I have been coloring my hair since 4 years ago. But I didn't do it periodically. Only when I feel the need to coloring my hair. My first attempt... I call it as a failure, because my hair color not really changed a lot and far from my expectation. It's also my fault who bought dark color lol. my hair is black and I dye it with dark brown without bleaching, imagine how it is looks like :p It was about I just graduate from High School. To tell you the truth, I know nothing about beauty product  back then. let's say I become more girly after graduate from high school.

So the second attempt, I decided to bleach it because I am too curious with the result if I bleach my hair first. I searched the risk of bleaching. It said it will makes your hair very dried, looks dull, and you need treatments after that like getting hair spa once a week. Because I am too curious, I still did it, and by myself. It's hard to see if the bleach powder are spread great or not. I highly recommend if you want to do your bleaching step at home, ask help for people to apply it for you, cause mine is messily not even T^T. Although I am satisfied with the result. It was very orange-ish (used to think it will be like yellow to the white :P). ah you need Leave it for days before you dye it again.  It is true after the bleaching process is done, you hair will be very very dry, so you really need to apply hair mask once a week.
