## Questions & Answers

**Q: Can this product be used on lightened or color treated hair?**

A: Women can use this product too if she wants to darken her grays.  Her white hair will gradually become darker, but it will NOT match the original hair color.

A: It will give you a smoke grey. Natural grey looks better. I stopped using it.

**Q: How often should you use this to start seeing results and will my hair fall out?**
A: Hello, you should use this product as you'd use a regular shampoo (once a day) for 1-2 weeks until you see results. 
Kindly note that each hair is different. In some cases, results show in the first washes, and in some other cases in 1-2 weeks. 
I hope this helps!
