## Questions & Answers

**Q: Do you use this when your hair is wet or dry? (I just have a sample with no instructions).**
A: Wet, you don't want to put oil on dry hair

**Q: I can't seem to find the info I need on any sites. Is this product animal product free and cruelty free?**
A: The bottle states it does not use animal testing.  That being said,  I use it on my Cairn Terrier every time I bath him.  It makes his coat softer, and easier to brush.

**Q: Is is sulfate free**
A: I rea.d the bottle, and didn't see any sulfates listed.  I have been using it since 2001, and will never stop.  It is the best thing to ever happen to my hair.  It also is great on your skin

**Q: does this product contains any silicone?**
A: It has cyclotetrasiloxane, cyclopentasiloxane, and clyclopentasiloxane.  It is the best product I have ever used on my hair.
