Wow, being a hair dresser with nickel allergy can't be easy! Scissors, hair pins, combs/brushes... and probably other things I can't even think of... I definitely recommend a nickel testing kit (my fav is in my product guide) and purchasing from a hair accesory place with a good return policy.
Isn't it crazy how much nickel creeps into food? People with nickel allergy should absolutely do their fair share of research on nickel in food.
You know, I feel like yoga pants, flip flops and no bra sounds like a good idea lol! Thank you sharing the nickel allergy / tattoo information. Finding a responsible artist you trust is definitely key.
Good luck in your journey, Mia!
