Silk-Smooth Control with Lasting Shine

Professional Keratin Latino is an advanced smoothing treatment designed to reduce frizz, soften texture and enhance shine. It works by infusing the hair with keratin proteins that help strengthen and smooth the outer layer.
The formula penetrates the hair fibre, filling in porous areas and sealing the cuticle using controlled heat. This creates a humidity-resistant shield that keeps hair sleek and manageable for months.
If you’re tired of daily straightening or battling frizz, this treatment delivers effortless smoothness and mirror-like shine leaving you polished, refined and beautifully in control.

Our Step-by-Step Process

How the Latino Keratin Treatment Works

Knowing what to expect before a keratin treatment makes all the difference. A professional Latino Keratin at Pierre Haddad is a structured, four-stage process carried out by experienced specialists in our Sydney CBD salon.

Depending on hair length and density, appointments typically take between 1.5 and 4 hours.

Step 1 — Deep Cleanse and Preparation

(15–20 minutes)

Your hair is washed with a clarifying shampoo to remove product buildup, excess oil and any residue that could interfere with absorption. This opens the cuticle and ensures the keratin formula penetrates evenly from root to tip. No conditioner is used at this stage.

Step 2 — Latino Keratin Formula Application

(20–40 minutes)

The Professional Latino Keratin formula is a formaldehyde-free smoothing complex enriched with keratin proteins. It is applied section by section through clean, towel-dried hair.

The formula is worked through each strand to fully saturate them, then left to process for 20–30 minutes. This is where frizz control and cuticle smoothing begin at a structural level.

Step 3 — Heat Sealing with a Flat Iron

(30–60 minutes depending on length)

Your stylist uses a professional flat iron to seal the keratin deep into the hair shaft. The controlled heat activates the proteins, locking them into the cortex and forming a humidity-resistant barrier around each strand. This step is what gives the treatment its lasting smoothness and mirror-like shine.

Step 4 — Blow-Dry, Finishing and Reveal

(20–30 minutes)

The hair is blow-dried and finished to reveal the full result: sleek, frizz-free, brilliantly smooth hair.

Your stylist will walk you through your personalised aftercare instructions before you leave, including the 72-hour wash window and the right products to maintain your results at home.

Note: Pierre Haddad Hair uses only formaldehyde-free keratin formulas; a safer choice for both clients and our team, without compromising on results.

Safety & Transparency

Is the Latino Keratin Treatment Formaldehyde-Free?

This is one of the most common questions we get — and it's the right one to ask. Some keratin treatments on the market use formaldehyde-releasing agents, which is a concern for both clients and stylists.

At Pierre Haddad Hair, we use professional-grade, low-formaldehyde or formaldehyde-free keratin formulas sourced from trusted professional suppliers. Our priority is a treatment that delivers the results you want without compromising your health or the health of our team.

During your consultation, your stylist will discuss the exact formula being used and answer any specific health questions you may have. We believe transparency here is non-negotiable — you should know exactly what's going into your hair before any treatment begins.

Tip: Always ask your salon about the keratin formula used. If they can't tell you, that's a red flag. At Pierre Haddad, we can.

The Process

How the Latino Keratin Treatment Works

The full treatment typically takes 2–3 hours depending on hair length and density. Here's what happens at each stage.

1

Consultation

Your stylist assesses your hair type, texture and condition to determine the correct formula strength and application approach.

2

Clarifying Wash

A deep cleanse removes product build-up and opens the cuticle to allow maximum keratin penetration.

3

Keratin Application

The Latino Keratin formula is applied section by section through towel-dried hair and left to absorb for 20–30 minutes.

4

Blow-Dry & Sealing

The hair is blow-dried smooth, then sealed with a flat iron at a controlled temperature to lock the treatment into the hair shaft.

5

Final Finish

Your stylist finishes with a final smooth blow-dry, revealing the full mirror-like result. You leave the salon with immediately sleek, frizz-free hair.

Compare Treatments

Latino Keratin vs. Nanoplasty vs. Japanese Straightening

Not sure which smoothing treatment is right for you? Here's the key difference between our three most popular services.

Treatment	Result	Duration	Permanent?	Best For
Latino Keratin	Frizz reduction, mirror shine	3–4 months	No	All frizz-prone hair types
Nanoplasty	Frizz reduction + deep reconstruction	4–8 months	No	Porous or chemically treated hair
Japanese Straightening	Permanently glass-straight	Permanent (new growth only)	Yes	Very curly or resistant hair

How to Maintain Your Keratin Treatment at Home

The right aftercare routine makes the difference between results that last 3 months and results that last 5. With over 20 years of experience administering keratin treatments in Sydney CBD, our team has refined the following guidance for every client.

Do not wash your hair for 72 hours after treatment. This is the most critical window. Water disrupts the keratin bonding process while it's still setting. Avoid rain, sweat and steam as well.
Switch permanently to a sulphate- and sodium chloride-free shampoo. Sulphates and sodium chloride are the two fastest ways to break down keratin results. Pierre Haddad's own sulphate-free shampoo range is formulated specifically for treated hair and is available online and in-salon.
Avoid salt water and chlorine for the first 3 days. Ocean swimming and pool sessions accelerate keratin breakdown. After the initial 72 hours, always rinse hair thoroughly with fresh water before and after any exposure to salt or chlorine.
Minimise heat styling. Your hair is already smooth; you won't need the flat iron as often. When you do style with heat, use a heat protectant and keep temperatures moderate. Excessive heat over time will shorten your results.
Schedule your reapplication around 3 months. As your natural hair grows out and the treated lengths gradually revert, a timely reapplication keeps your result seamless. Most clients at our Sydney CBD salon rebook every 12–16 weeks.

Bonus note for coloured hair clients:

If you've had highlights, balayage or colour before your keratin treatment, or are planning colour afterwards, let your stylist know at the time of booking.

Latino Keratin is safe for colour-treated hair and can actually enhance shine and vibrancy post-colour, but the sequence and timing of services matter.

We recommend a minimum 2-week gap between chemical colour and keratin application.
