## Description

Review: Silky Smooth - I am very impressed with this product. After first using the recommended Natural Formula shampoo and conditioner, I applied this serum to my hair. I must say that the results were immediate! My hair was soft, shiny, and manageable. I straightened my hair a few hours after applying the serum and the flat iron smoothly glided through my hair. I am looking forward to how long the serum extends the straightening. The bottle says that it extends it by 3 times. Based on my first use, I highly recommend this serum.
Review: It works good for me - I actually want this again

## 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

### ⭐⭐⭐⭐⭐ Good Product
*by L***V on September 21, 2020*

It has a nice smell and it is a great final product to add to your hair. I use it wet and on dry hair, my hair is blue so it had lots of chemical bleaching done over the years. It helps with flyaway baby hairs and does not make your hair look grease, at least not mine since I do have dry hair.
