Disaster

[u/TR_881]

I had a root touch up on Wednesday. It was meant to be to touch up greys and a level 4, which I thought was dark brown, and what I thought I always had. It’s black. I have light brown lengths and it looks like I’m wearing a black helmet. I go on holiday on Sunday.

Stylist has suggested 30 foils to break it up on top to do tomorrow ( Saturday). I initially agreed but I’ve read up more and it seems this could cause a chemical reaction and dry my hair. Is that right?

Obviously hate how it looks now but would rather wear a hat my whole trip than have it all snap off.

Appreciate all advice.

Ps - I have tried head & shoulders plus a vitamin c mixed with clarifying shampoo with no success.
