## Questions & Answers

**Q: Is this product 100% authentic?**
A: After seeing this question, a further investigation was made and a comparison with the one from a local beauty shop definitely indicates that it is thinned out and not the “real thing”, not 100% authentic, in my opinion.

**Q: Why is this 17.99 and same item is $34?**
A: >> Why is this 17.99 and same item is $34?

The wholesale price we get from the manufacturer is DEFINITELY MUCH higher than $17.99.
Take a chance when you buy such items.  Counterfeits are everywhere in eBay and Amazon.

**Q: CN I use this on dry hair?**
A: I use it only on dry hair.  I have curly hair and apply it every morning and as needed throughout the day if I’m out in humid weather.  It keeps it from getting frizzy and stays smooth most of the day. Just don’t put it close to your roots or it will look greasy.

**Q: Why are A batteries required???**
A: It doesn’t. There must have been a typo in the listing.
