I've been thinking about getting my hair dyed. What are the signs that it's time to dye it?

1.  If you're noticing more gray hairs than normal, or if your hair is starting to look dull and lifeless, then it may be time to consider a hair color change.
2.  Another sign that it might be time for a hair color change could be if you want to experiment with different looks, like going from blonde to brunette, or vice versa.
3.  You may also notice changes in your scalp condition such as increased shedding, dandruff, or flaking.
