Why Does My Hair Turn Red When I Dye It Brown?

Hair coloring has been in vogue for centuries, with the number of people dyeing their hair only increasing with time. While dyeing hair brings about numerous possibilities in terms of colors, expectations of certain shades may not always turn out how one anticipated. This is particularly true when one tries to dye their hair brown and finds it turning reddish. This occurrence is not uncommon and has led many individuals to wonder, “Why does my hair turn red when I dye it brown?”

Several factors can play a role in determining the outcome of hair dyeing. The extent to which one’s natural hair color has absorbed the dye, the underlying pigments, and the quality of the dye are just a few of these factors. Understanding these factors with relation to the red tint after dyeing hair brown is critical to avoid such an outcome in the future. In this article, we explore why hair may turn red instead of brown and provide information on how to avoid this in the future.

Quick Summary
When hair is dyed brown, it is often necessary to first lighten the original hair color. This is usually done using bleach or another type of lightener, which strips away natural pigments in the hair. When the brown dye is then applied, it can sometimes interact with these remaining pigments in unexpected ways, resulting in red tones appearing in the final color. This can be especially noticeable in individuals with naturally warm or red undertones in their hair.

Understanding Hair Pigmentation

Understanding Hair Pigmentation

Hair pigmentation is the natural color of the hair that is determined by the amount and type of melanin present in it. Melanin is a pigment that is produced by melanocytes, a type of skin cell located in the hair follicles. It is responsible for the color of our hair, skin, and eyes. There are two types of melanin- eumelanin, which is responsible for brown and black hair color, and pheomelanin, which gives red and blonde hair color.

The amount and distribution of these pigments are determined genetically, but they can also be influenced by environmental factors such as sun exposure, hormonal changes, and aging. When hair is dyed, the natural pigments are removed or lightened by the process of bleaching, and the new color is deposited on the hair shaft. The choice of hair dye color depends on the desired outcome, but it is important to note that different hair types and textures can react differently to the dye.

The Science of Hair Dyeing

The science behind hair dyeing is quite complex. Hair dye consists of a combination of chemicals that work together to penetrate the hair shaft and deposit color molecules. The two main components of hair dye are ammonia and hydrogen peroxide. Ammonia is used to open up the hair cuticle, which allows the dye to penetrate the hair shaft. Hydrogen peroxide is then used to bleach the natural hair color, allowing the new color to be deposited.

The actual color molecule in hair dye is called a chromophore. Chromophores are molecules that absorb visible light and give objects their distinct colors. Different colors in hair dye are created by varying the types and amounts of chromophores used. For example, red dye contains chromophores that absorb green light, which gives the hair a red appearance. Understanding the science behind hair dyeing is important for achieving the desired hair color and avoiding any surprises, such as hair turning red when dyeing it brown.

Factors Contributing to Reddish Tones

Factors Contributing to Reddish Tones

There are several factors that contribute to reddish tones in hair, even after attempting to dye it brown. One factor is the natural underlying pigment of the hair. Darker hair usually contains more red and orange tones, which can show through even after dyeing.

Another factor is the type of dye used. Some dyes have a higher concentration of red pigments, leading to unintended reddish tones. This can also occur if the dye is left on for too long or if the hair is porous and absorbs too much pigment. Additionally, previous hair treatments, such as bleaching or highlighting, can change the hair’s structure and affect how it reacts to dye, contributing to reddish tones. Understanding these factors can help in selecting the appropriate dye and achieving the desired hair color.

Chemical Reactions That Cause Hair Color Change

When hair is dyed, it undergoes a chemical reaction that changes its color. The main chemicals responsible for this change are hydrogen peroxide and ammonia. These chemicals work together to break down the natural color of the hair and replace it with the desired color. Peroxide opens up the hair cuticle, allowing the dye to penetrate the hair shaft, while ammonia helps to lift the existing hair color and make it more receptive to the dye.

During the chemical reaction, the dye molecules interact with the hair’s natural pigments, causing them to change color. Depending on the type of dye used, the chemical reaction can produce a range of colors, including red, brown, blonde, and black. However, if the hair is already naturally red or has undergone previous color treatments, the chemical reaction can sometimes result in unexpected outcomes, such as reddish tones appearing in brown hair. Therefore, it is important to understand how hair dye works and to properly prepare and apply it to achieve the desired results.

Tips for Achieving Desired Hair Color

When it comes to achieving the desired hair color, there are some tips you can follow. First and foremost, it is recommended to consult with a professional hairdresser who can guide you on the best shade and type of hair dye for your hair type and condition. It is also important to perform a strand test before fully dyeing your hair to avoid any unpleasant surprises.

If you are looking for a more natural alternative to hair dye, you can try using henna or other herbal hair dyes. These natural options can be less harsh on your hair than chemical dyes and can also add shine and volume to your hair. Finally, it is important to maintain your hair color by using color-safe shampoos and conditioners and avoiding excessive heat styling and exposure to sunlight. With these tips, you can achieve the hair color of your dreams without damaging your hair.

Common Mistakes to Avoid

Common Mistakes to avoid while dyeing your hair from red to brown are plenty. Planning and preparation is essential to achieving the desired look. Factors like the starting color of your hair, the type of dye used, and your hair’s health all play a significant role in determining the final outcome. To achieve the best results, it’s essential to avoid common mistakes such as not using the right shade of brown dye, using expired hair dye, not leaving the dye on long enough, or using bleach improperly.

Using low-quality dyes can also cause hair damage and result in the wrong color. It is also essential to remember that hair dyeing is a chemical process, so it is necessary to take proper precautions and use protective gloves and clothing. Some people may be allergic to hair dyes, which can cause rashes, itchiness, or even blisters, so performing a patch test beforehand is recommended. Taking these necessary precautions and avoiding common mistakes can lead to a successful transition from red to brown hair.

Accepting and Embracing Your New Hair Color

After going through the hair dyeing process, some people might find that the resulting color is not exactly what they expected. It can be disappointing to realize that the brown hair dye has turned their hair a reddish hue. However, it’s important to remember that hair color is not a one-size-fits-all solution. Instead of feeling self-conscious or unsure about the new hue, try to embrace and love your new hair color.

If your hair has turned red after dyeing it brown, make the most of it by incorporating it into your personal style. Certain makeup shades or clothing colors might complement your new hair color beautifully. You can also experiment with different hairstyles and cuts that show off your hair’s unique shade. By accepting and embracing your new hair color, you may even discover that it unlocks a new level of confidence and self-expression.

Final Thoughts

In conclusion, the reason why hair can turn red when dyed brown isn’t a straightforward answer. It can often depend on the undertone of the original hair color, the brand and dye used, and the length of time the dye is left on. However, with the right preparation, incorporating a green or ash-based toner, or even seeking professional help, it’s possible to prevent or correct this unwanted outcome.

Ultimately, dyeing hair is a personal choice, and understanding the potential risks and rewards beforehand is important. While turning red when dyeing brown may come as a surprise, it’s a common occurrence, and with some extra effort and preparation, it’s possible to achieve the desired hair color without any unwanted surprises.
