Have you ever noticed darker pigmentation on your forehead compared to the rest of your face? If yes, then you might be wondering why it happens and how to treat it. In this article, Dr. Nivedita Dadu, a dermatologist explains the reasons for forehead pigmentation and various treatments available in dermatology to get rid of it.

Reasons/Causes of Pigmentation on Forehead

Forehead pigmentation can be a bothersome issue. The most common reason for forehead pigmentation is the use of hair dyes or hair colours containing ingredients like indigo that can darken the forehead and eventually spread to other parts of the face. 

“While many people opt for organic and chemical-free hair dyes, it's important to note that even high-quality hair dyes in India often contain indigo,” says Dr. Nivedita. According to her, Indigo, a vegetable-based hair colour, can gradually pigment the skin, resulting in significant pigmentation issues. 

“It is crucial to carefully scrutinise the ingredients of your chosen hair dye including those marketed as vegetable hair colours and steer clear of products containing indigo and PPD,” advises Dr. Nivedita.

Acanthosis is another common reason for skin pigmentation on the forehead that can result in purple, grey, brown, and dark pigmentation on the skin, accompanied by alterations in its texture. This condition can also impact other areas of the body, including the neck, underarms, and thighs. Acanthosis is typically linked to factors such as a sedentary lifestyle, elevated insulin levels, or metabolic disorders like thyroid problems, high cholesterol, or blood sugar imbalances.

The application of hair oils is another factor contributing to forehead pigmentation, especially when using oils like mustard or amla oil. Dermatologists generally advise against hair oiling; however, if you still prefer to do so, it is recommended to opt for lighter oils such as coconut or olive oil. Dr. Nivedita suggests avoiding overnight oiling and refrain from using mustard and amla oil, as they can exacerbate pigmentation. Also apply the oil approximately 30 minutes before washing your hair to minimise the chances of pigmentation.

Excessive sun exposure and the friction resulting from wearing helmets are additional factors that contribute to forehead pigmentation. Prolonged exposure to the sun's rays and constant rubbing or pressure from helmets can alter the skin's tone and texture, leading to an increase in thickness and darkening of the affected area.

Prevention tips for forehead pigmentation

Lifestyle changes

Making lifestyle changes is crucial for addressing forehead pigmentation. Start by minimising the use of hair dyes and colours, opting instead for vegetable-based, organic alternatives that are free of indigo and PPD. It's also advisable to avoid black mehndi. Regularly apply sunscreen, taking into account your skin type and sun exposure. Additionally, incorporate antioxidants like vitamin C, glutathione, and vitamin B12 into your diet. Glutathione, renowned for its effectiveness in combating pigmentation, can be consumed as a supplement for a minimum of three months per year, especially if you struggle with pigmentation issues.

Nourishing your skin with a healthy diet that includes a variety of colourful fruits and vegetables rich in antioxidants can work wonders for your skin. These nutrient-packed foods contribute to a radiant and luminous complexion, enhancing the brightness and natural glow of your skin.

Changes in skin routine

To address pigmentation concerns, incorporate skin-lightening creams into your nighttime skincare routine alongside your daytime sunscreen application. However, it is important to choose safe and effective skin-lightening creams that are free from steroids and hydroquinone. Look for creams that contain ingredients such as glycolic acid, kojic acid, arbutin, and licorice, as they can effectively reduce pigmentation while enhancing the overall tone, texture, and quality of your skin.

If your current skincare routine fails to yield desired results, Dr. Nivedita suggests considering additional treatments to address your pigmentation concerns. According to her, it is advisable to consult an experienced and reliable dermatologist for guidance. They will suggest specialised treatments like POWER EXPO, MAGIC BLEND, and DIAGENESIS, which employ a distinctive blend of q-switch laser and chemical peels. According to Dr. Nivedita these treatments offer distinct advantages over standard chemical peels and can provide effective solutions for your specific needs.

Conclusion

Forehead pigmentation, a potential source of worry, can be attributed to multiple factors. Nevertheless, there exist numerous preventive measures, such as modifying one's diet, lifestyle, and skincare routine, that can aid in reducing this unappealing skin condition. Seeking guidance from a dermatologist is also advisable, as they can provide specialised treatments to effectively diminish forehead pigmentation.
