## Questions & Answers

**Q: What is the list of ingredients in their order? all we know from the page is it has keratin and is sodium chloride free. thanks**

**Q: Can you use this Keratin on naturally curly yet fine hair? I don't want it to go straight. Thanks!**
A: I have curly hair and I use it on my hair once a week

**Q: The ends of my hair seem a little dry after my keratin treatment.  Will this product help?**
A: This product makes my hair shiny and smooth when used with blow drying.  It should help your ends.  I always use a keratin enriched conditioner after shampooing which likely contributes to making my hair smooth.  If your ends are dry after your keratin treatment, perhaps the stylist is a bit heavy handed with the flat iron.

**Q: I have natural curly/wavy hair that is gine and gets frizzy. Will this help my hair, without weighing it down.**
A: It does not say light so yes it will weigh your hair down
