66 with thick hair? I envy you! I could cry, I'm 49, fine hair, long, frizzy, dry. NOTHING I do seems to help it. I wash it every 4 days, 3 usually, and let it dry naturally, which is wavy. But when the humidity hits it, I look like I've stuck my finger in a electric socket! I've had it short (2 inches all over) but since Covid struck, I let it grow again. I know I'm stressed (a lot going on) and my hair is paying for it! I don't want to have it cut short as it's actually more work. It's light brown with "skunk" streaks underneath but from afar look like natural highlights. I used to dye it in my 20's and early 30's various shades of red but now I can't be bothered! I also DON'T have a little elfin face for pixie cuts!
