S and D means Search and Destroy, a method of removing damage from your ends, or along the hair strand.
There are different methods:
1) take a thin section of hair and twist it gently. The damaged hair sometimes will pop out and you can snip off the split or white dot. Always be sure to use SHARP shears, or you'll just be creating more white dots.
2) take a few strands of hair and search down the length for any damage
3) some people braid their hair loosely and snip off any damage
If you have too many splits at the bottom of your hair, then a small trim might be more effective.
