Our analysis includes authentic, high-quality feedback, ensuring that only the most reliable reviews, free from spam or exaggeration, were considered in this comprehensive evaluation.

Effectiveness for Hair Smoothing
88%
Many users mention that this shampoo delivers smooth, sleek hair without weighing it down. It works particularly well for frizz-prone hair, leaving a noticeable shine and softness after use. The keratin and argan oil blend helps to provide a polished, salon-like finish with each wash.
Some users noted that while it smooths hair, the results aren't long-lasting for very frizzy or coarse textures. A few felt that their hair reverted back to its natural state after a few hours, especially in humid conditions, meaning the smoothing effect doesn't always hold throughout the day.
Frizz Control
85%
This shampoo is praised for its ability to tame frizz, even in humid weather. Reviewers with naturally wavy or curly hair report that their hair feels more controlled and less frizzy after consistent use. Many also appreciate that it doesn't leave hair feeling sticky or greasy.
Not everyone felt the frizz control was strong enough for their hair type. Some users with extremely thick or unruly hair found that while it helped a little, it didn't fully eliminate flyaways or frizz. Others mentioned needing to pair it with other styling products for optimal results.
Shine and Glossiness
90%
Numerous reviews highlight that this shampoo adds significant shine and gloss, especially for dull or damaged hair. Argan oil's moisturizing properties seem to work effectively, leaving hair with a natural-looking radiance. The glossy finish is often noted as one of its most noticeable results.
Some users feel that the shine is subtle or short-lived, especially for those with very dry hair. While it gives a healthy sheen, a few mentioned that it doesn't quite match the glossiness of more expensive salon products, especially after a few washes.
Hydration and Moisture
84%
Reviewers with dry or brittle hair reported feeling the moisturizing effects of this shampoo almost immediately. The hydration provided by the argan oil and amino acids is often mentioned as one of the product's strong suits, leaving hair softer and less prone to breakage.
A handful of users with very dry or coarse hair found that the moisture level wasn't enough to fully combat dryness. Some stated that while their hair felt hydrated right after washing, it became dry again by the next day, especially in winter months.
Suitability for Color-Treated Hair
89%
This shampoo is highly praised by users with color-treated hair for being gentle and sulfate-free. Many reviewers found that it did not strip away color or cause fading, and it even seemed to help maintain their hair’s vibrancy over time. The gentle formula helps preserve salon treatments.
A few users with color-treated hair mentioned that they experienced some fading with regular use, especially with frequent washes. They suggested that this shampoo might not be as effective at preserving color for certain hair dyes, particularly those with more delicate pigments.
Restorative Benefits for Damaged Hair
87%
This shampoo is well-regarded for its restorative properties. Many customers report seeing improvements in hair texture and overall health after several weeks of use. The keratin and amino acids seem to repair damaged strands, leaving them stronger and more resilient.
However, some users didn't notice dramatic restoration of severe damage. Those with extremely damaged or thinning hair felt the shampoo provided only mild improvements. They suggested that the product works better for maintenance rather than as a complete repair solution.
Gentleness on Scalp
92%
Reviewers with sensitive scalps appreciated the gentle formula, with many noting that the shampoo didn't cause irritation or dryness. The sulfate-free ingredients seem to provide a soothing effect, which is especially beneficial for those prone to scalp issues like itchiness or flakiness.
A small portion of users with very sensitive scalps mentioned that the product didn't alleviate all of their scalp issues, such as dandruff or dryness. Some still found it left their scalps feeling slightly tight after use, despite being sulfate-free.
Fragrance
70%
30%
Many users found the fragrance to be pleasant, fresh, and not overpowering. The light scent lingers for a short time, which some reviewers enjoyed as it wasn't too strong or artificial. The fragrance adds to the overall sensory experience without being overwhelming.
The fragrance wasn't universally liked, with some customers finding it too subtle or even somewhat unpleasant. A few described it as too floral or artificial, which clashed with their personal preferences. The scent also tends to fade quickly after washing, leaving no lasting impression.
Ease of Use and Application
91%
Users appreciate the creamy texture of the shampoo, which makes it easy to apply and distribute evenly through hair. The product lathers well and requires only a small amount to cover the entire scalp, making it an efficient option for daily use.
Some users found that it didn't lather as much as they expected, requiring them to use a larger amount. Others mentioned that the product can be a little slippery, making it harder to keep a good grip while washing in the shower.
Volume Boosting Claims
75%
25%
A few users with fine hair reported slight improvements in volume and fullness after using this shampoo. It seems to provide some light volume, especially when paired with other styling products, which is a plus for those with thinner hair types.
However, the volume-boosting effect was not as strong as expected for many users. People with flat or very fine hair often felt that it didn’t provide enough lift, leaving their hair looking flat after use. Some suggested that this shampoo might be better suited to those with thicker, denser hair.
Packaging and Dispensing
93%
The packaging of this shampoo is highly praised for being user-friendly and efficient. The bottle is sturdy, and the pump dispenser allows for controlled and mess-free application. Many reviewers appreciate the size and design, making it easy to use in the shower.
A few users mentioned that the pump dispenser can be tricky to use as the bottle gets emptier, especially with thicker formulations. Some found that the last bit of product was hard to dispense without shaking or tilting the bottle.
Overall Value for Money
88%
Most users consider this shampoo to be a good value for the price, given its quality ingredients and results. It is seen as an affordable option compared to other salon-quality shampoos. Many buyers feel they are getting a high-performing product without breaking the bank.
Some buyers feel that while it works well, it is still priced higher than other drugstore options. A few users expressed that they might opt for more budget-friendly products for similar results, especially since the volume-boosting effects weren't as pronounced as anticipated.
