Why is my hair turning red?
Hair turning red naturally can be due to several factors. Sun exposure, hard water build-up, diet, and even certain deficiencies such as Vitamin B12 could be responsible for this color shift. Age, genetics, medications, stress, and diet can also induce changes in hair color, potentially leading to a red hue (source, source).

Common Causes of Red Tones in Natural Hair
Red tones in natural hair are a common occurrence, and they can arise from various factors related to genetics, hair care, and environmental influences. Understanding these causes can help in managing or controlling the appearance of red undertones in hair.
1. Genetics
One of the primary reasons for red tones in hair is genetics. Hair color is determined by the type and amount of melanin in the hair follicles. Eumelanin creates brown or black hair, while pheomelanin gives hair its red, orange, or yellow hues.
People with a higher proportion of pheomelanin may naturally have red undertones, especially in lighter or blondish hair colors. Even individuals with dark brown or black hair may notice subtle red hues under the right lighting.
2. Sun Exposure
Prolonged exposure to the sun can naturally lighten hair and bring out red tones. Ultraviolet (UV) rays can break down melanin and enhance the presence of pheomelanin, causing red undertones to become more prominent.
This is especially noticeable in people with naturally dark hair who may notice their hair turning reddish or coppery after spending extended time outdoors.
3. Hair Dye and Chemical Treatments
Hair dyeing is another significant cause of red tones, especially in brown or blonde hair. Warm-toned dyes, such as copper, gold, and auburn, may leave a red or orange tint on the hair. Overuse of bleach can also strip the hair of its natural pigment, making underlying red or orange tones more visible.
Oxidation of hair color over time can reveal red undertones that were not apparent immediately after coloring.
4. Heat Styling
Excessive use of heat styling tools like straighteners, curling irons, or blow dryers can alter the hair’s pigment composition. The heat can open the hair cuticle, leading to a loss of natural color molecules and causing the red pigments within the hair shaft to become more exposed.
This is particularly noticeable in people with naturally dark hair, where the heat often brings out brassy red tones.
5. Hard Water
Hard water, which contains high levels of minerals like calcium and magnesium, can affect the color of your hair. Over time, mineral buildup can alter the hair’s pH balance, causing hair to take on red or orange hues.
This effect is often noticeable in those with blonde or light brown hair, as the minerals can react with the hair’s natural pigments, leading to an undesired warm or reddish tint.
6. Underlying Hair Health Issues
Certain hair health issues, such as nutrient deficiencies, can contribute to changes in hair color, including the emergence of red tones. Vitamin B12, copper, and iron deficiencies, for instance, can alter how melanin is produced in the hair follicles, sometimes enhancing the red undertones in the hair. In these cases, correcting nutritional imbalances may help restore a more natural hair color.
7. Seasonal Changes
Changes in seasonal weather can also influence the visibility of red tones in hair. During colder months, hair may become drier and more porous, making it more susceptible to absorbing red pigments from environmental factors. The humidity in the air during warmer months can bring out coppery and reddish undertones.
Managing Red Tones in Hair
To control or adjust red tones in hair, try these effective strategies:
- Use Purple or Blue Shampoos: These neutralize brassiness in blonde or light brown hair, and blue shampoos are perfect for reducing red undertones in darker hair.
- Color-Correcting Products: Green conditioners can counteract red tones, especially for brown or blonde hair, leaving it with a more neutral shade.
- Limit Sun Exposure: Protect your hair from UV rays by wearing hats or using UV-protectant sprays to prevent red tones from intensifying.
- Choose Cool-Toned Dyes: Opt for ash or cool shades to neutralize warm, red undertones when dyeing your hair.
- Reduce Heat Styling: Minimize the use of heat tools to prevent red tones from becoming more noticeable.
- Maintain Hair Health: Regular conditioning keeps hair smooth and hydrated, reducing the appearance of red undertones.
- Regular Touch-Ups: Keep your color balanced by scheduling frequent touch-ups to avoid fading and uneven tones.
Conclusion
Witnessing your hair turn red can be surprising, but understanding the potential causes can help you manage this change. Whether it's tweaking your hair care routine, adjusting your diet, or using color-correcting hair products, you can take control of your hair's color. Remember, always consult a professional if you're unsure about the cause or if the red hue persists despite your efforts.
