Why Oils Belong in Skincare (Even if You Have Oily Skin)
Facial oils play a crucial role in maintaining the skin barrier. From fatty-acid-rich plant oils to antioxidant protection, oils can help regulate imbalance rather than create it.
To show how gentle Jevie products are, Dr. Mesri conducted a simple radish seed germination test. Seeds react quickly to chemicals, making them a clear indicator of toxicity. The result: while seeds thrived in Jevie solutions, they failed to germinate in baby shampoo — proving Jevie creates a safer, less toxic environment for growth.
THE SHAMPOO VS. BABY SHAMPOO
After 72 hours under room conditions, radish seeds germinated successfully in Jevie solutions, while no germination was observed with baby shampoo.
1:1 Water : Shampoo
Seeds in Jevie solution began to sprout, while no germination occurred in baby shampoo.
2:1 Water : Shampoo
Even at this dilution, Jevie supported healthy seed growth, while baby shampoo prevented germination.
3:1 Water : Shampoo
Seeds continued to germinate with Jevie, but none grew in baby shampoo solution.
Setup
Dilution Ratios Tested
The test was conducted under room conditions for 72 hours. Radish seeds require a minimum of 20 °C to germinate, ensuring a natural environment for growth.

This test highlights how Jevie formulations are less toxic and more environmentally friendly. If seeds can germinate in the presence of Jevie Shampoo, it shows the product is safe, natural and gentle—not only for people but also for the planet.

Dr. Shahram Mesri, founder of Jevie and plant scientist with a PhD from Tokyo University, has dedicated his career to creating natural, science-backed solutions for healthier skin and hair. Guided by the belief that “Nature is above all,” he leads the research behind every Jevie formula.
THE SHAMPOO
This simple but powerful test shows that Jevie is not only effective but also naturally safe and environmentally friendly.
