## Questions & Answers

**Q: Is the fine hair shampoo vegan?**
A: No it will not fade your color.

**Q: What does it smell like?**
A: One of the best smelling shampoos I’ve ever used! Light but still clean and a little floral? The perfect amount of scent.

**Q: Does the thick shampoo add volume?**
A: This is for people with Thick hair! It does Not help to achieve thick hair. It helps to calm the frizz, moisturizes and makes it shiny and sleek and a lovely rose scent.  Do not buy if you want to thickening your hair! This is not for fine/thin or thinning hair. It makes most people with fine/thin or thinning hair overwhelmed by the scent and the amount of conditioning. Usually leaving the hair feeling oily, weighed down and leaving them overwhelmed by the strong scent. I have not tried the fine hair shampoo but I can not recommend using this if your hair isn’t Thick! It works magic on my horse main (I’m Italian) and I have high end, low end and in between and this has given me the best results.

**Q: Can this be used on super fine hair?**
A: Yes, my hair is super fine and curly and I love the shampoo. Just don't like the container opening. Difficult to open due to my arthritis
