What is hair botox?

Quick answer: Hair botox is a professional deep repair treatment that restores softness, shine and health to the hair fibre. Despite the name, it contains no injectable botox – the term refers to a rejuvenating treatment that deeply saturates the hair with proteins, collagen and nourishing oils, repairing damage from the cortex outward. Results last up to 3 months.
Over time, brushing, heat styling, colouring and sun exposure accelerate the ageing of the hair, leaving it dry, dull and fragile. Royal Hair Botox works by penetrating deep into the hair structure – down to the cortex – to fill in broken or empty areas of the fibre, seal split ends and restore elasticity.
Unlike a traditional conditioning mask that coats the surface, hair botox delivers a more intensive and longer-lasting repair. Think of it as a facelift for your hair – erasing visible damage caused by daily stress and lifestyle, and helping your hair feel younger, softer and more alive.
Hair botox is the right treatment if your hair fits any of the descriptions below – and especially if Sydney’s humidity, beach lifestyle or colour history is a factor in your hair’s condition.
Hair condition:
Lifestyle triggers:
Royal Hair Botox is suitable for all hair types – coloured or bleached, curly or straight, chemically treated or virgin. A professional consultation is included so we tailor the treatment to your exact hair history and condition.

Sydney’s environment puts specific demands on hair. Mention these to your stylist before your treatment so the formula and aftercare plan can be tailored properly.
Beach & chlorine
Salt water and pool exposure dry hair fast and shorten how long results last. If you swim weekly – ocean or pool – we build a protective aftercare routine into your appointment so results hold for longer.
Colour history
Bleach and highlights change hair porosity significantly. Tell us exactly what colour services you have had in the last 12 months so we calibrate the treatment seal and finish to your hair’s specific porosity level.
After your Royal Hair Botox treatment at Franck Provost Sydney you will notice changes immediately and progressively over the following days.

How long does hair botox last?
Results last up to 3 months, depending on your hair type, how often you wash, and lifestyle factors such as swimming frequency. Using a sulphate and sodium free shampoo and following your stylist’s aftercare advice significantly extends results.

The Royal Hair Botox formula used at Franck Provost is a professional-grade blend that works at the cortex level – not just on the surface. Key active ingredients include:
This combination deeply nourishes, strengthens and hydrates the hair fibre – supporting more resilient, healthier hair with each treatment. The collagen component improves strength and elasticity; the amino acids reinforce the hair’s internal structure. Both have a cumulative benefit with repeated treatments.
This is one of the most frequently asked questions in our Sydney salons.
The short answer: both Hair Botox and Keratin / Nanoplasty treatments work within the hair fibre and provide deep repair.
The main difference is how they interact with the hair and the result they deliver.
Hair Botox: Deep repair + fibre restoration
Hair Botox is an intensive repairing treatment designed to restore and strengthen hair that has been weakened over time.
This can be caused by heat styling, chlorine, sea salt, colouring, chemical services or everyday wear and tear.
It works by saturating the hair fibre with amino acids, collagen and proteins, helping to rebuild, hydrate and improve the overall quality of the hair.
Result: softer, fuller, shinier hair with improved elasticity and a healthier feel.
Frizz control: very light (not the main goal)
Straightening: no
Best for: dry, damaged, dull or weakened hair, including over-processed hair
Keratin / Nanoplasty: Repair + smoothing + frizz control
Keratin / Nanoplasty treatments also work within the hair fibre to repair and strengthen the hair, while additionally smoothing the cuticle and reshaping the hair structure.
Result: smoother, more controlled, shinier hair with reduced volume and easier styling.
Frizz control: yes
Straightening: moderate to strong (depending on the hair type)
Best for: clients wanting repair + smoother, more manageable hair
In short:
If your hair feels dry, damaged or weakened and your priority is to restore its health → Hair Botox is the perfect treatment.
If you want to repair your hair while also reducing frizz and making it smoother and easier to manage → Keratin / Nanoplasty is the better option.
If you want a stronger smoothing or straighter outcome that lasts longer, nanoplasty may be a better fit. Read the nanoplasty treatment guide
Short answer: If your hair feels dry, dull, damaged or hard to manage – yes. Hair botox delivers noticeable improvement in softness, shine and manageability within a single session, with results lasting up to 3 months. Most clients find their daily styling routine becomes significantly faster and easier.
It is a professional-only treatment performed in-salon, which means the formula and technique are calibrated to your specific hair – something at-home products cannot replicate. The collagen and amino acid complex works at the cortex level to deliver genuine structural repair, not just surface conditioning.
Many clients choose hair botox in Sydney after summer or following colour damage to restore hydration and softness. It is also popular as a regular maintenance treatment every 3 months to keep hair in its healthiest state year-round.

What you do after your Hair Botox treatment plays a key role in how long your results last.
Your stylist will always guide you with a personalised routine, but here are the essentials to keep your hair looking its best.
Unlike some smoothing treatments, Hair Botox does not require a waiting period.
You can:
The treatment works within the hair fibre (cortex) and is fully sealed during the service, so your results won’t be affected.
To maintain your Hair Botox results, it is essential to use a sulphate-free and sodium chloride-free shampoo.
These ingredients can strip the treatment from the hair and significantly reduce its longevity.
Your stylist will recommend the Royal Hair Botox range, specifically designed to maintain hydration, shine and softness for as long as possible.
This is the key point most clients don’t know 👇
Hair Botox works by saturating the hair fibre with proteins, amino acids and collagen.
Using additional protein-based products can overload the hair.
Avoid products containing:
Overloading the hair can make it feel heavy or even lead to damage over time.
Sea salt and chlorine can reduce the lifespan of your treatment.
To protect your hair:
Hair Botox is a repairing treatment that can be repeated as needed.
For best results, we usually recommend refreshing it every 2 to 3 months, depending on your hair type and lifestyle.
What is hair botox?
Hair botox is a professional deep repair treatment that restores health, softness and shine to the hair fibre. Despite the name, it contains no injectable botox – the term refers to a rejuvenating “facelift” for the hair. It works by saturating the fibre with proteins, collagen and nourishing oils, repairing damage from the cortex outward. It is suitable for all hair types and all hair colours.
How long does hair botox last?
Results typically last up to 3 months, depending on your hair type, wash frequency and lifestyle. Using sulphate-free shampoo and protecting your hair from salt and chlorine will extend results. Your stylist will advise on the routine most relevant to your lifestyle at your appointment.
Can I get hair botox on coloured or bleached hair?
Yes – hair botox is suitable for coloured, bleached and chemically treated hair. Bleaching and highlighting change hair porosity, so we tailor the treatment seal and finish to your colour history for best results. Tell your stylist exactly what colour services you have had in the last 12 months before your appointment.
Can I get hair botox if I swim regularly?
Yes. Salt and chlorine exposure can dry hair quickly and shorten how long your results last. Tell your stylist how often you swim – ocean or pool – and we will tailor both the treatment and your aftercare routine to protect results for longer.
Does hair botox straighten the hair?
No. Hair botox improves texture but does not straighten hair. It enhances your natural hair pattern while making it smoother and more manageable. If a straighter result is your goal, keratin treatment or nanoplasty may be more suitable – ask at your free consultation.
Which Sydney salon should I choose?
Most of the Franck Provost Sydney salons offer the same Royal Hair Botox treatment and level of service. Choose based on location convenience: For Northern Subburbs, book in Macquarie Centre, you’ll find us in Chatswood or Crows Nest for North Shore and the CBD salon for city appointments. Check availability at each salon online and book whichever has the earliest opening that suits you.
