I have natural blonde hair and have dyed it many times to brown, very dark brown and now red. Now I am having to dye it every coule of weeks as my blonde roots are coming threw, is there any way of taking all the hair dye out of my hair and go back yo my natural hair colour?

This is a tough situation. I would suggest going to a professional hairstylist for this one. You can have many problems arise from trying to correct this at home. However, if you choose to handle this on your own, here are some suggestions. Try using dish soap such as Palmolive for a week or so to shampoo your hair. Use up to twice daily. If your hair starts to feel dry, you will need to deep condition. If you don't have the opportunity to go to a professional hairstylist for the conditioning, you can use a regular moisturizing conditioner. Put on your dry or damp hair generously and cover with plastic shower cap and wrap with a hot, damp towel for 20 minutes and then rinse. Or you can use an at-home recipe of 1 cup mayo (room temperature), 1/2 cup olive oil, and 3 egg yolks. Follow with plastic cap and towel and sit 20 minutes before rinsing. As for the color, there is a chance it may not fade completely because it did go so dark. Consider having some highlights put in to blend the new hair to the colored hair while it grows out.
