When Skin Feels Reactive, It’s Often the Barrier
When skin feels sensitive, tight, or unpredictable, the cause is often a weakened skin barrier — not your skin type.
Science-Backed Protection for Your Hair Color
To evaluate Jevie THE SHAMPOO, we conducted a comparative laboratory test against a leading ‘damage control’ shampoo. Under harsh washing conditions, Jevie THE SHAMPOO preserved hair color while the commercial shampoo showed significant fading. The results prove Jevie’s superior ability to protect and prolong color.
THE SHAMPOO VS. COMMERCIAL SHAMPOO
The Results Are Clear
After three hot-water washes, the commercial shampoo showed marked fading, while Jevie THE SHAMPOO retained its dyed color with minimal change.
-
COMMERCIAL EXTRA DAMAGE REPAIR SHAMPOO
Hair lost most of its color, fading back to original color.
-
Jevie THE SHAMPOO
Hair color remained vibrant and nearly unchanged.
Why Hair Color Fades
Hair color doesn’t just disappear—it escapes. The outer cuticle layer of the hair works like tiny protective scales. When it’s damaged or lifted, dye molecules leak out, leaving hair dull and faded. Many shampoos with harsh surfactants and high pH levels speed up this process.

HOW WE TESTED
- Hair & Pre-Treatment
Two sets of natural gray human hair were prepared and uniformly dyed dark gray using standard oxidative dyeing procedures. - Grouping
Dyed hair was split into two groups: Jevie THE SHAMPOO (pH 5.6) and Commercial “damage control” shampoo. - Stress Test Conditions
To accelerate color loss, hair was washed in hot-water conditions. Both shampoos were warmed prior to use. - Wash Cycles (×3)
For each cycle, shampoo was applied to the wet tress, massaged, then rinsed in hot water. This was repeated three times per group under the same conditions. - Rinse & Dry
After the third cycle, tresses were rinsed thoroughly and dried without conditioner or styling products. - Evaluation
Color retention was assessed by visual comparison under standardized lighting and photographic documentation (same background and white balance). - Controls for Fairness
Application time, water exposure, wash count and handling were kept identical for both groups.
What This Means for You
With Jevie THE SHAMPOO, you can enjoy your color longer and reduce the need for frequent re-coloring. That means healthier hair, less damage and vibrant results that last—proven by science.
THE SHAMPOO
THE SCIENCE BEHIND JEVIE
- Balanced pH (5.6): Close to the scalp’s natural level, keeping cuticles sealed.
- Gentle Cleansing: Plant-based surfactants clean without stripping.
- Cuticle Protection: Preserves the outer layer, locking color inside.
This unique combination means Jevie cleans effectively while helping your hair stay healthy, shiny and brilliantly colored.

Conditioner is often used to fix what harsh cleansing has taken away. When shampoo respects the scalp, pH and hair structure, conditioner may no longer be essential.
