Smoothing Treatment Aftercare:
How to Make Keratin, Nanoplasty and Hair Botox Last Longer
Your treatment is only half the result. What you do in the first 72 hours, and the shampoo you buy afterwards, decides the other half.
Protect the Result
Aftercare in Practice
The difference between getting eight weeks out of a keratin treatment and getting a full three months is almost never the treatment. It is the shampoo. Aftercare is the half of the equation clients control entirely, and it is the half most people are never properly briefed on before they leave the salon.

The First 72 Hours: The Critical Window
Smoothing treatments are not finished when you leave the salon. The formula continues setting into the hair structure for up to three days, and almost every aftercare rule in the first stretch exists to protect that process.
Do Not Wash It
Up to 72 hours for keratin and nanoplasty. Water interrupts the formula before it has fully bonded. Your stylist will confirm the exact window.
No Ties, Clips or Buns
Anything that bends the hair can set a kink into it permanently at this stage. Wear it down and loose.
No Tucking Behind Ears
The same reason. A crease behind the ear on day one can still be there on day thirty.
Sleep Carefully
Loose and flat. A silk or satin pillowcase helps, and no sleeping on damp hair.
Skip the Gym Sweat
Heavy sweating at the scalp acts like washing. Push the intense sessions out a couple of days if you can.
No Colour Yet
Colour and smoothing need to be spaced. Generally at least two weeks after keratin.
If you take one thing away: the 72-hour window costs you three days of inconvenience and buys you months of result. It is the highest-return rule in the whole guide.
Products to Use vs Avoid
This is where most treatments quietly die. Sulphates are detergents, and they strip a smoothing treatment considerably faster than they strip dirt.
| Use | Avoid | |
|---|---|---|
| Shampoo | ✓ Sulphate-free, sodium chloride-free | ✗ Sulphates, clarifying, anti-dandruff |
| Conditioner | Sulphate-free, mid-lengths to ends | Heavy silicone build-up formulas |
| Weekly | A nourishing mask or gloss | ✗ Deep-cleansing detox masks |
| Styling | Heat protectant, lightweight serum | Products with drying alcohols |
| Dry shampoo | Sparingly, at the roots only | Daily use — it builds up fast |
| Water | Fresh water rinse after swimming | ✗ Leaving chlorine or salt in |
Read the back of the bottle rather than the front. “Keratin-safe” on the label means nothing legally; the ingredient list showing no sodium lauryl sulphate, no sodium laureth sulphate and no sodium chloride means everything.
Heat Styling Rules Post-Treatment
The pleasant surprise of a good smoothing treatment is how little heat you need afterwards. Hair that dries close to straight on its own does not need twenty minutes with a straightener, and every session you skip extends the result.
When you do use heat: always a protectant first, a moderate temperature rather than the maximum setting, and one pass per section rather than three. Repeatedly ironing the same section at high heat is what degrades a treatment fastest.
In the first week, ease off entirely if you can. After that, normal styling is fine within those limits.
In the Salon
Before & After
Hair that still looks like this three months later is almost always hair that was looked after properly in the first three days.
Results shown are from services performed at Pierre Haddad Hair Management, Sydney CBD. Individual results vary with hair type, condition and aftercare.
Swimming, Gym and Everyday Life
None of this means changing your life. It means a couple of small habits.
Before You Swim
Wet your hair with fresh water first. Hair that is already saturated absorbs far less chlorine or salt.
After You Swim
Rinse thoroughly with fresh water as soon as you can, then condition. This is the single biggest lifestyle factor.
At the Gym
Sweat at the scalp is salty water. Rinse rather than full-wash after heavy sessions where you can.
In the Sun
UV degrades smoothing treatments the same way it fades colour. A hat on long beach days is genuinely useful.
What We Recommend From the Shop
You do not have to buy from us, but you do have to buy sulphate-free. These are the ones we use and stock, with what each is actually for.
Keratin Infused Shampoo 500ml — $45
The everyday sulphate-free wash for smoothed and coloured hair. This is the core purchase after any keratin or nanoplasty treatment.
Keratin Infused Conditioner 400ml — $38
Pairs with the shampoo. Mid-lengths to ends only, and keep it off the scalp.
Snaplex Step 3 — $25
At-home bond maintenance. Useful for hair that has been through both colour and smoothing.
Charcoal Revitalising Treatment 250ml — $45
The weekly step if your scalp gets congested, or if you live somewhere with hard water.
Silicone Shampoo Brush — $19.50
Cleans the scalp properly without needing a harsher shampoo to do it.
Charcoal Revitalising Shampoo 500ml — $45
The alternative sulphate-free wash if build-up rather than dryness is your issue.
Treatment-by-Treatment Differences
The rules above cover all three. These are the places they diverge.
| Keratin | Nanoplasty | Hair Botox | |
|---|---|---|---|
| Wash window | ✓ Up to 72 hours | ✓ 48–72 hours | No strict window |
| Ties and clips | Avoid for 72 hours | Avoid for 48 hours | Normal almost immediately |
| Sulphate-free | ✓ Essential | ✓ Essential | ✓ Recommended |
| Colour spacing | At least 2 weeks after | Ask your stylist | Minimal restriction |
| Booster to extend | Gloss at ~6 weeks | Gloss at ~3 months | Repeat every 3–4 weeks |
| Typical longevity | Around 3 months | 4–8 months | 3–4 weeks |
