## Questions & Answers

**Q: How do i know this is the real product? when i google the company it looks like its an indonesian company. how do i know it's authentic?**
A: My bottle of Nioxin Cleanser (shampoo) says it is a product of the Wella Corporation in Woodland Hills, California.  There is an 800 # for questions:
800-935-5273.

**Q: Is this product also a detangler?**
A: This is a really good question I will be happy to answer for you today. This is our Nioxin Scalp and Hair Treatment after shampoo and Conditioner you towel then apply 2-3 pumps on your finger tips and masaage into your scalp leave let dry 1 minute and then you would be able to apply any products you normally would including a detangler. 
This is not a detangler as it is to promote healthy hair growth and stimulates the scalp. I hope this answered your question today.
Have a Fabulous Hair Day!
