Naturstyle has recently rebranded to Naturtint. Some products may still be sold under the Naturstyle label.
What option now
I have used this colour 3n or 4n for around 20 years and loved it. Now my scalp burns and itches each time I use it and I am not game to continue the usage. I notice the product has a sign "improved formula" on the package. Maybe that is the problem.
