What have I done?

So, this year, for the first time ever, I dyed my hair. I went fire-engine red for a while, which was fun. Then I went burgundy, which was also fun. Then, on Sunday, I was ready to go blonde again. Well, it turns out that is not as easy as going dark. I freaked out a new hairdresser when I asked her to make my wine-colored (or grape juice colored, depending on your denomination) tresses go back to their natural color. She wasn't okay with bleaching it and recommended I stay with purple because it looked nice. Yeah, not happening.
So, I went to the CVS and bought this stuff called Color Oops. It smells like a fart died, but it did get a lot of color out. It's now the color of a penny.
Today, I went to a professional again (different place) and she said my poor, abused hair needed at least a week to recover and then she would work on it. It's dry and smells.
That made me nervous. What have I done to my poor head? I felt guilty and scared and bought some very expensive conditioner. But the truth is, I can't ever undo it. The hair is changed. The color may be made to look similar, but it won't be my color.
It was a good learning experience, and a small lesson of what life is like. Things happen that can't be undone. I make mistakes, and then in trying to fix them, I could very well make them worse.
Which is why I'm grateful for this promise today, found in Matthew 10:29-31 "Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from your Father. And even the hairs of your head are all numbered. So don't be afraid; you are worth more than many sparrows." (emphasis mine.)
How cool is that? I am worried about my poor copper-penny hairs, and so is God. And while I have caused the damage, He still knows the number. I can't bleach his love out or cover it with purple so He loses track of the nine-hundred-and-forty-second hair from the left.
And in life, there is no mess too big OR too small for God to care about. God, Creator of stars, suns, moons, galaxies, ants, zebras, leaves, lightning....God loves you so much, He watches you sleep at night, gathers your tears, relishes your laughter, and even knows the number of hairs on your head, no matter what color they are today.
