Ammonia-free hair coloring is here

Here comes a "revolution" in hair coloring, according to scientists. That would be scientists at L’Oréal, who say they have found a way to replace stinky ammonia with a new, odorless, substitute.

You are probably dying to know that ammonia has been a part of hair coloring since L’Oréal's founder invented it a century ago this year. The new dye is called INOA for Innovation No Ammonia, which seems sensible. L’Oréal claims that, in addition to being free of ammonia smell, INOA feels more like a thick skin cream than regular hair coloring products.

INOA is already used in salons in Europe. It will be available at salons in the US and Canada early next year and eventually in home hair dye, the company says.
