With consistent use, this treatment helps restore hair's natural shine and suppleness, making it an ideal option for anyone seeking to repair damaged strands and achieve smoother, healthier hair.

Best For

It's a perfect fit for people looking to restore hair’s strength, shine, and overall health. If you're dealing with dry, over-processed hair and want to improve elasticity and manageability, this deep-conditioning mask is an effective and nourishing solution. It also works well for those needing an intensive repair regimen for frequent styling damage.

User Feedback

Effectiveness in Repairing Damaged Hair

89%

Many users rave about how effectively this treatment works to restore hair that has been severely damaged. It strengthens hair fibers, significantly improving texture and reducing brittleness. Users report visible changes after just a few applications, with healthier, shinier hair becoming the norm.

A few users mentioned that the product’s effects were less noticeable on extremely damaged hair after just one use. Some also felt that it took multiple treatments to achieve a more significant transformation, which could be frustrating for those looking for immediate results.

Moisture Retention and Hydration

This treatment is widely appreciated for its ability to hydrate hair deeply, especially for those with dry, brittle strands. The combination of Keratin and Arginine helps lock in moisture, leaving hair soft and nourished. Users enjoy how hydrated their hair feels long after use, even in dry environments.

While most users find it hydrating, a few felt that the moisture effect didn’t last as long as expected, particularly in extremely dry conditions. There were mentions of hair feeling dry again after a couple of days, especially for those with very coarse or porous hair.

Fragrance and Scent Experience

85%

The citrus fragrance is a favorite for many, offering a refreshing and invigorating experience during use. Users enjoy the light, fresh scent, noting that it’s not overpowering but still leaves hair smelling clean and pleasant. It adds a small touch of luxury to the haircare routine.

Not all users are fond of the citrus scent, with some finding it too strong or artificial. A few reviews noted that the fragrance fades quickly, leaving behind no lingering scent, which might be disappointing for those who prefer a lasting fragrance after washing their hair.

Ease of Use and Application

87%

This deep-conditioning mask is praised for its smooth texture, making it easy to apply and distribute through hair. The application process is quick and straightforward, with many users appreciating how easily it rinses out, leaving no greasy residue behind.

While application is generally easy, some users noted that it could be difficult to fully distribute the treatment evenly in thicker hair. A few found themselves using more product than expected to cover their hair, which could be a downside for those with longer or denser hair.

Consistency of Results with Regular Use

88%

For many users, the benefits of this treatment become more evident with consistent use. Hair becomes noticeably healthier and stronger after a few weeks of regular application. Users highlight how it improves hair manageability and reduces breakage over time, making it a reliable long-term solution.

Some users felt that the product didn’t deliver significant long-term improvements unless used regularly. Those expecting fast results after one or two uses may be disappointed by the need for consistent application to see full effects.

Improvement in Hair Strength and Elasticity

90%

One of the strongest points for this treatment is its ability to enhance hair strength and elasticity. Users report a noticeable reduction in hair breakage and improved flexibility after use. This product strengthens the hair shaft, which is especially beneficial for those with damaged or brittle hair.

Although it improves hair strength for many, a few users with extremely fragile hair types found the results to be more subtle than expected. Some felt that while the product helped reduce breakage, it didn’t fully restore their hair’s elasticity to the level they desired.

Value for Money

92%

Users generally agree that this deep-conditioning mask offers great value for money. Given the high-quality ingredients like Keratin and Arginine, many feel that it works well for the price, especially considering the results it delivers in restoring damaged hair. The 150mL size is also seen as a reasonable amount for the cost.

A small number of users noted that while the product works well, it may be considered a bit on the pricey side for some budgets. A few felt that similar results could be achieved with more affordable alternatives, though this is a less common opinion.

Packaging and Dispensing

80%

20%

The packaging is functional and keeps the product sealed, preventing leakage during travel. The cap is easy to open and close, making it convenient to use without wasting product. The design is simple but effective, which many users appreciate.

Several users pointed out that the packaging could be more user-friendly, especially for those with thicker hair. The narrow opening can make it hard to get the product out in one squeeze, leading some to waste product or struggle with dispensing the right amount.

Suitability for Different Hair Types

84%

This treatment is versatile, working well for a wide range of hair types, from curly to straight and fine to thick. Many users with different textures note that it provides nourishing moisture without weighing hair down, leaving it soft and more manageable.

Fragrance Longevity

82%

18%

For those who enjoy fragrance, the citrus scent is refreshing during the application process, and it lingers subtly through the day. Users who appreciate a mild, fresh fragrance are likely to be happy with its scent longevity.

However, some users were disappointed that the fragrance fades too quickly after the wash. For those who prefer their haircare products to leave a lasting scent, this treatment might not meet expectations, as the fragrance dissipates almost immediately.

Impact on Hair Breakage

90%

A standout benefit mentioned by many users is the noticeable reduction in hair breakage. With regular use, this product strengthens the hair shaft and reduces split ends, making hair more resilient to damage. This improvement is particularly beneficial for users with fragile or over-processed hair.

While the reduction in breakage is evident for most, a few users with very fine or highly damaged hair didn’t experience as dramatic results. Some also reported that it helped prevent future breakage but didn’t fully reverse existing damage in a single treatment.

Hypoallergenic and Skin Sensitivity

86%

The formula is gentle, and many users with sensitive skin reported no irritation or adverse reactions. It is free from sulfates and parabens, which makes it a safer option for those concerned about harsh chemicals in their haircare routine.

A small number of users with extremely sensitive scalps experienced mild irritation or itching after use. Although rare, these reports suggest that individuals with very reactive skin might want to perform a patch test before using it regularly.

Long-Term Repair Results

With continued use, many users saw a steady improvement in their hair's overall health. Hair became stronger, more elastic, and less prone to breakage. For long-term damage, this treatment provides ongoing benefits with regular use.

Some users felt that the long-term results weren’t as pronounced as expected. While the product showed improvement in hair strength, some didn’t see as significant a difference in texture or overall appearance after using it for several weeks.
