I have been using JOICO colour 10 on my client for 6 months , every 4 weeks, until he had a reaction. I did a skin test with Schwartzkopf, his previous colour, which had a milder reaction. Then tried Wella Koleston perfect, which was fine, but the shade came out much warmer than the other two brands. He is 90% grey and desperately wants it covering. Any suggestions would be most welcome please.
