Overview

The Luxliss Keratin Smoothing Treatment 100ml is an at-home keratin service designed to calm frizz and make daily styling noticeably less of a battle. The compact bottle covers one full application on short to medium-length hair, or works for touch-up sessions between treatments. The process follows five structured steps that mirror what a salon technician would do — starting with a clarifying wash and finishing with a flat iron pass. That said, don't expect identical results across the board. Hair porosity, natural texture, and how closely you follow each step all influence the final outcome. It sits in a mid-range price bracket, making it accessible without feeling like a throwaway purchase.

Features & Benefits

This keratin treatment is built around a heat-activated formula — meaning a flat iron set between 150 and 190 degrees Celsius is not optional, it's essential. The heat bonds the formula to the hair shaft, which is where most of the smoothing actually happens. One thing that stands out is the flexibility around rinsing: you can wash it out the same day after a short wait, or leave it overnight for potentially stronger results. The formula claims natural ingredients, appealing to buyers cautious about harsh chemicals. As a liquid, it spreads evenly without clumping, making section-by-section application manageable even for a first-timer. It's designed to work within a broader Luxliss hair care routine, though it can be used on its own.

Best For

The Luxliss keratin kit is a practical fit for anyone dealing with persistently frizzy or curly hair who finds daily styling more exhausting than it should be. It also makes sense for people who have priced out salon keratin treatments and walked away sticker-shocked — this smoothing formula brings a similar approach into your bathroom at a fraction of that cost. That said, you need to be comfortable handling a flat iron and following a multi-step process. If you want something quick and low-effort, this probably isn't it. It works particularly well for short to medium hair, where the 100ml volume stretches further. First-timers not ready to commit to a larger kit will find this a reasonable way to test the waters.

User Feedback

Buyers who follow the application steps carefully tend to come away satisfied. Reduced frizz and noticeably softer hair are the most frequently mentioned wins, with some users reporting that their styling time dropped considerably in the weeks following treatment. The instructions are clear enough for a first-time home user, though the total time commitment — wash, apply, wait, iron — runs to a couple of hours. Where opinions diverge is on longevity and consistency. Fine or highly porous hair seems to hold results less reliably, and some reviewers felt the improvement faded sooner than expected. A few buyers also noted that skipping the companion products — particularly the recommended shampoo and mask — appeared to shorten how long the smoothing effect lasted.

Pros

  • Brings salon-style keratin smoothing home at a fraction of professional appointment costs.
  • Noticeably reduces frizz and improves daily manageability, especially in humid conditions.
  • Flexible rinse timing means you can wash same-day or the following morning.
  • The liquid consistency spreads evenly, making section-by-section application straightforward.
  • Compact 100ml size is ideal for short hair or a first-time keratin trial.
  • Natural material formulation appeals to buyers who prefer to avoid harsh chemical treatments.
  • Clear five-step instructions are accessible even for first-time home keratin users.
  • Many users report significantly reduced styling time in the weeks following treatment.
  • Works on a broad range of curly and unruly hair types when steps are followed carefully.

Cons

  • Total application time runs two hours or more, which is a real commitment on a busy day.
  • Results vary noticeably depending on hair porosity and texture — not a one-size-fits-all outcome.
  • A flat iron is non-negotiable; skipping the heat step means the formula will not bond properly.
  • The smoothing effect tends to fade faster when used without the companion Luxliss shampoo and mask.
  • Fine or highly porous hair types report shorter-lasting results compared to coarser textures.
  • At 100ml, the volume may fall short for long or thick hair needing full coverage.
  • Some buyers found results fell below expectations after their first application.
  • Requires purchasing additional Luxliss products to get the best long-term performance.
  • No detailed ingredient list is prominently available, which may concern ingredient-conscious buyers.

Ratings

The Luxliss Keratin Smoothing Treatment 100ml has been evaluated by our AI system after analyzing thousands of verified global buyer reviews, with spam, bot activity, and incentivized submissions actively filtered out to ensure an honest picture. Scores reflect both where this smoothing formula genuinely delivers and where real users ran into frustration — nothing is glossed over. The result is a transparent, balanced breakdown that helps you decide whether this treatment fits your hair type, lifestyle, and expectations before you buy.

Frizz Reduction
82%
18%
For buyers dealing with day-to-day frizz — especially in humid climates or during seasonal weather swings — this keratin treatment delivers a noticeably calmer, more manageable result when applied correctly. Users with thick, coarse curls consistently describe waking up to hair that no longer puffs up within minutes of stepping outside.
Results are far less consistent on fine or low-density hair, where frizz tends to return within a couple of weeks. A meaningful segment of users with mixed porosity hair reported that certain sections responded well while others showed almost no change.
Smoothing Effectiveness
78%
22%
When the full five-step process is followed carefully — including the flat iron pass at the correct temperature — most users see a genuine reduction in curl tightness and surface roughness. Several buyers noted it brought their hair closer to a blowout look with minimal daily effort after treatment.
The smoothing effect is heat-dependent, which means any shortcuts in the flat iron step produce noticeably weaker results. Users who expected results comparable to a professional salon treatment were often disappointed by how much variation exists in at-home outcomes.
Ease of Application
74%
26%
The liquid formula spreads without clumping, and the step-by-step instructions are written clearly enough that first-timers report being able to work through the process without confusion. Most buyers appreciated not needing any specialized tools beyond a standard flat iron they already owned.
The total time commitment — easily two to three hours from start to finish — caught many buyers off guard, particularly those who assumed it would be closer to a standard deep conditioning treatment. Some users also found the shower cap waiting period uncomfortable, especially in warm weather.
Result Longevity
63%
37%
Buyers who paired this smoothing formula with sulphate-free maintenance products, particularly the recommended Luxliss shampoo and conditioning mask, consistently reported results lasting four to six weeks before frizz started returning at the roots and ends.
Those who washed with standard sulphate shampoos or skipped the companion products found results fading noticeably within two to three weeks. Fine hair types in particular reported shorter-than-expected longevity, which undercuts the value proposition for buyers who need frequent reapplication.
Value for Money
76%
24%
Compared to a professional in-salon keratin service, this treatment represents a significant cost saving for buyers who are prepared to do the work themselves at home. For those who achieve strong results on the first or second application, the price-to-outcome ratio holds up well.
Buyers who need to purchase the companion shampoo and mask to maintain results find the total outlay creeps higher than expected. For anyone who sees limited results due to hair type, the cost feels harder to justify — especially if they need to repeat applications more frequently to chase the same smoothness.
Hair Softness
81%
19%
Improved softness is one of the most commonly cited outcomes across verified reviews, with buyers describing their hair as feeling noticeably silkier to the touch in the days and weeks following treatment. Many users noted that detangling became much easier, which reduced breakage during daily combing.
A subset of buyers with high-porosity or previously bleached hair reported that while softness improved initially, it was short-lived and not as dramatic as reviews from other hair types suggested. Overuse in tight succession led a small number of users to report a stiff or coated texture rather than genuine softness.
Hair Strengthening
67%
33%
Some users noted reduced breakage and a more resilient feel after consistent use, particularly those who had been dealing with heat-damaged or over-processed hair. The keratin component does appear to offer some structural reinforcement, at least in the short term.
Strengthening benefits are harder to quantify and less consistently reported than the smoothing effects. Several buyers felt the strengthening claims were overstated relative to their actual experience, especially after only one or two applications.
Packaging & Bottle Design
58%
42%
The compact bottle is easy to store and travels without taking up much room, which suits users who want to bring it on trips or store it in a small bathroom cabinet. The size communicates exactly what it is — a single-use or limited-use treatment rather than a bulk product.
A recurring complaint is that the applicator design makes it difficult to dispense a controlled amount, leading to product waste or uneven application on the first use. Several buyers also noted that the bottle gives no indication of how much product remains, making it hard to gauge when to order a replacement.
Scent
61%
39%
A portion of users found the scent mild and inoffensive during application, noting it did not linger on the hair after rinsing. For those sensitive to strong fragrances, the relatively neutral profile of this smoothing formula was considered a plus.
Some buyers described the scent during the flat iron step as noticeably chemical, which was particularly uncomfortable in smaller bathrooms with limited ventilation. A handful of users specifically mentioned that the smell made the processing period unpleasant despite the end result being satisfactory.
Ingredient Transparency
54%
46%
The brand positions the formula as containing natural ingredients, which resonates with buyers who are trying to move away from heavily synthetic treatments. For this segment, even a general natural positioning is enough to feel more comfortable choosing this treatment over chemical alternatives.
The absence of a fully detailed, publicly accessible ingredient list is a real frustration for ingredient-conscious buyers who want to verify exactly what they are applying near their scalp. Several reviewers noted they could not find a complete INCI list on the packaging or any official brand channel.
Instructions Clarity
77%
23%
First-time users generally found the five-step guidance clear and logical, which reduced the anxiety of attempting a keratin treatment without professional help. The inclusion of specific temperature ranges for the flat iron step was flagged as particularly useful by multiple buyers.
A few users felt the instructions lacked guidance on how to adapt the process for different hair lengths or densities, leaving thicker-haired buyers guessing about product quantity and timing. Some international buyers also noted that translated instructions were harder to follow precisely.
Compatibility with Hair Types
66%
34%
The treatment performs most reliably on medium-density, naturally curly hair — the hair type it is explicitly formulated for. Buyers in this category tend to report the most consistent, predictable results across multiple applications.
Results on fine, highly porous, bleached, or extremely coarse hair types are significantly more unpredictable. Users outside the target hair profile often found themselves part of the mixed-review segment, where results ranged from mildly effective to virtually unnoticeable.
Heat Damage Risk
59%
41%
When used within the prescribed temperature range, the majority of buyers did not report additional heat damage beyond their normal flat iron routine. For users already comfortable with regular heat styling, the added flat iron step in the process did not feel unusually risky.
For buyers who rarely use heat tools or have fragile, fine hair, the mandatory flat iron requirement introduces a non-trivial risk of damage if temperatures are misjudged or sections are passed over too slowly. A small number of users reported increased dryness or brittleness after treatment, likely from improper heat application.

Suitable for:

The Luxliss Keratin Smoothing Treatment 100ml is a solid pick for anyone with curly, frizzy, or thick hair who has grown tired of spending an hour fighting with a blow dryer every morning. It works best for people who are comfortable dedicating a couple of hours to a structured at-home treatment process — think of it less like applying a hair mask and more like running a mini salon appointment in your bathroom. The compact 100ml volume is especially practical for those with short or medium-length hair, or for someone who wants to trial a keratin treatment before investing in a larger, pricier option. Budget-conscious buyers who have looked at professional keratin services and found them out of reach will find this smoothing formula hits a reasonable middle ground between drugstore conditioning treatments and salon-grade procedures. It also suits anyone already using or open to building a Luxliss hair care routine, since the supporting shampoo and conditioning mask genuinely help extend how long the results hold.

Not suitable for:

The Luxliss Keratin Smoothing Treatment 100ml is not the right fit for buyers expecting a quick, low-effort solution — this is a five-step process that requires a clarifying wash, a 45-minute wait under a shower cap, and a flat iron pass at temperatures between 150 and 190 degrees Celsius, none of which is optional. Anyone without a reliable flat iron, or who is uncomfortable using one, should look elsewhere. People with very fine or highly porous hair may also find the results inconsistent or shorter-lived than expected, based on how this type of hair typically responds to keratin treatments. If you are hoping to avoid heat styling altogether, this smoothing formula simply will not deliver its intended effect without it. It is also worth noting that the 100ml size is unlikely to provide full coverage on long or very thick hair, making it impractical for buyers with higher volume needs.

FAQ

A flat iron is essential, not optional. The formula is heat-activated, which means passing a flat iron set between 150 and 190 degrees Celsius through each section is what actually bonds the treatment to the hair shaft. Skipping this step will give you little to no smoothing effect.

Realistically, you should set aside around two to three hours for the full process. That includes a double cleansing wash, drying, applying the treatment, sitting with the shower cap on for 45 minutes, blow drying again, and then going through each section with the flat iron. It is a genuine time commitment, so plan accordingly.

For short to medium-length hair, 100ml should comfortably cover one full application. If your hair is long or particularly thick, you may find the volume runs short before you reach full coverage. In that case, it is worth picking up two bottles to avoid running out mid-application.

You have the option to rinse the same day — just wait 5 to 10 minutes after completing the flat iron step, then rinse with plain water. That said, leaving it overnight and washing the next morning tends to give stronger, longer-lasting results, so if your schedule allows it, waiting is worth it.

Keratin treatments can generally be used on color-treated hair, but chemically processed or bleached hair tends to be more porous, which can affect how evenly the formula absorbs and how long the results hold. If your hair has significant chemical damage, results may be less predictable, and it is a good idea to do a small patch test first.

Most users see results lasting anywhere from three to six weeks, though this depends heavily on hair type, porosity, and how the hair is maintained afterward. Using sulphate-free shampoo and the recommended Luxliss conditioning products after treatment helps extend the results noticeably.

You can technically use any shampoo, but sulphate-heavy formulas will strip the treatment out faster. The brand recommends using their own keratin shampoo and conditioning mask for maintenance, and based on user feedback, those who stick to compatible products do report longer-lasting smoothness.

Yes, this treatment is designed for at-home use and comes with step-by-step instructions that are clear enough for a first-timer to follow. The main things to be careful about are ensuring proper ventilation when using the flat iron and not applying heat higher than the recommended range, which could cause damage.

This smoothing formula is primarily formulated for curly hair types, but people with fine, straight hair dealing with frizz can still see results. That said, fine hair tends to be more porous and can sometimes respond less predictably to keratin treatments, so temper expectations and consider a single application before committing to regular use.

Most keratin treatments are intended to be repeated every four to eight weeks as results fade, though this varies by individual hair type. Applying too frequently on already-treated hair is generally not recommended, as repeated heat and product application can lead to buildup or dryness over time. Waiting until you notice frizz returning before reapplying is a reasonable rule of thumb.
