Helps hair feel smoother, stronger, easier
Why this exists
Leave-in hair products often earn their immediate smoothness by leaning on silicones, which can give an elegant finish but do little beyond surface slip. This spray is built differently : hydrolysed keratin is used as the primary active so the formula can deposit a low-molecular-weight protein fragment onto the hair shaft, where it helps reinforce areas of cuticle wear as the hair dries. Lactic acid supports the pH conditions that favour cuticle closure, helping the shine look more structural than cosmetic. Furcellaria Lumbricalis extract adds lightweight film-forming support, while the almost entirely aqueous base keeps the mist feather-light so it does not weigh hair down. The result is a no-rinse treatment that aims to improve manageability, reflection, and the feel of the hair surface without adding heaviness.
Inside the formula
The key actives
02
Furcellaria Lumbricalis Extract
Furcellaria Lumbricalis Extract
Provides lightweight polysaccharide film-forming support that helps hold moisture at the hair surface between washes.
03
Lactic Acid
Lactic Acid
Helps maintain the pH that supports cuticle closure, so the finish looks smoother and more reflective.
On the hair and scalp
Water-light and almost weightless on contact. It mistes easily through damp hair and absorbs without a greasy feel. Once dry, the finish is smooth, soft at the surface, and visibly shinier rather than coated.
The application
How to use this
-
1
Spray onto damp hair
Use two to four sprays on clean, towel-dried hair immediately after washing. Focus on mid-lengths and ends, or where the hair feels most in need of smoothing.
-
2
Comb through evenly
Run a comb through from root to tip to distribute the mist from side to side. This helps the keratin and conditioning film settle evenly across the hair shaft.
-
3
Style without rinsing
Leave the mist in place and style as usual. It is designed to be a no-rinse step, so the finish develops as the hair dries.
What to expect
On the hair, over time
Day 1
Hair combs through more easily after washing, with less pulling as you distribute the mist. As it dries, the surface looks smoother and catches the light more evenly.
Week 1
Frizz and flyaways appear more controlled through the day, with a cleaner finish between washes. The hair feels easier to manage without needing extra product.
Week 4
Hair may feel progressively more settled and consistent in texture, especially through the lengths. Regular use can build a better baseline for shine and manageability between wash days.
The deeper detail
The formulation, the provenance, the standard
Formulation
The base is almost entirely aqueous, with Butylene Glycol providing the only significant humectant alongside water. This lightness is deliberate: a leave-in product that sits heavily on the hair defeats its own purpose, adding weight rather than care. Sodium Levulinate and Sodium Benzoate serve as the preservation system, chosen for their compatibility with natural formulation profiles. Phenethyl Alcohol contributes both preservation and a subtle floral aromatic note that integrates naturally into the fragrance composition.
Hydrolyzed Keratin is the primary active, present at a concentration that allows meaningful surface deposition on the hair shaft. Its molecular weight is calibrated for cuticle-level binding rather than cortical penetration : this is a surface treatment that improves what you can see and feel rather than a reconstructive mask. Furcellaria Lumbricalis Extract, derived from fermented algae, contributes a lightweight conditioning film. Lactic Acid closes and smooths the cuticle at a functional pH level. The fragrance is composed from certified natural essential oils : bitter orange peel, lemon peel, geranium flower, and their aromatic components, including naturally occurring linalool, limonene, and citronellol.

Reviews and reflections
-
easier to work with
After about a week on damp hair, my curls separate easier and look smoother without going flat. The spray's so light I go through it quickly, but it does the job. Deffo works better than my old leave-in.

comb glides through
Comb moves through damp hair like butter now. Frizz around my crown is way less obvious once dry.

shiny
Works. Just don't overdo it.

does the job
Lightweight and makes detangling easier after washing my colour-treated hair. I sprayed it through the mid-lengths before blow-drying and it left a nice shine, though the scent is a little strong for me.
-
actually works for fine hair
My very fine hair usually looks dead flat by lunch, but this gives it a cleaner shape and visible shine without any weight. One or two sprays on damp lengths, comb through and the ends behave so much better. Fresh citrus scent that isn't sickly. Only gripe is the 100ml goes fast for the price, but I keep buying it.

good in humidity
Singapore humidity usually makes my hair fuzzy but this keeps it neater for longer. Spray, comb, done. Shine's nice, not greasy.

Can I use it on dry hair?
Yes, it can be used on damp or dry hair for added shine and a smoother surface. For best distribution, comb it through after spraying.
Does it contain silicones?
The formula is positioned as a keratin mist rather than a silicone-heavy smoother, using hydrolysed keratin, algae extract, and lactic acid for the finish.
