Brassy tones are colors in your hair, like copper colors, that can wash a person out depending on their skin tone and the rest of their hair color. It can also make the hair look unnatural if not done correctly, unless it is a natural color.
Fancifulashley pretty much covered it. Go to a beauty store to find products that can help eliminate them. The store clerk can help you find them.
:) Also, adding some darker low lights can help fix the problem with blondes which is where the brassy tones usually occur.
As a licensed stylist with over 18 years of experience, Brassy tones are the shades that reflect orange copper...It use to be no one liked brassy tones. From your photo above you look pretty blonde to me. A past trend was carmelizing hair with 3 shades...brownish, blonde and yellow gold.
If you like the color and your friends thinks it is cool just leave it. I am surprised she did not suggest just putting a toner on you to take down what she saw as brassy. Good luck!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
