This is simply a gorgeous hair color. One problem many women with gray hair have is yellowing of hair from the sun, hard water and other environmental factors. To keep this from happening, it's best to neutralize the yellow. Do this by washing hair twice weekly with a color-correcting violet shampoo. Make sure you keep the shampoo on your hair long enough. You may find you need to keep it on your hair for up to 10 minutes.
Another problem women report is that their hair appears dull. Washing your hair with a clarifying shampoo weekly should do the trick. You can also rinse hair with apple cider vinegar once a week. This should remove any build-up from hair products. If this doesn't work, get a clear hair-gloss treatment monthly at your salon. It's relatively inexpensive and only takes about 20 minutes.
