Safe to do highlights?

Alison, 🌈 👶🏻 born 7/26/19

I’m 14w4d today and haven’t done highlights since November. I don’t put color on my scalp at all I was just going to do half a head of highlights. I go to aveda salon. Is this safe you think? My doctor did say after the first trimester is fine but with two prior miscarriages I’m still cautious. I think it’s fine as I’m not putting color on my scalp. Anyone else do highlights around 14 weeks? Thanks!
