What hair dye to buy?

I’ve been dying mine and my friends hair for over 7 years. I’ve experimented with every type of dye out there. I’ve screwed up my hair a million times, but learned from every experience. I have naturally dark hair, and started out dying it reddish brown, and I usually go from dark brown to light brown, and sometimes black when I’m tan. As for your blonde hair, I highly recommend NOT going too dark. For a first time dye, go no more than two-three shades darker than your natural hair color. Say a very light brown. Two reasons I say this: If you go too dark, you’ll look gothic, and you’ll probably look very pale. Second, once you dye your hair dark, it’s almost impossible to go back to blonde without having to bleach it which is EXTREMELY bad for your hair! After I dye my hair black, it takes me several treatments in order to get it back to a lighter brown. Some good box dyes you can get at any grocery store, wal mart, or drug store. I recommend Loreal Preference, and any Herbal Essences dye. Since your hair is still natural, it might be smarter buying a low or no ammonia formula like Revlon Colorsilk. It’s much gentler on your hair. What type of hair do you have? Thick or thin? I have very thick hair and people are surprised my hair hasn’t fallen out as many times as I’ve dyed it. If you have very thin, unhealthy hair, do not dye it often. Only once every two to three months. If you go darker, you will always get the blonde root, its your natural color, no way of getting around it. The darker you go, the more obvious the blonde roots will be. So stick to a light brown and use a Root Touch up whenever your blonde roots start to show (you only dye your roots to match the rest of your hair) p.s.
