Description
Description
A leave-in that behaves like water rather than cream. Seventeen ingredients, none of them an oil or a silicone, so it can go through fine hair without the flatness that usually follows a leave-in treatment.
Hydrolysed keratin sits fifth — a protein for hair that's been bleached, heated or simply worn long enough to fray at the ends. Furcellaria lumbricalis, a red algae from the Baltic, works alongside it, and the whole thing is preserved with radish root ferment. 99% natural origin, certified COSMOS Natural by Ecocert.
How to use
How to use
Spray through clean, damp hair — mid-lengths and ends, not the roots — then comb it through and carry on as normal. Nothing to rinse and nothing to wait for.
It goes on before anything else you're using, so heat protectant, cream or oil all layer over the top. Daily is fine. Avoid direct contact with the eyes.
Who is it for?
Who is it for?
Damaged, frizzy or fragile hair, and especially fine hair that needs help but can't carry a cream. If leave-in treatments have always left your hair looking greasy at the roots by lunchtime, the absence of oil and silicone here is the reason to try this one.
This is the one product in our range that isn't vegan. The keratin is derived from sheep wool — ethically sourced and cruelty free, but animal-derived all the same. It's also noticeably fragranced, with fragrance third on the ingredient list and four allergens declared, which matters more than usual in something that stays in your hair all day.

Ingredients / INCI
How to use it
Every wash, or every day if you want. There's nothing in it to overdo.
Clean, damp hair
Towel-dried rather than dripping. A mist on soaking hair mostly runs straight back out of it.
Spray the mid-lengths and ends
Where the damage actually is. The roots are new hair and don't need any of this.
Comb through, then style
Nothing to rinse out. Whatever else you use goes on after this, not before it.
Mist, cream or oil
Three ways to treat hair after washing. The differences matter most if your hair is fine.

What's inside and why it's there
Seventeen ingredients, 99% of natural origin, certified COSMOS Natural by Ecocert. Preserved with radish root ferment, no GMO ingredients, recyclable packaging. Contains keratin derived from sheep wool, so this product is not vegan.
Hydrolysed Keratin
Broken into fragments small enough to get into damaged hair rather than sit on the outside of it. Hair is mostly keratin already, which is why this is the protein that gets used when hair has been bleached or heat-styled into fragility.
Furcellaria Lumbricalis
A red algae harvested from the Baltic, and not something you'll see on many labels. It works with the keratin on the smoothing and detangling side of the formula.
No Oils, No Silicone
Read all seventeen ingredients and you won't find either. That's the reason a leave-in treatment can go through fine hair here without the roots looking greasy by mid-afternoon.
Questions people ask before buying
No, and it's the only thing we make that isn't. The keratin is derived from sheep wool — ethically sourced and cruelty free, but animal-derived, which puts it outside the definition of vegan. If that's a line you hold, this is the product in our range to skip.
Mid-lengths and ends, on clean damp hair. Your roots are the newest hair on your head and haven't been damaged yet — anything you put there is the reason hair goes flat.
No, it stays in. Spray, comb through, then style as usual. There's no waiting time and nothing to wash away afterwards.
Yes. It's light enough that daily use won't build up on the hair, and there's nothing in it to overdo in the way you might with a heavy treatment.
There's very little in it that could. No oils, no silicones, no butters — the seventeen ingredients are mostly water, the keratin, the algae and what preserves them. It's the lightest thing you can put on hair and still call it a treatment.
Some hair can, yes. If yours starts feeling stiff or straw-like after a couple of weeks of daily use, that's the sign — cut back to two or three times a week and use a moisturising conditioner alongside. Most people never run into it, but it's worth knowing before you start.
Hair is largely keratin to begin with, so a hydrolysed version — chopped into small enough fragments to get inside — can fill in where bleach, heat or time have worn the strand thin. It's a temporary patch rather than a cure, which is why you reapply it after each wash.
Yes, and it goes on first. Spray this through damp hair, then your heat protectant, cream or oil over the top. Applying it after an oil means it never reaches the hair.
Noticeable, and it lingers — fragrance is third on the ingredient list, which is high for something that stays in your hair all day. It's fresh and aquatic with floral and vanilla behind it, built from bitter orange, lemon peel and geranium oils, with linalool, limonene, citronellol and pinene declared.
Goes on before
This is the first thing on damp hair. Everything else layers over it.
