## Questions & Answers

**Q: Does it go the colour on the box?**
A: It did for me. Really happy with the colour. I have long thick hair and one wasn’t enough for me so about to order two.

**Q: Am I supposed to use the full sachets in one application**
A: Yes, the sachets within the PurePlex colourants are to be used in one application. Your hair will then feel the full effects of the Bond Reconstructing Treatment and Conditioner during your colour process.

**Q: Is the 4.0 brown also a neutral tone?**
A: PurePlex Colour 4.0 is a Dark Brown, there are no warm or cool tones to this shade as its a neutral shade. However, pending your hair history the end results from applying this shade may vary and without seeing your hair in person we cannot guarantee your end result.

With any colour application at home, we would recommend a patch & strand test is conducted. As this will allow you to check the results you can expect for your hair type and base, enabling you to see if you are happy with the colour, condition and you achieve your desired result
