The serum offers a delicate floral fragrance that many find subtle and pleasing, contributing to a calming pre-sleep routine. Users appreciate that the scent isn't overpowering and doesn't linger too strongly in the hair, making it a good option for people sensitive to strong fragrances.
Not everyone is a fan of the fragrance; some users found it too floral or artificial for their preferences. Additionally, those sensitive to scents reported irritation or discomfort, especially if applied heavily. A few mentioned it didn’t fade quickly enough, causing issues with scent sensitivity.
Softness and Shine Improvement
92%
After using this serum overnight, most users notice a dramatic improvement in hair softness and shine. It makes hair feel silky to the touch and helps restore natural luster without weighing it down. For those with coarse or dry hair, the effect is especially noticeable, as it brings back a healthy, radiant glow.
Despite its effectiveness for many, some users felt the shine didn’t last as long as expected and faded by midday. A few reviewers noted that while it added softness, it did not provide the level of shine they had hoped for, especially for those with thicker or more porous hair.
Ease of Use/Application
86%
Most users find it easy to apply the serum before sleep, thanks to its smooth, non-greasy texture. The serum absorbs fairly well and doesn’t leave a sticky residue, allowing users to rest comfortably without worrying about transfer onto pillowcases. The 90mL bottle lasts a decent amount of time, too.
A few users mentioned that the application can be tricky if you have long or thick hair, as it requires careful distribution to avoid clumping. Some felt the serum’s texture was too thick, especially for finer hair types, leading to uneven application.
Protection Against Heat Styling
88%
Users appreciate the added heat protection, particularly for those who blow-dry or frequently use styling tools. The serum acts as a barrier, helping prevent heat damage while promoting smoother, healthier-looking hair post-styling. This makes it a useful addition to daily haircare routines for anyone using high-heat tools.
While it provides some protection, a few users felt that it wasn’t enough to completely prevent heat damage for those who style their hair frequently or at higher temperatures. Some still experienced breakage or frizz after heat styling despite using the serum.

For most users, the serum absorbs quickly into hair, especially when applied to damp or dry hair. It doesn’t leave a greasy residue, allowing users to go to bed without the worry of product buildup. Those with normal to slightly dry hair types appreciate the lightness of the serum.
For thicker or very dry hair, absorption can be slower, requiring a bit more time for the product to fully sink in. Some users also mentioned needing to apply extra product for even distribution, which can impact the speed of absorption, especially for long or dense hair.
