The Science Behind Permanent Hair Color Dye Shampoos: A Natural Solution to Gray Hair
May 09, 2025 | By Maria Eliza Pineda

Many people face the challenge of premature graying, an inevitable part of aging that can also be triggered by stress, pollution, or nutritional deficiencies. For many, gray hair is not just a physical change but an emotional one as well. That’s why the search for effective and long-lasting gray hair solutions is growing.
One of the most innovative developments in hair care is the use of permanent hair color dye shampoos, a convenient way to restore hair color while simply washing your hair. But how exactly do they work? And is there a more natural alternative? This is where Mayraki Anti-Gray Hair Color Restoring Treatment comes in, a plant-based solution that supports natural hair color restoration without harsh dyes or long-term damage.
Understanding Hair Pigmentation
Our natural hair color comes from melanin—a pigment produced by melanocytes in our hair follicles. There are two types of melanin that determine hair color: eumelanin (black or brown) and pheomelanin (blonde or red). The combination of these two results in our unique hair shades.
As we age, the production of melanin in the hair follicles slows down. When melanin levels decrease or disappear entirely, hair turns white or gray. Aside from aging, stress, genetics, and environmental factors can speed up the graying process.
How Permanent Hair Color Dye Shampoos Work
Ammonia: Opens the Hair Cuticle
The first step in the permanent hair dye process involves opening the hair cuticle with ammonia. The cuticle is the outer layer of the hair, and it must be opened so the dye molecules can penetrate deeply.
Hydrogen Peroxide: Removes Natural Pigment
Once the cuticle is opened, hydrogen peroxide is used to remove the hair’s natural pigment. This creates a blank canvas for the new color to be applied. This is effective in really getting good color payoff and color accuracy.
Dye Molecules: Enter the Cortex and Provide Permanent Color
After the natural pigment is stripped away, dye molecules enter the cortex, the middle layer of the hair. There, the molecules oxidize and expand, becoming large enough to get trapped inside the hair strand. This process results in permanent hair color. The color can last for several weeks or months, but as new hair grows from the roots, root touch-ups are needed to maintain an even shade throughout.
Potential Risks of Permanent Hair Dye
Allergies to Chemicals Like PPD
One of the main ingredients in many hair dyes is PPD (paraphenylenediamine). While effective at creating long-lasting color, PPD is also known to cause allergic reactions. Some users may experience itching, swelling, or in severe cases, blistering on the scalp.
Hair Damage Due to Harsh Chemicals
The combination of ammonia and peroxide can cause hair dryness and brittleness. Frequent use can strip the hair of its natural oils and moisture, leading to split ends and breakage over time.
Environmental Impact
In addition to health concerns, many dye shampoos contain chemicals that are not eco-friendly. These ingredients can be harmful to the environment when washed down the drain or disposed of improperly.
A Natural Alternative: Mayraki Anti-Gray Hair Color Restoring Treatment
A Plant-Based Formula for Natural Color Restoration
The Mayraki Anti-Gray Hair Color Restoring Treatment offers an alternative that doesn’t rely on harsh chemicals to cover gray hair. Instead, it stimulates the body’s natural ability to produce melanin, the pigment responsible for hair color.
Using plant-based ingredients, the treatment helps reactivate melanin production in the hair follicles. Over time, this gradually restores natural hair pigmentation from the root, not just on the surface.
Sulfate-Free, Paraben-Free, and Vegan-Friendly
One of the biggest advantages of Mayraki’s treatment is its gentle formula. It’s sulfate-free, paraben-free, and 100% vegan-friendly, making it safe for daily use and environmentally conscious.
Comparison: Chemical Dyes vs. Natural Treatments
When choosing a gray hair solution, it’s important to weigh the differences between traditional chemical dyes and Mayraki’s natural alternative:
Chemical Dyes provide instant results. In just one application, gray hair is coated with a new color. However, this comes at the cost of potential allergic reactions, dryness, and long-term damage.
On the other hand, Mayraki Anti-Gray Hair Color Restoring Treatment restores natural color gradually. While not instant, it’s much safer, gentler, and promotes long-term hair health.
Long-Term Benefits vs Short-Term Effects
The science of permanent hair color dye shampoos relies on strong chemicals like ammonia and peroxide to alter hair color deep within the strand. It produces results immediately but can have long-term negative effects. While effective, these methods carry risks such as allergies and hair damage.
If you’re looking for gray hair solutions that support natural hair color restoration and hair health, the Mayraki Anti-Gray Hair Color Restoring Treatment is the better choice. While the process will take a bit of patience, the long-term benefits are so worth it. It’s a perfect example of how science and nature can come together to create a product that’s innovative, effective, and gentle.
