When exploring ingredient lists, the quest to avoid sulfates and silicones demands a keen eye and a little chemistry knowledge. Sulfates often masquerade under names like sodium lauryl sulfate or sodium laureth sulfate, which are popular foaming agents but notorious for stripping natural oils from hair and skin. Similarly, silicones don’t always wear their true names openly. Look for suffixes like -cone, -conol, or -siloxane – examples include dimethicone, cyclopentasiloxane, and amodimethicone. These ingredients form a protective layer but can lead to buildup, dullness, and reduced moisture absorption over time.

  • Sulfate Indicators: sodium lauryl sulfate, ammonium lauryl sulfate, sodium laureth sulfate
  • Silicone Clues: dimethicone, cyclomethicone, amodimethicone, phenyltrimethicone
