## Questions & Answers

**Q: can you reuse the unused part?**
A: Yes, the developer is not time-sensitive for use. Just tightly cap the bottle until the next use.

**Q: What ratio of this developer to the American Crew precision blend products do you use?**
A: I just estimate how much I will need to do all my hair and use that amount.  I am never very exact.  The same with the coloring.  I just add 3 or 4 big drops, mix it together and  let it set for a couple of minutes before applying.  It is a great product and works very well.  I like a little grey left so it looks very natural.  This is the best hair color that I have tried.  You can also vary the length of time you leave it on depending on the look you want.

**Q: what's the size or how many ML is this? the pictures says its 16.9 oz but in the title its just 15.2 oz. thank you very much.**
A: It's what the bottle says, 16.9 fluid ounces.

**Q: When will you carry this item again?**
A: Yes it is good for about a year
