What the evidence says

We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.

Look it up yourself

We would rather point you at the shelf than summarize something you can’t check. These are the same places we search:

  • PubChem — what the substance is, chemically — names, synonyms and structure
  • PubMed — every paper indexed by the US National Library of Medicine that names it

These are starting points, not our findings — we haven’t run them for you. A substance whose name is also an ordinary word (“Heart”, “Alanine”, “Water”) will return papers that are not about the ingredient at all.

Context

Used in rinse-off and leave-on hair products alike, typically at low percentages. Silicones of this kind sit on the hair surface rather than penetrating skin, which limits systemic exposure concerns.

Insufficient dataToo little has been studied to say either way.

Rumors

  1. Bis-aminopropyl dimethicone bonds to the damaged areas of the hair cuticle and repairs them.
