation

Although less common, leaving purple shampoo on your scalp for an extended period can sometimes cause irritation, especially if you have sensitive skin. The harsh ingredients in some formulas can disrupt the scalp’s natural balance, leading to dryness, itching, and even redness.

Factors Influencing the Outcome

The extent to which leaving purple shampoo on for too long affects your hair depends on several key factors:

Hair Porosity

High porosity hair absorbs moisture quickly but also loses it just as rapidly. This type of hair tends to grab onto purple pigment more readily, making it more susceptible to over-toning.

Low porosity hair has a tightly closed cuticle layer, making it more resistant to absorbing moisture and pigment. However, with prolonged exposure, even low porosity hair can be affected by purple shampoo.

Medium porosity hair is considered the ideal, as it absorbs and retains moisture well. However, even medium porosity hair can be over-toned if purple shampoo is left on for too long.

Hair Color and Tone

The lighter your hair, the more susceptible it is to being affected by purple shampoo. Very light blonde or platinum blonde hair will show purple tones much more readily than darker blonde shades. Similarly, hair that already has cool tones will be more likely to turn purple compared to hair with warmer undertones.

The Specific Shampoo Formula

The potency of the purple pigment varies significantly between different brands and formulas. Some purple shampoos are designed to be more intense, while others are more gentle. Always read the instructions carefully and start with a shorter processing time, especially if you’re trying a new product.

Application Technique

How you apply the purple shampoo can also influence the results. Applying it evenly throughout your hair is crucial to avoid patchy toning. Pay particular attention to areas that tend to get brassy, such as the roots and around the face. Using too much product can also increase the risk of over-toning.

How to Fix Over-Toned Hair

So, you’ve accidentally left the purple shampoo on for too long and now you’re sporting a slight lavender hue? Don’t panic! Here are a few remedies to try:

Clarifying Shampoo

A clarifying shampoo is your first line of defense. These shampoos are designed to remove buildup and impurities from the hair, including excess purple pigment. Use a clarifying shampoo to wash your hair thoroughly, focusing on the areas that are most affected. You may need to repeat this process a few times to see a noticeable difference. Be sure to follow with a moisturizing conditioner to replenish any lost moisture.

Anti-Dandruff Shampoo

Believe it or not, anti-dandruff shampoo can also help to fade purple tones. These shampoos often contain sulfates, which can strip the hair of pigment. Use an anti-dandruff shampoo to wash your hair, focusing on the purple areas. Again, be sure to follow with a moisturizing conditioner.

Baking Soda Paste

Baking soda is a natural cleanser that can help to lift color from the hair. Mix baking soda with water to create a paste and apply it to the affected areas. Let it sit for a few minutes, then rinse thoroughly. This method can be drying, so be sure to follow with a deep conditioner.

Vitamin C Mask

Crush vitamin C tablets and mix them with water to create a paste. Apply the paste to your hair and leave it on for 20-30 minutes. Vitamin C is a mild bleaching agent that can help to fade the purple tones. Rinse thoroughly and follow with a moisturizing conditioner.

Professional Color Correction

If none of these home remedies work, or if the purple tint is severe, it’s best to consult a professional hairstylist. A color correction specialist can assess the damage and use professional techniques to neutralize the purple tones without further damaging your hair. This might involve using a color remover or applying a toner to counteract the purple.

Prevention is Key: Using Purple Shampoo Correctly

The best way to avoid over-toning your hair is to use purple shampoo correctly from the start. Here are some tips for safe and effective use:

Read the Instructions

This might seem obvious, but it’s crucial to read the instructions on your specific purple shampoo. Different formulas have different recommended processing times. Adhere to the manufacturer’s guidelines for the best results.

Start with a Short Processing Time

If you’re using a new purple shampoo, start with a shorter processing time than recommended. For example, if the instructions say to leave it on for 3-5 minutes, start with 1-2 minutes. You can always increase the time on your next wash if needed.

Dilute the Shampoo

To lessen the intensity, consider diluting the purple shampoo with your regular shampoo. This will help to distribute the pigment more evenly and prevent over-toning.

Apply Evenly

Use gloves to apply the purple shampoo evenly throughout your hair, focusing on the areas that tend to get brassy. Avoid applying it directly to your scalp, as this can cause irritation.

Monitor Your Hair

Keep a close eye on your hair while the purple shampoo is processing. If you start to notice any purple tones developing too quickly, rinse it out immediately.

Use Sparingly

Purple shampoo is not meant to be used every day. Overusing it can lead to dryness, damage, and unwanted purple tones. Use it once or twice a week, or as needed to maintain your desired tone.

Deep Condition Regularly

Because purple shampoo can be drying, it’s essential to deep condition your hair regularly to replenish moisture. Use a hydrating hair mask or leave-in conditioner to keep your hair healthy and strong.

Consider a Purple Conditioner or Mask

For a more gentle toning effect, consider using a purple conditioner or mask instead of shampoo. These products typically have a lower concentration of purple pigment and are less likely to cause over-toning.

When to See a Professional

While home remedies can be effective for mild over-toning, there are times when it’s best to seek professional help. If you experience any of the following, consult a hairstylist:

  • Severe purple tint that doesn’t fade with home remedies
  • Significant hair damage or breakage
  • Scalp irritation or allergic reaction

A professional hairstylist can assess your hair and scalp and recommend the best course of treatment to restore your hair’s health and color. They can also provide guidance on how to use purple shampoo safely and effectively in the future.

In conclusion, while purple shampoo is a fantastic tool for maintaining bright, beautiful blonde and silver hair, it’s essential to use it correctly. Leaving it on for too long can lead to unwanted purple tones, dryness, and damage. By understanding the potential consequences and following the tips outlined in this article, you can enjoy the benefits of purple shampoo without the purple peril. Remember, prevention is key, and when in doubt, always consult a professional.

What are the immediate signs that I’ve left purple shampoo in for too long?

If you’ve overdone it with the purple shampoo, the most noticeable sign is a lavender or purple cast to your hair, particularly on lighter sections like highlights or blonde areas. You might also observe a dullness or darkening of your hair, as the purple pigment can build up and counteract the desired brightening effect.

Beyond the color change, your hair might feel drier and more brittle than usual. This is because extended exposure to the shampoo’s ingredients, even though designed for cleansing, can strip away natural oils, leading to a less healthy and manageable texture. It’s crucial to act quickly if you notice these signs to prevent further damage.

How long is considered “too long” for leaving purple shampoo in?

Generally, most purple shampoo instructions recommend leaving the product in for 2-5 minutes. Anything beyond this timeframe increases the risk of over-toning, leading to unwanted purple hues. The exact “too long” duration varies depending on your hair’s porosity and the shampoo’s pigment strength.

Extremely porous hair absorbs pigment much faster than hair with low porosity, making it more susceptible to turning purple quickly. Therefore, individuals with highly porous hair should start with a shorter processing time, perhaps even less than 2 minutes, and carefully monitor the results. If your shampoo is highly pigmented, err on the side of caution and stick to the lower end of the recommended timeframe.

Can leaving purple shampoo in too long permanently damage my hair?

While leaving purple shampoo in too long won’t typically cause permanent structural damage to your hair in the same way that bleaching would, it can definitely lead to temporary dryness and brittleness. The strong pigments and cleansing agents, when left on for an extended period, can strip your hair of its natural oils and moisture, making it more prone to breakage.

The resulting dryness and discoloration may take several washes to correct. In severe cases of over-toning, the hair can appear dull and lifeless, requiring deep conditioning treatments and potentially professional color correction to restore its health and vibrancy. Therefore, it’s important to exercise caution and follow the instructions carefully.

What’s the best way to remove the purple tint if I overdid it with purple shampoo?

The most immediate solution is to wash your hair with a clarifying shampoo. These shampoos are designed to deeply cleanse and remove buildup, which will help strip away the excess purple pigment. You might need to repeat this process several times, but be gentle and avoid over-washing, which can further dry out your hair.

Another effective method is to use a warm olive oil or coconut oil mask. Apply the oil generously to your hair, focusing on the areas with the strongest purple tint, and leave it on for at least 30 minutes before shampooing and conditioning as usual. The oil helps to lift the pigment and restore moisture to your hair, making it a gentler alternative to harsh clarifying shampoos.

How can I prevent over-toning with purple shampoo in the future?

The key to preventing future over-toning is to start conservatively and gradually increase the processing time as needed. Begin by leaving the purple shampoo in for the shortest recommended time (e.g., 1-2 minutes) and assess the results. If your hair isn’t toned enough, you can slightly increase the time in subsequent washes.

Another helpful tip is to dilute the purple shampoo with your regular shampoo. This reduces the concentration of the purple pigment, making it less likely to over-tone your hair. Also, closely observe your hair’s color while the shampoo is in. If you notice it starting to turn too purple, rinse immediately.

Are there alternative products to purple shampoo that are less risky?

Yes, there are several alternative products that can help maintain blonde or highlighted hair without the risk of over-toning. Purple conditioners and masks often contain less pigment than shampoos, providing a more subtle toning effect. These products are gentler and can be used more frequently without causing dramatic color changes.

Another option is to use a blue shampoo or conditioner, which is specifically designed to neutralize orange tones in brunette hair. Blue shampoos tend to be less potent than purple shampoos, making them a safer choice for those who are prone to over-toning. You can also explore color-depositing conditioners in shades like pearl or silver, which can add subtle brightness and shine without a strong purple hue.

When should I seek professional help for hair that has been over-toned by purple shampoo?

If you’ve tried the at-home remedies, like clarifying shampoos and oil masks, and the purple tint persists, it’s time to seek professional help. A colorist can assess the extent of the over-toning and determine the best course of action to correct the color without further damaging your hair.

In cases of severe over-toning, a professional may use a color remover or light bleach wash to gently lift the excess purple pigment. They can also formulate a custom toner to neutralize any remaining unwanted tones and restore your hair to its desired shade. Trusting a professional will ensure the process is done safely and effectively.
