Every month and half or two months I dye the roots of my hair and my favourite hair dye is the Syoss oleo intense. The smell is not as strong as other hair dyes and doesn’t dry the hair. The colour intensity is also very nice and when it fades still has a beautiful shade. The 6-10 is my favourite shade. I use it to dye the roots. Twice a year I dye the whole hair and then I mix the 6-10 with the 4-50. LTKeurope LTKfindsunder50 LTKbeauty
