No allergic reactions, a lovely light shade of violet on my grey hair! Many compliments. I recommend if you don&#039;t want dyed hair, just a hint of color. Very flattering I am told. I purchased the pink and also violet<br /> Violet was more subdued with a darker color on my still brown hair and a sparkle to the grey. The pink looks like a very light wash of violet/pink. So understated but hip at the same time, a young co-worker said. Surprisingly noticed by people and commented on. So thanks for the fun uplift in my life! Customer service was so helpful when I had questions. Really. Could not be more pleased. No allergy problem so far. Another brand was not tolerable for that reason So , YAY. Honest review from Lori.
