Question: Permanent vs. semi-permanent hair dye? Since I have to re-dye about every four weeks because the roots show, is there any advantage to permanent color?  I don't care if it lasts 6 weeks, if I have to color every 4 weeks.  Or does permanent color cover better?

Answer: Semi-permanant color lasts up to 6 weeks. That just means that it will fade off a little bit. You cannot control how much your hair grows.  It grows a 1/2 inch every monthy on average. Therefor, you will always need to color it every 4 to 6 weeks. To keep your hair healthier, I would suggest that you see a professional because it is relaxing and easier, plus everyone can tell if you color your own hair. Trust me. If you keep doing it at home, then do a retouch when needed and on the 2nd time that you would retouch the roots, pull the color to the rest of your hair the last 5 minutes to refresh it. You can use whatever you prefer too-semi or permanant.  I would use permanant to prevent fading. And don't forget a color safe shampoo! Hope this helps!
