What is the Diamond Sleek Shine-Coat Spray?
The Garnier Fructis Diamond Sleek Shine-Coat Smoothing Spray is a revolutionary, heat-activated styling treatment designed to transform damaged strands into sleek, frizz-free perfection. Rather than relying on heavy styling creams that can weigh hair down, this lightweight mist creates an invisible shield around the hair shaft. Infused with vegan keratin and smoothing polymers, the 100% vegan formula is designed to work in tandem with your hot tools. It effectively seals the cuticle to lock out environmental moisture, making daily management easier while leaving no heavy or greasy residue behind.
Top Benefits of the Smoothing Spray
When you properly activate the Diamond Sleek formula with heat, you unlock a rigorous set of clinically-tested benefits that upgrade your entire look:
- Intense, Reflective Shine: The formula perfectly aligns the cuticle scales, providing up to 100 hours of frizz-free, diamond-like shine.
- Unmatched Smoothness: Hair treated with the smoothing spray is proven to be 3X smoother compared to using a non-conditioning shampoo.
- Maximum Heat Protection: It safely defends your hair against the extreme temperatures of blow-dryers and flat irons, providing heat protection up to 450°F.
Heat Activation: The Secret to Ultra-Sleek Hair
To maximize the smoothing benefits of keratin-infused formulas, they are often paired with heat styling. When you apply a smoothing spray and follow it with the tension of a blow-dryer or flat iron, the heat helps to perfectly align the cuticle scales and lock the ingredients into place.
For example, the Garnier Fructis Diamond Sleek Shine-Coat Smoothing Spray utilizes an innovative 8% Vegan Keratin Smoothing Complex paired with sustainably sourced Moroccan Argan Oil. When activated by heat, this specific formula forms an invisible, water-resistant shield around the hair. This product-specific technology delivers up to 100 hours of frizz-free sleek, diamond-like shine and protects your strands against heat damage up to 450°F.
Step-by-Step: How to Use Diamond Sleek
To achieve the ultimate flawless, diamond-sleek finish, the spray must be applied and activated correctly. Follow this simple routine:
Step 1: Cleanse and Condition
Start by washing your hair with a smoothing system, like the Garnier Fructis Sleek & Shine Shampoo and Conditioner, to gently cleanse and detangle.
Step 2: Apply to Damp Hair
Gently towel-dry your hair. Generously mist the Diamond Sleek Shine-Coat Smoothing Spray evenly throughout your clean, damp hair, ensuring you coat every section from mid-lengths to ends.
Step 3: Blow-Dry with Tension
This is the most crucial step! Using a round or paddle brush, blow-dry your hair while pulling it taut. The tension from the brush combined with the heat of the blow-dryer is what activates the formula’s protective polymers.
Step 4: Flat Iron (Optional)
For an even more intense, diamond-like shine, finish your look by passing a flat iron over your completely dry hair. This extra burst of heat perfectly aligns the cuticle scales for maximum light reflection.

How to Use Diamon Sleek Smoothing Spray FAQs
Can I let my hair air-dry after applying the Diamond Sleek spray?
No, air-drying will not provide the intended results. The Garnier Fructis Diamond Sleek Shine-Coat Smoothing Spray is a heat-activated formula. To achieve up to 100 hours of diamond-like shine and effectively block out humidity, you must blow-dry your hair using tension with a brush.
Will the Shine-Coat Smoothing Spray weigh my hair down?
Not at all! Unlike heavy styling creams, waxes, or thick oils, this spray is formulated to be entirely weightless. Once activated by heat, the 100% vegan formula creates an invisible shield that leaves no heavy, sticky, or greasy residue behind—just soft, touchable, and sleek hair.
Do I need to reapply the Diamond Sleek spray every day?
No, you do not need to reapply the spray daily. Because the heat-activated formula creates a durable, water-resistant shield, you only need to generously mist it onto clean, damp hair on your wash days right before blow-drying to lock in your diamond-like shine for days.
Can I use other styling products with the smoothing spray?
Yes, but application order matters. For the best results, the Garnier Fructis Diamond Sleek Shine-Coat Smoothing Spray should be the final product applied to your damp hair before you begin heat styling. If you use a leave-in conditioner, apply it first, then mist the smoothing spray over the top so its heat-activated polymers can effectively coat and seal the outermost layer of your hair.
Is the Diamond Sleek smoothing spray suitable for curly or wavy hair?
Absolutely! Whether your hair is naturally straight, wavy, or curly, the smoothing spray is designed to combat frizz and deliver a sleek finish. Just keep in mind that the formula must be activated with the tension of a brush and the heat of a blow-dryer to properly align the cuticle and achieve that flawless, straight, diamond-like shine.
