My greys are stubborn so the color (I went with a demi this time) barely did anything or nothing at all.
I'll take a picture either later today or maybe even just wait til tomorrow for the cut. Depends on what my hair wants to do - which isn't much because it's too silky at the moment.
I've been planning to do this for a few weeks (so I wasn't doing it on a whim because other people were getting lopped. ) I was waiting for hubby to go on his trip so I could do it while he was gone and come back surprised. Except the grey thing didn't work out.
If I didn't color my hair, I'd be completely gray -- so doing it every 4-5 weeks is a must. When I first started coloring (about 20-25 years ago) I wasn't able to do the demi-colorant because it wouldn't touch the gray. I have to use the permanent coloring.
I usually start seeing the roots at about 3.5 - 4 weeks. That's usually a good sign I have to do them up.
I was having my hair professionally colored for a few years but I was still having to go back and have it done at 4-5 weeks. Even though it was nice not to have to do it myself, it's much cheaper this route.
