Keratin Treatment Questions & Answers – Inova Professional
Keratin Treatment Questions & Answers – Inova Professional
Keratin treatments can be confusing — especially when every client has different hair, goals, and expectations.
With over 40 years of behind-the-chair experience, Inova Professional created this guide to help stylists and clients understand our treatment systems clearly — and select the right one with confidence.
What does a keratin treatment actually do to the hair?
Keratin treatments smooth the hair cuticle, reduce frizz, add shine, and make styling faster and easier.
They do not permanently change the hair structure — they enhance and protect it.
Inova formulas include keratin proteins and nutrient oils that improve hair quality over time — not just appearance.

Stylist Advantage:
Flat iron temperature, timing, and number of passes fully control the final result — from soft finish to stronger smoothing.
How long does each treatment last?
When applied professionally and supported with sulfate-free aftercare — these are real results seen in salons:
| Treatment | Real Duration |
|---|---|
| One-Step Kera-Quik | Up to 4 months |
| 24 Hours Gold Keratin | 4–6 months |
| Simply Silk Vegan | Up to 6 months |
Important:
Sulfate shampoo will strip keratin instantly — aftercare is what decides durability.

Will keratin make hair flat or greasy?
Only if the stylist chooses to make it flat.
Keratin is fully controlled through:
-
Heat level
-
Processing time
-
Number of passes
-
Formula selection
A trained stylist can deliver soft finish OR 100% straight — using the same product.
Technique creates the result — not the product alone.
Can keratin damage the hair?
No — only poor-quality formulas or incorrect technique cause damage.
Inova keratin systems are designed to strengthen hair, protect the cuticle, and improve texture over time.
When hair is dry or processed, stylists often use maintenance treatments:
| Treatment | Purpose |
|---|---|
| Pro Fusion Therapy | Used after keratin to prolong results |
| Flex-Fusion Therapy | Used without keratin to repair & reduce frizz |
What is Pro Fusion Therapy?
This is NOT a keratin treatment.
It is a post-keratin booster used to maintain results, protect the hair, and extend the life of the treatment.
✔ Applied after keratin
✔ Adds hydration & shine
✔ Supports long-term hair health
Pro Fusion Post-Keratin Booster Treatment
What is Flex-Fusion Therapy?
Flex-Fusion is not keratin and does not straighten.
It is a stand-alone professional treatment used for frizz control, hydration, and repair — for any hair type, whether keratin is used or not.
✔ Perfect for clients who do not want keratin
✔ Helps repair hair after color, bleach, or heat styling
✔ Can be used between keratin services — but not required
✔ Suitable for any level of salon or stylist
Flex-Fusion Frizz Reduction & Repair Treatment
How soon after a keratin treatment can I wash my hair?
Stylists recommend waiting 24 hours before washing.
This allows the treatment to fully bond to the hair.
From that point forward — sulfate-free shampoo only.

How often can I repeat a keratin treatment?
Every 3–4 months is ideal.
Hair often improves with each session when correct aftercare and professional technique are followed.
Is keratin safe during pregnancy or breastfeeding?
Always consult your doctor. Even with formaldehyde-free formulas — only a medical professional can provide correct advice.
