FAQ 

Q: What does GK Hair Serum do?
A: It smooths hair strands, reduces frizz and flyaways, adds hydration and shine, and helps make hair softer and more manageable. It also acts as a protective barrier against heat styling, humidity, and environmental damage. 

Q: Who should use it?
A: — Clients with dry, frizzy, coarse, or damaged hair.
— People with color-treated or chemically treated hair who want to maintain moisture and softness.
— Anyone wanting shine, smoothness, and easier manageability, especially those who heat-style or live in humid climates (like Miami).
— Clients looking for a lightweight serum that won’t weigh hair down. 

Q: What benefits does it offer compared to a regular conditioner or shampoo?

• Provides instant smoothing and shine — a serum coat rather than a deep rinse, making it ideal as a finishing/ styling step.

• Adds heat protection and environmental defense — useful for clients who regularly blow-dry, straighten or style their hair. 

• Keeps hair lightweight, soft, and manageable — no heavy or greasy residue. 

• Complements treatments or color — good for maintaining hair health post-treatment. 

Q: How should it be used for best results?
A: Use after shampoo and conditioner on towel-dried or dry hair. Apply a small amount (a few drops), rub between palms, and smooth it through mid-lengths to ends (avoid heavy application at the roots to prevent greasiness). Then style as usual — blow-dry, air-dry, or flat-iron. For extra smoothness, you can also apply a small amount as a finishing touch on dry hair.

Q: What kind of results can clients expect?
A: Softer, shinier, smoother hair with reduced frizz and flyaways; easier detangling and manageability; a sleek, polished finish after styling; better moisture retention; and a protective barrier against heat/styling damage. 

Q: Why should salons or stylists carry this serum?
A: Because it’s a versatile, high-demand finishing product that addresses common hair concerns (frizz, dryness, dullness). It complements many hair types and can help maintain results after color, keratin treatment, or chemical processes. It’s an easy retail or add-on product — ideal for clients wanting healthy, shiny, manageable hair between salon visits.
