I have lockdown hair. I have noticeable grey roots and I look old. Normally I have my hair dyed in a salon with a semi permanent dye but as I'm facing a 6 week wait minimum to get a hair appointment, I thought I should try hair dye DIY. I have never dyed my hair before myself and neither has anyone else in my household. We are all clueless.
On impulse, earlier today I bought a packet of L'Oréal casting creme gloss. I have a teen who is prepared to help out. But I'm scared I'm going to end up with dye all over my face, stained clothes and stripey hair. Please give me your best tips for not ending up like a dog's dinner.
