What Is Hair Gloss
A hair gloss treatment is like a topcoat for your hair, adding shine, enhancing color, and smoothing the surface without altering the internal structure of your strands.
What it Does:
- Boosts shine and vibrancy
- Enhances color tones (perfect for fading highlights or dull ends)
- Seals the cuticle for a smooth, silky finish
Key Benefits:
- Instant radiance without changing hair structure
- Safe for color-treated, thin, or fragile hair
- Low-maintenance with minimal aftercare
Color Enhancement Magic
- Blondes: Neutralizes brassiness for a fresh tone
- Brunettes: Deepens richness and dimension
- Reds: Keeps the fiery tones vivid
💡 Salon Tip: Many of our clients book a gloss right before weddings, events, or vacations for that camera-ready, reflective shine. Learn more about your wedding timeline here.
⏱️ Duration: Hair gloss usually lasts 4–6 weeks, depending on how often you wash and style. It’s a gentle, low-maintenance way to keep your hair looking healthy and refreshed.
Studies show that hair gloss treatments enhance shine, hydration, and smoothness without damaging hair structure.
What Is a Keratin Treatment?
Keratin treatments work on a deeper level, infusing the hair with keratin protein and sealing it with heat. The hair treatment helps reduce frizz, smooths texture, and provides long-lasting shine.
Benefits of Keratin:
- Reduces frizz even in humidity
- Makes thick or curly hair smoother and more manageable
- Speeds up daily styling time
- Adds lasting shine and smoothness
Studies show that keratin treatments can increase hair diameter by up to 49%, improving hair strength and texture.
✂️ Stylist Tip: We recommend a light trim before your keratin treatment. This helps seal in healthy ends for the best results.
🧴 Duration: Results last 3–5 months with proper care using keratin-safe shampoo and conditioner.
⚠️ Safety Note: Some keratin formulas contain formaldehyde or aldehyde-releasing ingredients. At Haste Urban Hair Spa, we use formaldehyde-free options that deliver smooth results safely.
Hair Gloss vs Keratin Treatment: Key Differences
| Feature | Hair Gloss | Keratin Treatment |
| Primary Goal | Shine, tone enhancement, light smoothing | Long-term frizz control, sleek texture |
| How It Works | Deposits conditioning & shine boosters on the hair surface | Infuses keratin protein and seals it into the hair shaft |
| Effect Duration | 4–6 weeks | 3–5 months |
| Results | Glossy, silky hair with subtle smoothing | Frizz-free, smooth, manageable hair |
| Hair Type Suitability | Fine, fragile, or color-treated hair | Thick, frizzy, coarse hair |
| Chemical Intensity | Very mild | Stronger; semi-permanent alteration |
| Aftercare | Simple: sulfate-free shampoo helps maintain | Use keratin-safe shampoo; avoid washing 48–72 hrs post-treatment |
| Cost & Time | Lower cost, ~30–45 minutes | Higher cost, ~2–3 hours |
| Best For | Quick shine boost, soft finish | Long-term smoothness, frizz control |
💬 Both hair gloss and keratin treatments contribute to surface smoothness and shine, reducing frizz and enhancing hair aesthetics.
👉 In short:
- Choose hair gloss if you want shine and a tone refresh.
- Choose keratin if you wish for long-term frizz reduction and smoothness.
- You can even combine both (keratin first, gloss later) for the ultimate healthy shine.
Safety, Risks & Hair Health Considerations
Hair Gloss: Gentle & Safe
- Non-damaging and chemical light
- Ideal for fragile, color-treated, or thin hair
- Can be done frequently without risk
- Enhances tone and shine
Keratin Treatment: Effective but Requires Care
- This product is effective for frizz and smoothness, but should be applied by a trained stylist.
- Overuse can cause dryness, and professional timing is essential
- Only formaldehyde-free formulas are recommended
🧴 Tip: If your hair is overprocessed from bleach or color, start with a restorative gloss first. Once your hair feels stronger, move to a keratin treatment for long-term smoothness.
Tips for Healthy Hair After Treatment:
- Use sulfate-free shampoo
- Limit heat styling
- Hydrate regularly
- Schedule regular trims
- Consider follow-up gloss for extra shine

FAQ
Is hair gloss damaging?
No, hair gloss is gentle and designed to enhance shine and color without altering the natural structure of your hair. It works on the surface to smooth cuticles and improve overall hair appearance while leaving strands healthy and strong.
Can keratin remove color?
Keratin treatments don’t remove color, but applying it too soon after coloring can slightly alter pigment. It’s best to wait 5–7 days after coloring to ensure your shades remain vibrant.
How long does each treatment last?
Hair gloss typically lasts 4–6 weeks, giving your hair a refreshed shine and tone between color services. Keratin treatments are longer-lasting, usually 3–5 months, providing frizz control and smoothness over time.
Can I combine gloss and keratin?
Yes. Many clients enjoy both treatments for maximum shine and smoothness. Your stylist can apply gloss either before or after keratin to enhance color and reflective shine without compromising the keratin results.
Which treatment is better for fragile hair?
Hair gloss is generally safer for delicate, fragile, or overprocessed hair because it’s lightweight and non-altering. Keratin may be too heavy for delicate hair, so a stylist might recommend gloss first to strengthen strands before attempting keratin.
