A member asked:
The ingredient ceteareth 20 is in my hair conditioner, is it bad to leave this ingredient on my scalp? i heard it's a skin perpetrator.

Penetrator: This is safe as long as there are no toxic contaminants. It is not toxic itself but facilitates absorption of various molecules deeper into skin. If it is a brand from an established company it should be safe.
