The Best Solution for Frizzy Hair in Singapore: Cysteine® Shine Treatment at PRIX Salon

If you live in Singapore, you would know the challenge of managing hair in a warm, hot, and humid climate year-round. High humidity levels cause hair cuticles to open and swell, leading to persistent frizz, flyaways, and a flat appearance.

High humidity can cause hair to become porous, forming gaps in the outer cuticle layer. It can also reduce its ability to retain moisture, which commonly leads to dryness, frizz, and an increased risk of damage.

For many people, especially those with frequently dyed or chemically treated hair, daily styling becomes a tiring routine. Blow-drying, ironing, and layering on serums often provide only temporary control.

Fortunately, there is a proven solution that works beautifully in Singapore’s environment: Cysteine® Shine Treatment!

Why Cysteine® Shine Treatment Is a Game Changer

At PRIX Salon, our Cysteine® Shine Treatment is one of the top-performing in-house hair smoothening treatments. This service is designed specifically to combat frizz and deliver naturally smooth, glossy, manageable hair without relying on harsh straightening chemicals.

The treatment uses cysteine protein technology to reinforce the hair's internal structure. Cysteine is a natural amino acid that helps rebuild the essential disulfide bonds responsible for hair strength and elasticity. By smoothing and sealing the hair cuticle, the formula creates a protective barrier against moisture in the air. The result is hair that remains calm and controlled even in very humid conditions.

Most importantly, this technology is safe for a wide range of hair types, even for hair that has been bleached or coloured. That means you can enjoy trendy shades and fashionable colours while still choosing a smoothing treatment that keeps your hair healthy.

Here are the key ingredients, each playing an important part:

• Cysteine protein - rebuilds essential disulphide bonds and seals the cuticle for long-lasting frizz control

• Hyaluronic acid - provides moisture-binding properties that support lightweight hydration

• Ceramides - reinforce the natural protein matrix of the hair to improve strength and resilience

• Squalene - conditions hair with a light protective coating without heaviness

• Argan oil - adds gloss, smoothness and protection for frequently coloured hair

• Jojoba oil - deeply nourishes the hair surface and helps smooth the outer cuticle layer

• Shea butter - softens coarse or dry strands and enhances manageability

• Avocado oil - rich in vitamins and fatty acids to support elasticity and shine

And most importantly, what it is free from:

• No Parabens - may cause scalp irritation and sensitivity for some individuals

• No Sulfates - harsh cleansing agents that strip natural oils and moisture

• No Formaldehyde - a strong chemical often found in traditional keratin treatments that can weaken hair over time and produce an unnaturally flat, stiff finish

That is why Cysteine® Shine Treatment offers a safer, gentler, and more advanced smoothing solution for Singapore’s climate, delivering healthy volume, balanced hydration, and long-lasting natural shine.

The entire treatment typically takes about 2.5 hours, depending on hair thickness and length. Our stylist will first conduct a personalised 1-1 hair consultation to assess your current texture and condition. The smoothening lotion is then carefully applied section by section, followed by controlled heat to seal all the beneficial ingredients into the hair fibre.

Results from the Cysteine® Shine Treatment last 4 to 5 months, making it ideal for busy professionals, active students, and anyone who wants easy, everyday hair maintenance.

Frizzy hair is almost unavoidable in Singapore, but living with it is not your only option. Cysteine® Shine Treatment at PRIX Salon is a fuss-free solution that delivers smoother, glossier, healthier-looking hair.
