Effectiveness in Toning Brassiness
88%
Many users are impressed by how effectively this shampoo tones brassiness in blonde hair, especially for those with lighter shades. It neutralizes yellow or orange tones, leaving hair with a cooler, more natural blonde hue. Regular use results in noticeable improvements, with some users commenting that it works better than other toning shampoos they’ve tried.
However, some users report that the toning effect is not as strong on more stubborn brassiness, particularly for darker blonde or heavily processed hair. A few mentioned needing to leave the product on for longer to see desired results, while others felt the results faded quicker than expected.
Fragrance Quality
84%
The amber vanilla scent is a big hit with many users, who find it subtle yet pleasing. It’s described as warm and not overpowering, making it enjoyable for those who appreciate a sweet, cozy fragrance. The scent lingers on hair for a while after use, providing a fresh feeling that users love.
On the downside, some buyers feel that the fragrance is too faint or doesn’t last long enough. A few also mentioned that they prefer a more floral or fresh scent, rather than the warm amber vanilla, which might not appeal to everyone’s preferences.
Hair Softness & Repair
90%
Users consistently praise this shampoo for its ability to repair and strengthen damaged hair. After regular use, many noticed that their hair felt softer, more manageable, and healthier. The combination of amino acids and plant-based proteins seems to be particularly effective for users with dry or damaged strands.
However, a few users with very dry or brittle hair mentioned that they didn’t see dramatic improvement in softness or texture. For those with severely damaged hair, the product alone may not be enough, and they feel they need to supplement it with additional conditioning treatments.
Sulfate-Free & Vegan Properties
92%
The sulfate-free and vegan nature of this shampoo is a significant draw for many customers, particularly those with color-treated or sensitive scalps. Buyers appreciate that it doesn’t strip hair of moisture and is free from harsh chemicals. It's a great option for people looking for a gentle yet effective blonde hair care product that aligns with their ethical preferences.
A small group of users noted that sulfate-free formulas sometimes don’t lather as well as regular shampoos, which they found a bit disappointing. Some also mentioned that the shampoo’s gentle nature means it may not deep clean as thoroughly, especially for users with very oily scalps.
Ease of Use
85%
The 11.2oz bottle is the perfect size for everyday use, and many find it easy to dispense and apply without wasting product. The consistency of the shampoo makes it easy to spread through hair, and it rinses out cleanly without leaving any residue behind. Users also report it’s easy to incorporate into their routine.
However, a few users found the bottle’s design to be a bit awkward for handling, especially when it gets low. Some also mentioned that it’s hard to measure how much product to use, and they occasionally found themselves using more than needed, which can lead to faster consumption.
Long-Term Results
87%
Many users feel that consistent use of this shampoo leads to gradual but noticeable improvements in hair health. Over time, users report their hair feels more nourished, stronger, and less prone to breakage. It’s a solid option for those looking to maintain vibrant, healthy blonde hair without causing further damage.
However, some buyers were disappointed with the long-term effects. They expected more visible results after extended use, with a few users mentioning that the product’s benefits plateaued after a while. A few also noted that they didn’t see enough of an improvement in the overall condition of their hair to justify ongoing use.
Packaging & Dispensing
82%
18%
Users appreciate the simple and sleek design of the bottle, which fits well in most shower caddies. The flip-top cap ensures ease of dispensing, minimizing spills and messes. Many also find the packaging practical for travel, with a size that’s easy to pack without taking up too much space.
On the downside, a few users have noted that the cap sometimes doesn’t seal tightly, which can lead to leaks, especially when traveling. Some also mentioned that the bottle could benefit from a pump for more controlled dispensing, as it can be tricky to squeeze out the last bits of product when nearing the end.
Overall Value for Money
89%
Many users consider this shampoo a great value, especially given its high-quality formulation. The fact that it’s sulfate-free, vegan, and works well for toning blonde hair makes it a solid investment for those with color-treated hair. With regular use, users find that the 11.2oz bottle lasts for several weeks, providing good cost efficiency.
However, some buyers feel that the price is slightly higher than other toning shampoos on the market. A few noted that while it performs well, they can find cheaper alternatives that also work to reduce brassiness, making the product feel less like a standout value.
User Skin Compatibility
78%
22%
For the most part, users with sensitive skin or scalps find this shampoo gentle and non-irritating. Several customers with sensitive skin report no itching or discomfort after use, which is a big plus. It’s also well-suited for those with color-treated hair who are looking for a shampoo that won’t aggravate scalp sensitivities.
That said, some users did experience irritation or dryness after using this product, particularly those with very sensitive or dry scalps. A few customers mentioned that it left their scalp feeling tight, and they had to switch to a more hydrating shampoo to balance it out.
Depth of Toning (Leave-on Time)
80%
20%
Many buyers find that leaving the shampoo on for a few minutes helps achieve a deeper, more vibrant toning effect. They recommend this extra step to get the best results, particularly for hair with stronger brassiness. Some users say this makes a noticeable difference in the final outcome, especially with consistent use.
However, others feel that leaving it on for a longer time doesn’t significantly enhance the results and is a bit too much hassle. A few customers noted that the added time doesn’t necessarily deliver better toning, which can be inconvenient for those looking for a quick, effective solution.
Product Longevity (Bottle Size vs Usage)
83%
The 11.2oz size seems to be the right balance for most users, providing a sufficient amount of product without needing to repurchase too quickly. Many buyers mention that it lasts for a decent amount of time with regular use, and the shampoo’s consistency ensures that it’s economical in the long run.
On the other hand, some users with thicker hair or those using it every day reported using up the bottle faster than expected. This led some to feel that the bottle size was a bit too small for long-term use, especially considering the price point.
Results for Damaged Hair

For those with damaged or over-processed blonde hair, many users found that this shampoo helped restore some strength and softness. It worked well at helping hair look less brittle, with a smoother texture. Several reviews mention it as a part of a good repair routine alongside other restorative products.
