- 3-IN-1: LEAVE-IN + HEAT PROTECTANT + ANTI-FRIZZ FINISHER - One bottle replaces three products. Use it as a daily leave-in on damp hair, as a heat protectant before blow-drying or flat-ironing (up to 450°F styling tools), and as a midday smoothing touch-up. Saves room on your shelf

- WORKS ON EVERY HAIR TYPE - FINE TO THICK, STRAIGHT TO CURLY - Fine or thin hair? Use 1 drop. Medium or wavy? 2 drops. Thick, curly, or coarse? 3 drops. Safe for color-treated, bleached, highlighted, keratin-treated, and chemically processed hair. Sulfate-free, paraben-free, alcohol-free, cruelty-free
- ONE BOTTLE LASTS 4-6 MONTHS - LESS THAN $0.15 PER USE - At just 1-3 drops per application, this 4.25 fl oz bottle outlasts budget-friendly serums and costs a fraction of premium salon brands.

## Questions & Answers

**Q: Does this product have Formaldehyde and sulfate?**
A: No,this unique Keratin Hair Serum doesm't contain Formaldehyde or Sulfate

**Q: Is this product safe for keratin treated hair ?**
A: I use this product once a week and I cant image it not being safe.  I have never had the keratin treatment at a hair salon, but I use a leave in conditioner, heat treatment and infusion therapy keratin replenisher daily on my color treated hair and I have no issues.  Plus the keratin protein weekly on top of all the other products with no issues.

**Q: Is is this product most effective when applied to dry or wet hair?   many thanks.**
A: I think the conditioner is meant for wet hair and this is to apply to dry hair after it's been fixed or blow dried. After I'm done blow drying it, I apply it and it gives it a nice shine. But I'm sure it'll have the same effect if applied to wet hair and then have it blow dried.

**Q: You add this to wet hair ? Is this a heat protectant?**
A: Yes, you add our unique Keratin Hair Serum on damp hair.
Please see the Directions section: "Apply a few drops to your palms and spread thoroughly on dry to damp hair from hair root to tips."
It Is a heat protector, although you will see it evaporates as it is water based.
