So my hairdresser announces that she’s going on holiday and my hair desperately needs a touch up. In my desperation I discovered this Colour Refresh shampoo from Maria Nila. You leave it in for 3-10 minutes and the color stays in up to 10 washes. I have blond hair so I went for the subtle Sand colored one. My hair turned out beautiful golden, maybe next time I will leave it in for more than 3 minutes.
