I want to sew fake hair into my own hair, help?

I'm blonde and I want to sew in fake multicolored hair (blue, green, purple, etc).

How do I go about doing this?

Also would I still be able to put it up?

How long would it stay in with showering?

I would go to a hairdressers i think they put in coloured extensions at a reasonable price (depending on how may you want). You can put your hair up as normal as they put it in so that you cannot tell that they are extensions as the part that holds it in your hair is hidden (i dont know how they do it). Youc an shower as normal. I had extensions once and they lasted about 8 weeks but if your only having a few streaks then they should last longer. You just pull them out when you are ready. They wont fall out on their own. Good luck.

Just go to a salon and tell them you want colored extensions.
