Spam, bot, and incentivized reviews were carefully filtered out to ensure that only authentic, high-quality user experiences contributed to the scores.

Hydration & Moisture

91%

Many users praise this shampoo for its ability to deeply hydrate without leaving hair greasy. It offers lasting moisture, even for those with dry or brittle hair, and provides a smooth, healthy shine that enhances hair texture. This is particularly appreciated by people with frizzy or damaged locks, as it softens and nourishes the strands effectively.

Some users mention that while it hydrates, it doesn’t provide enough moisture for extremely dry hair. Others note that they had to use a conditioner alongside the shampoo for the best results, which can be an inconvenience for those looking for a more streamlined routine.

Gentleness & Skin Compatibility

The sulfate-free formula makes this shampoo suitable for sensitive scalps and skin, with many buyers noting it causes no irritation. People with delicate or allergy-prone skin appreciate how gentle it is while still effectively cleaning the hair. It’s ideal for anyone looking for a mild product that doesn’t strip natural oils.

However, a few users with sensitive scalps report that the shampoo, while gentle, still causes some irritation after frequent use. These complaints typically come from individuals with very reactive skin, so this might not be the best choice for them.

Fragrance Quality

83%

The coconut scent of this shampoo is subtle yet pleasant, making it a nice option for users who prefer more understated fragrances. Many find it refreshing but not overpowering, which makes it perfect for daily use without overwhelming the senses.

Some users expected a more pronounced coconut scent, and a few were disappointed by how quickly it faded after washing. Those who love strong, lingering fragrances may find the mildness a downside.

Effectiveness for Damaged Hair

87%

This shampoo excels at improving the overall health of damaged hair. Many users report noticeable improvements in hair texture, reduced breakage, and stronger strands over time. It’s especially effective for people with color-treated or heat-damaged hair, providing a refreshing boost of strength and hydration.

However, some users with severely damaged hair found that it didn’t fully repair their hair on its own. They recommended pairing it with other treatments for optimal results, as it might not restore very weak or chemically processed hair completely.

Sulfate-Free Formula Performance

As a sulfate-free shampoo, this product is gentle and helps retain the natural oils in hair. Users with dry or curly hair especially appreciate this aspect, as it prevents further stripping of moisture. It cleanses effectively without harsh chemicals, leaving hair feeling clean but not dry.

While it works well for most, a few reviewers mentioned that the lack of sulfates leads to less lather than they’re used to. This can be a bit off-putting for people who prefer rich, bubbly lather when shampooing.

Ease of Use & Application

The 8.5oz bottle is compact and easy to handle, making it convenient for both at-home and travel use. Its straightforward design makes it easy to dispense the right amount of product, and the packaging feels sturdy.

Lather Quality

28%

Some users appreciate that the shampoo still cleanses well despite not producing as much lather as other products. For those who don’t mind less foam, it delivers a refreshing clean without drying out the scalp.

Shine & Glossiness Post-Use

85%

The shampoo leaves hair with a noticeable shine, which many users love. It enhances the natural luster of hair without weighing it down, making hair look healthy and well-cared-for even on busy mornings.
