Effectiveness of Straightening
89%
Many users note that this keratin treatment provides excellent straightening results, even on thick or coarse hair. After using it, hair feels smoother, more manageable, and much easier to style. The long-lasting results, lasting between 3-6 months, are a major highlight, saving time and effort with fewer touch-ups needed.
Some users feel that while the treatment straightens well initially, the effects may gradually fade, especially in humid or rainy conditions. Additionally, those with particularly stubborn curls or very thick hair have mentioned needing multiple applications to achieve the desired level of straightness.
Frizz Reduction
91%
The frizz-reducing benefits of this product stand out in user feedback. Customers report noticeable improvements in hair texture, with smoother, frizz-free hair even in challenging weather conditions. It's especially effective in controlling flyaways and giving hair a polished, shiny appearance.
However, a few users with very frizzy or damaged hair expressed that the frizz reduction wasn't as dramatic as they had hoped. Some mentioned that they had to use additional products for the best results, especially for managing hair during humid days.
Long-Lasting Results
86%
Many buyers appreciate the longevity of the results, with some users confirming that their hair remains smooth and frizz-free for 3-6 months, as advertised. This makes the treatment great for those looking for a low-maintenance, long-term solution to frizzy or unruly hair.
Not all users experience the promised 3-6 month results. A few customers reported that the effects began to wear off sooner than expected, especially for those who regularly use styling tools or have extremely textured hair. Application technique also plays a role in how long the results last.
Ease of Use
78%
22%
Several users mention that while the treatment itself is effective, it’s relatively straightforward to apply once you get the hang of it. The included clarifying shampoo helps prepare the hair, making the treatment process smoother for first-time users. Many find it convenient for at-home use compared to salon treatments.
A common drawback noted by users is the time-consuming nature of the application. With a process that can take 90-150 minutes, it's not the best option for those with limited time. Some find the multiple steps and the need for heat application a bit tedious, especially if they're seeking a quick fix.
Time-Consuming Application
65%
35%
For those willing to commit the time, users appreciate the thorough and detailed process that results in smooth, shiny hair. The steps ensure a deeper, more lasting treatment, and some feel that the time invested is worth it for the long-term effects.
The lengthy application time is a significant downside for many, especially those with busy schedules. Some users have expressed frustration with the 90-150 minute window needed for optimal results, leading them to opt for quicker treatments or salon visits instead.
Shine Improvement
90%
A common positive highlight in user reviews is the dramatic improvement in hair shine. After using this product, many customers report that their hair looks healthy, glossy, and vibrant. The natural oils and amino acids appear to nourish the hair, giving it a smooth, lustrous finish.
A few users felt that while their hair was shinier, it also looked slightly greasy or weighed down, especially on finer hair types. For those with thinner hair, the shine may not feel as light and bouncy as expected, leading to mixed results.
Hair Texture Restoration
87%
Many customers mention that the treatment effectively restores damaged hair, giving it a healthier feel after just one application. With regular use, hair appears stronger, more nourished, and significantly less brittle. This makes it particularly beneficial for those with chemically-treated or heat-damaged hair.
However, some users with extremely damaged hair felt that the restorative effects weren’t as pronounced, especially on hair that had been overly processed. For them, the product worked well for smoothing but didn't fully repair the deep damage or breakage.
Scent/Fragrance
80%
20%
The product’s scent is generally liked by users, with most finding it pleasant and not overpowering. It leaves a mild, fresh fragrance on the hair that lasts a few days after application, which many users appreciate for daily wear.
However, a small number of users found the fragrance too strong or synthetic. Those sensitive to scents may find it lingering longer than desired, which could be a turnoff for some individuals who prefer more natural or neutral-smelling products.
Value for Money
92%
Buyers consistently highlight the good value for money, given the high-quality ingredients and professional-level results. The 240mL set lasts for several treatments, which makes it a cost-effective option compared to salon keratin treatments. Many feel they get their money’s worth with long-lasting, impressive results.
Despite the value, some users feel that the initial investment may be high compared to other at-home hair treatments. Those on a tight budget may consider it a bit expensive, especially if they only need occasional touch-ups rather than a full treatment.
Formulation (Chemical Safety)
88%
The formaldehyde-free formula is a big selling point for users concerned about harmful chemicals. Many appreciate that the product offers a safer alternative to other keratin treatments, especially those with sensitive skin or a history of allergic reactions to strong chemicals.
Though the formula is free from formaldehyde, some users with sensitive scalps still reported mild irritation during or after application. A few also noted that it doesn't offer the same strength as traditional treatments containing harsher chemicals, leading to less effective results for some.
Packaging & Dispensing
83%
The packaging is generally appreciated for its functionality, with easy-to-use bottles for both the keratin treatment and clarifying shampoo. The clear labeling helps users follow the application steps without confusion, and the secure bottles ensure the product doesn’t spill or leak during storage.
On the downside, some users feel the packaging could be a bit more durable, with occasional reports of the cap breaking or the product spilling out if not stored upright. A few also mentioned that the bottles could be more compact for easier handling in smaller spaces like bathrooms or travel bags.
Suitability for Different Hair Types
85%
This product is praised for being suitable for a wide range of hair types, from thick and curly to fine and straight. Many users find it effective for improving the texture and shine of their hair, regardless of their hair’s natural state.
However, a few users with fine hair felt that the product made their hair look weighed down or greasy. Those with delicate or very fine hair types may not experience the same volume and lightness as individuals with thicker, coarser hair.
