L'Oréal Professionnel Inoa Permanent Hair Dye now has a new formula with improved results. This ammonia-free hair dye offers a permanent coloring solution with optimal results and great comfort. Indeed, this new formula has some features that differ from the old one. Firstly, the formula is vegan, free from ingredients of animal origin. Secondly, it is a fluid formula thus being faster and easier to apply and extend to the lengths as well as to mix and rinse. Thirdly, this new formula offers 48% more shine than the previous one. And lastly, it presents a more sustainable image with a tube made of 95% recycled aluminum. At the same time, this formula features the exclusive ODS (Oil Delivery System) patent with 60% oil, which guarantees a high-impact color, shine, and scalp comfort.
Equally important, this hair dye lightens the hair up to three levels and grants 100% of grey hair coverage. Always delivering a professional result, this hair dye guarantees long-lasting color with healthier-looking hair. With a wide range of colors for all hair types and textures, it offers solutions for anyone.
This product was developed for professional use only and should not, therefore, be used at home. Mix L'Oréal Professionnel Inoa Permanent Hair Dye with the suitable L'Oréal Professionnel Inoa ODS Oxydant Riche developer depending on the hair condition and preferred technique. Use a ratio of 1:1. Apply to the hair adjusting the technique to the desired results and access developing time accordingly. After developing, gently emulsify the product to remove the color from the scalp. Then rinse thoroughly until the water runs clear. Lastly, shampoo twice with L'Oréal Professionnel Série Expert Metal Detox Shampoo or L'Oréal Professionnel Inoa Post Shampoo.
In this section we answer frequently asked questions about L'Oréal Professionnel Inoa Permanent Hair Dye
The numbers on a hair dye identify its shade. The first number is the level, which shows how light or dark the color is, on a scale from 1 (black) to 10 (lightest blonde), with some brands going up to 11 or 12 for very light blondes. The number after the dot, comma, or slash is the tone, or reflect: most brands use 1 for ash, 2 for iridescent or violet, 3 for gold, 4 for copper, 5 for mahogany, and 6 for red, while 0 means a natural tone. So a 6.3, for example, can correspond to a level 6 (dark blonde) with tone 3 (gold), making it a dark golden blonde. A second tone number, like in 6.34, adds a subtler secondary tone, and a 0, like in 6.60, makes it more intense.
Not every brand uses the same system: the same number can stand for a different tone from one brand to another, and some brands use letters instead. The shade information each brand gives for its own hair dye is always the most reliable guide.
