Back in 2005, the bottom 6 inches of my hair were fried from curling iron and flat iron use. I originally planned to trim it off a little at a time and had two 1/2" trims approximately two months apart. However, my hair wasn't growing much, and one day I snapped and had the remaining 5 inches cut off all at once. For 2 days I went around thinking "what have I done?" and feeling sad. After that it was so wonderful to enjoy my silky hair instead of fighting with bad ends every single day. AND it began to grow again. It was so worth doing; I'm not kidding.
