Hair dye is a wonderful way to transform our appearance and express our individuality. However, maintaining the vibrancy of hair dye can be a challenge. There are various factors that can cause hair dye to fade, and one product that has raised questions among many is Selsun Blue. People often wonder if using Selsun Blue will have an impact on their carefully colored hair. Does it cause hair dye to fade? To understand this, we need to explore the nature of Selsun Blue, the science behind hair dye, and how they might interact within the complex environment of our hair.
Understanding Selsun Blue
Composition of Selsun Blue
Active Ingredients: Selsun Blue contains selenium sulfide as one of its main active ingredients. This compound is known for its antifungal properties. It is often used to treat dandruff and other scalp conditions related to fungal overgrowth. The selenium sulfide works by reducing the growth of the fungus on the scalp, which helps to alleviate itching and flaking.
Other Components: In addition to selenium sulfide, Selsun Blue also has other ingredients such as surfactants. These surfactants help in the cleansing process, allowing the product to remove dirt, oil, and dead skin cells from the scalp. The combination of these ingredients makes Selsun Blue an effective dandruff – fighting shampoo.
How Selsun Blue Works on the Scalp
Fungal Inhibition: When applied to the scalp, the selenium sulfide in Selsun Blue targets the fungus responsible for dandruff. It disrupts the cell membranes of the fungus, inhibiting its growth. This action helps to control the overproduction of skin cells that leads to dandruff. By reducing the fungal population, the scalp environment becomes healthier.
Cleansing Action: The surfactants in Selsun Blue work to remove the debris and excess oil from the scalp. This cleansing process not only helps in getting rid of dandruff flakes but also keeps the scalp clean. A clean scalp is essential for maintaining healthy hair as it allows the hair follicles to function properly.
Understanding Hair Dye
Types of Hair Dye
Permanent Dye: Permanent hair dyes contain colorants that penetrate deep into the hair shaft, specifically the cortex.
These dyes use a combination of ammonia and peroxide. The ammonia opens the cuticle of the hair, allowing the colorants to enter, and the peroxide helps to develop the color. Once the dye has set, it forms a permanent bond within the hair structure, and the color remains until the hair grows out or is chemically treated to remove it.
Semi – Permanent Dye: Semi – permanent dyes have smaller colorant molecules that deposit on the surface of the hair shaft and slightly penetrate the cortex. They do not use ammonia or require a developer like permanent dyes. Instead, they rely on the porosity of the hair to hold the color. Semi – permanent dyes usually wash out over several shampoos, typically within 4 – 6 weeks.
Temporary Dye: Temporary dyes only coat the outside of the hair shaft. They are often made with ingredients like food coloring or other non – permanent colorants. These dyes can be easily removed with a single wash as they do not penetrate the hair structure at all.
How Hair Dye Adheres to the Hair
Cuticle Interaction: For all types of hair dye, the condition of the hair cuticle plays a crucial role. In healthy hair, the cuticle is smooth and tightly packed, acting as a protective layer. When dyeing hair, the goal is to either open the cuticle (in the case of permanent dye) or take advantage of its natural porosity (for semi – permanent and some temporary dyes). Once the dye molecules are in contact with the hair, they interact with the proteins in the cortex and cuticle to provide color.
Bonding in Permanent Dye: In permanent dye, chemical reactions occur that create new bonds within the hair structure.
The colorants react with the hair’s natural melanin and other proteins, resulting in a long – lasting color change. This bonding process is what makes permanent dye resistant to normal washing and wear.
Interaction Between Selsun Blue and Hair Dye
Potential Effects on the Cuticle
Altering the Cuticle’s Condition: The surfactants in Selsun Blue can affect the hair cuticle. While they are designed to clean the scalp, they may also interact with the cuticle layer of the hair. If the cuticle is disrupted or damaged, it can lead to changes in how the hair dye is retained. For example, if the cuticle becomes lifted or roughened, the dye molecules may be more likely to be washed away.
Impact on Hair Porosity: Selsun Blue’s action on the hair might also change its porosity. If the product causes the hair to become more porous, it can affect the way semi – permanent and temporary dyes adhere. More porous hair may absorb the dye more quickly but also lose it faster during washing. In the case of permanent dye, changes in porosity could potentially affect the stability of the dye within the hair structure.
Chemical Interactions
Selenium Sulfide and Dye Molecules: The selenium sulfide in Selsun Blue could potentially interact with the dye molecules themselves. It might cause chemical reactions that break down the dye or alter its color. For instance, if there are chemical groups in the dye that are sensitive to sulfur – containing compounds, the presence of selenium sulfide could lead to fading. However, the exact nature of these potential interactions would depend on the specific chemical composition of the hair dye.
Interaction with Dye Fixatives: In permanent dyes, there are fixatives that help in binding the color to the hair. Selsun Blue might interfere with these fixatives, weakening the bond between the dye and the hair. This could result in the dye fading more quickly than normal.
Real – World Observations and Studies
Consumer Reports
Mixed Experiences: Many consumers have reported different experiences regarding the use of Selsun Blue and hair dye.
Some have noticed that their hair dye seems to fade more quickly after using Selsun Blue regularly. For example, those with brightly colored permanent dyes like red or purple have seen a gradual loss of color intensity. However, others have not noticed a significant difference, especially if they have darker or more natural – looking hair dyes.
Variations in Hair Types: It seems that the effect of Selsun Blue on hair dye can vary depending on hair type. People with fine hair may notice more significant fading as their hair tends to be more porous and more easily affected by external products. In contrast, those with thick, coarse hair may not experience as much fading as the dye is more deeply embedded within the hair structure.
Scientific Studies (if available)
Limited Research: There is currently a lack of extensive scientific studies specifically focused on the interaction between Selsun Blue and hair dye. However, general research on the effects of shampoos with similar active ingredients on hair color can provide some insights. Studies on the impact of sulfur – containing compounds on hair dye stability could be relevant in understanding the potential effects of Selsun Blue.
Tips for Using Selsun Blue with Dyed Hair
Alternate Shampoos
Reducing Frequency: If you are concerned about Selsun Blue fading your hair dye, you can reduce the frequency of using it. Instead of using it every time you wash your hair, you can alternate between Selsun Blue and a gentle, color – safe shampoo. This way, you can still benefit from the antifungal properties of Selsun Blue while minimizing its potential impact on your hair dye.
Using a Mild Shampoo: When you do use Selsun Blue, follow it up with a mild, color – protecting shampoo. This can help to restore the hair’s natural pH and protect the cuticle. Look for shampoos that are specifically formulated for color – treated hair and contain ingredients like antioxidants and UV protectants.
Protecting the Hair During Washing
Gentle Washing: When washing your hair with Selsun Blue, be gentle. Avoid scrubbing vigorously, as this can further damage the hair cuticle and increase the likelihood of dye fading. Use your fingertips to massage the shampoo onto the scalp in a circular motion, and let the water run through the hair to rinse it out.
Rinse Thoroughly: Make sure to rinse your hair thoroughly after using Selsun Blue. Any residue left on the hair can continue to interact with the dye and potentially cause fading. Use lukewarm water for rinsing, as hot water can also be detrimental to the hair dye by opening the cuticle more than necessary.
Conclusion
