Ion Permanent Creme Hair Color 4N Medium Brown, Vegan, Cruelty Free, PPD Free, 100% Gray Coverage, Long Lasting, Fade Resistant Color, 2.05 oz

I decided to try this hair dye after being reassured by its claim of being PPD-free, as I have a known sensitivity to PPD. Unfortunately, during the patch test, I experienced skin rashes and irritation—exactly the kind of reaction I was hoping to avoid. This raises serious concerns: either the product is not genuinely PPD-free, or it contains another equally harmful chemical causing similar reactions. The whole point of purchasing a product labeled "PPD-free" is to avoid such issues, and this one completely failed to deliver on its promise. If you have sensitive skin or chemical allergies, I’d recommend being cautious with this product. For me, this was a disappointing and frustrating experience. Transparency about ingredients is critical, and this product left me with more questions than trust.

This does not turn your hair the color it says it will. I had almost white blond bleached hair and it turned it neon purple.

طريقة الاستعمال غير واضحه ويبدو ان هنالك مواد اخرى لم ترسل او على الاقل لم يتم ابلاغي بانه يتوجب علي شراء مستحضر اخر يخلط معه عموما اشتريته لانه خالي من PPD على اساس ان معي حساسيه من هذه الماده ولكن اتضح ان لدي حساسيه من جميع صبغات الشعر

I’ve previously dyed my hair many times and my hair has never fallen out, but with this product that I’ve never used it did. It’s not even worth it because the colour did nothing to my hair

No difference in the hair color. Difficult to actually find the instructions. When I finally did on the inside of package the print was so small I needed a magnifying glass to read and even then it was unclear. Terrible smell. Would not recommend this product to anyone.

I have been using Ion hair dye for nearly a decade. I've used several different black dyes, but Ion is the only at home hair color that I have used that gives me a natural look. Other black dyes make it appear as though I am wearing a wig. Ion also gives my hair a nice shine and healthy appearance. Other dyes have actually damaged my hair, but not Ion. The color is long lasting. It starts to dull after 3 months. For me, it takes 6 months for the dye to fade out. So if you are wanting to change your hair color from black, you should be able to safely after 6 months, from my experience. I have been able to successfully strip the dye after the 6 month mark to then dye lighter. Like purple, green, red, blue, even grey.
