Amazing! I’ve used JFM since 2016, then this year I became extremely allergic to PPD . Hives , burnt scalp.. then tried products with TDS, same thing happened. Tried semi permanent color and hennas, all the fragrances irritated my eyes and the colors lasted a day or 2. Not to mention the blue and green undertones. Stained my shower etc . With Inochroma there is no fragrance, no burning, no stains, no stress, doesn’t stain your skin, no irritation.. just natural looking darker hair. It hides grays but gradually. Once it’s dark, keep it dark by repeating the process ( which is so easy ). I look 10 years younger, and regained confidence. JFM color is too even and fades fast and there is so much burning and discomfort.. Inochroma is a Game Changer, it entirely changes the way we color our hair!
