Colouring my hair?

Hi, im not sure of what i want to do but i have some ideas but i dont know if all of them will work. I have naturally black hair, so everyone keeps saying i would have to bleach it for any colour to show up. Im thinking of either doing:

-Dying it all that blue/black, purple/black colour

-Dying it a rich deep brown colour

-Getting the back portion of my hair dyed in either blue or red or just any shade of an obvious brown (for this would i have to have it bleached? and which colour would last longer? because i really have my heart set on the blue)

-And, how damaging is it really to colour your hair?

-And the Loreal Colour Pulse, would those even show up in my hair or would it be a waste of time?

Oh and if i have to bleach it for any of these options, im assuming the colour fades and i would have to keep dying it every 8 weeks right? oh and which of these options are the least damaging?

Thank You!

Colouring my hair?

Keep in mind that if you go darker, it will be alot more difficult for you to go lighter if ever you wanted to in the future.

A rich deep brown colour might work if you get it done professionaly at a salon.

Do actually see the red or blue you would need to bleach it.

You will damage your hair by color from the pharmacy, because they don't really have any treatments in them. I know that the professional colour will prevent damage done to your hair. BUT it all depends on how healthy your hair is to start off with.

L'Oreal color pulse is a semi permanent color, which means it does not have any ability to lift your hair a level to give it the color you want, so you will just be wasting your money.

Have you ever consideed putting streaks in your hair? It will probably be even more fun than just going all one colour. Blue or red streaks in certain areas of your hair and look very good and you aren't damaging your whole head with streaks!

Good Luck!
