Quick answer: Hair straightening in Hanoi is not one service. Permanent straightening changes the treated section until it grows out; keratin is usually chosen to reduce frizz and make styling easier; Steam ION is a separate menu option whose exact finish should be agreed during consultation. At Nhat Tam Hair Salon, English support is available on request. Send current-hair photographs and your chemical history before booking, then confirm the product system, total price and realistic finish before the service starts.
If your reference photograph shows glass-straight hair, the most important question is not “Which treatment is strongest?” It is “Which result can my hair safely hold?” Fine highlighted hair, resistant virgin hair and lengths that have already been permed need different plans. This guide helps international visitors compare straightening, keratin and Steam ION before booking in Hanoi.
Compare three smoothing and straightening routes
| Option | Main goal | What to ask | Maintenance decision |
|---|---|---|---|
| Permanent straightening | A straighter treated section with a clear change in texture | Can my previous colour, bleach or perm history tolerate the process? | How will new regrowth be handled without overlapping old lengths? |
| Keratin smoothing | Less frizz and easier blow-drying rather than a permanent texture change | How straight should I expect my own pattern to look after washing? | Which aftercare applies to the exact product used? |
| Steam ION menu option | A salon smoothing route that must be matched to the target finish | Which product system and steps will be used on my appointment? | When should the result be reviewed and what home routine is recommended? |
The names above describe service directions, not guarantees. Product systems differ, and the same service name can produce different finishes on different starting points. Ask the stylist to describe the expected result on your hair after the first home wash, not only immediately after the salon blow-dry.
Permanent straightening: who should consider it?
Permanent straightening is the strongest commitment of the three. The treated section does not return to its original pattern simply because time passes; the visible contrast appears as natural hair grows from the roots. That makes the regrowth plan part of the first consultation.
Bring a full chemical history covering bleach, colour, box dye, perm, relaxing, keratin and previous straightening still present in the lengths. If sections have different histories, the stylist may need different timing or may recommend a less aggressive goal. A strand test can reduce uncertainty, but it cannot promise that every part of the head will behave identically.
Questions to settle before permanent straightening
- Which sections are untreated and which have previous chemical work?
- Is the target pin-straight, softly straight or simply easier to style?
- Where will the product stop to avoid overlapping treated lengths?
- What is the plan if the strand test shows too much weakness?
- When can colour or bleach safely be discussed again?
Keratin smoothing: reduce frizz without confusing it with rebonding
Keratin is often requested by travellers whose hair becomes harder to manage in Hanoi humidity. The useful goal is usually reduced frizz, faster drying and a smoother finish. It should not be sold as identical to permanent straightening. Natural wave or curl can remain, especially after washing and air-drying.
Ask to see the product label and the instructions that apply to that system. Confirm when you can first wash the hair, whether clips or tight ties should be avoided, and which shampoo is recommended. Do not borrow rules from a different brand or from a social-media video.
Steam ION: define the result before choosing the menu name
Steam ION appears as its own option on the current Nhat Tam service menu. A menu name alone does not tell an international visitor how straight the result will look or how it differs from the other systems on their hair. Use the consultation to agree on the desired movement, volume and finish, then ask the stylist to name the product and steps planned for the appointment.
If preserving some natural movement matters, say so explicitly. If your priority is a flat, straight finish, say that too. A photograph of what you do not want is often as helpful as the reference you like.
What must be checked before any chemical service?
- Current condition: elasticity, breakage, dry ends and uneven porosity.
- Chemical history: all colour, bleach, perm, smoothing and home treatments still in the hair.
- Scalp condition: postpone the service if the scalp is sore, broken or actively irritated.
- Target finish: pin-straight, softly straight, reduced frizz or easier blow-drying.
- Fallback plan: what happens if the requested result is not suitable today.
If the lengths feel fragile after bleach or repeated colour, start with the damaged hair treatment guide. For a broader description of strand thickness, density, pattern and porosity, use the hair-type consultation guide. If you are weighing a colour service alongside straightening, our guide to hair porosity and color results in Hanoi covers how porosity changes what a colour can do.
Published price ranges and timing
The current Nhat Tam price menu lists a basic cut-plus-chemical combo, including straightening options, from 480,000 to 780,000 VND after the stated booking and check-in offer, depending on length. Standard keratin is listed from 900,000 to 1,350,000 VND, while the Steam ION and vegan combo is listed at 900,000 VND. Prices and eligibility can change, so confirm the final VND quote, inclusions and estimated chair time before product is mixed.
Do not schedule a chemical straightening service immediately before a flight, wedding or important meeting. Leave enough time for assessment and for the plan to change if the hair is unsuitable. Nhat Tam publishes a 90-day warranty for perm and straightening; ask the team to explain what is covered for the exact service you choose.

Frequently asked questions
Is keratin the same as permanent hair straightening?
No. Keratin is generally selected to reduce frizz and make styling easier, while permanent straightening changes the treated section more decisively. The expected finish depends on the product system and your starting hair.
Can bleached hair be straightened?
It requires an in-person assessment and may be unsuitable. Send the bleach history and photographs before booking. If elasticity or breakage is poor, a safer plan may be to wait or choose a lower-commitment goal.
Will straightened hair stay straight in Hanoi humidity?
The treated section may remain straighter, but humidity still affects surface frizz, regrowth and styling. Ask what result to expect after washing and air-drying, not only after the salon finish.
How long should I allow for the appointment?
Timing depends on length, density, condition, product and the number of processing sections. Reserve a generous block and confirm the estimate after the stylist reviews your photographs.
Does Nhat Tam offer English support?
English support is available on request. Add the request when using the online booking form and send your hair history in advance for chemical services.
