Most conditioners are made for thick hair. On fine hair, they leave waxy layers that crush volume instead of protecting it.
Thick, waxy formulas
They coat each strand in a heavy film. Flat hair as soon as it dries.
Creams that leave residue
Build-up dulls your hair wash after wash. Shine gone.
Detangling with no protection
The brush pulls, fine hair snaps. Your brush fills up a little more every morning.
That's why our formula works on the fibre first, where fine hair breaks. The detangling agents let the comb glide, and hydrolyzed keratin fills in the fragile spots. Hair bends instead of breaking, without ever being weighed down.
Freshly washed. Already flat.
Dual-Action Detangle & Nourish Technology, without the weight
Unlike regular conditioners that only coat the hair, our system does both:
Step 1 — DETANGLE
Light detangling agents coat each strand while you rinse: the comb glides, nothing pulls, and breakage from brushing goes down.
Step 2 — NOURISH
Hydrolyzed keratin, the same as in our shampoo, goes where fine hair needs it most: mid-lengths and ends. Softness and shine, zero residue.
The result: the comb glides, less hair in your brush, and hair that's visibly softer and easier to style, with no flat look.
Results
What you'll notice first
Most of our customers notice a difference within the first few uses.
From the very first rinse
The comb slides through without pulling. Detangling stops being a fight.
The first time you dry it
No flat look. The volume stays, the texture feels light and clean.
Within the first week
Less hair in your brush in the morning. Less breakage when you detangle.
Softness you can feel
Silky lengths to the touch, with no residue and no greasy film.
After 2 to 4 weeks
Hair that's visibly smoother and easier to style, day after day.
One minute in the shower
After shampooing, apply to the lengths and rinse. That's it.
Comparison
Why other options leave fine hair flat
Thick formulas, endless waiting times and greasy oils don't suit fine hair that needs a light touch.
Drugstore conditioners
Thick formulas made for normal to thick hair. A guaranteed flat look on fine hair.
Hair masks
15 minutes of waiting, heavy residue, too rich for everyday use.
Styling oils
They grease the roots, darken light hair and are impossible to dose on fine hair.
The Nourishing Rosemary & Keratin Conditioner gives you easy detangling and softness, without the flat look or the residue.
Ingredients
Three actives, one goal
A short formula, designed for fine hair.
Hydrolyzed keratin
Hair is made of keratin. In fragments fine enough to bind to the fibre, it smooths and strengthens from mid-lengths to ends.
Rosemary extract
The Celestine signature, the same extract as in our shampoo. Your routine speaks the same language from step 1 to step 2.
Olive oil
The emollient that softens the fibre for a silky feel, in an amount designed never to weigh hair down.
Also in the formula: vitamin E (tocopherol) and vitamin C, antioxidants that help protect the fibre.
Honestly
Why most women with fine hair gave up on conditioner
If you stopped using conditioner because it left your hair flat, you're not alone. It's the number one reason we hear.
The problem was never conditioner itself: it's that no formula was made for fine hair. So we developed one in Québec. Light enough not to weigh anything down, nourishing enough that detangling stops costing you hair.
And if it doesn't win you over, our 60-day guarantee takes care of the rest.
60-Day Money-Back Guarantee
We believe in our conditioner. Make it part of your routine, and if it's not right for you, you can ask for a refund within 60 days of delivery.
Results may vary. The guarantee covers your satisfaction with the product, not specific cosmetic results.
Frequently asked questions
No, and that's the whole point of this formula. It's light enough to rinse out completely, with no waxy film or residue. Your hair stays soft and keeps its volume when it dries.
Yes, that's exactly what it's for. The detangling agents let the comb glide instead of pulling, and hydrolyzed keratin strengthens the fibre where it's fragile. Less pulling, less breakage, less hair in your brush.
On the mid-lengths and ends, never at the roots. Apply after shampooing, leave it on for one minute, rinse. That's it.
No. Salon treatments leave a coating on the hair to smooth it. Hydrolyzed keratin is broken down finely enough to penetrate the fibre and strengthen it from within. It won't straighten your hair or change its texture, it gives it more body.
Yes, they're designed to work together. The shampoo cleanses in step 1, the conditioner detangles and nourishes in step 2. Same rosemary extract, same hydrolyzed keratin, the same signature from start to finish.
Every time you wash, after your shampoo. It's light enough to use as often as you need, with no build-up.
Yes, it won't affect your colour. It's formulated to be gentle on colour-treated hair.
Yes, it won't turn white hair yellow. It's formulated to be gentle on white and grey hair.
Yes. It has no added fragrance and no parabens, and it's applied to the lengths, not the scalp.

Très facile à utiliser très doux et efficace ce fut un très bon achat!
J'aime bien le revitalisant, mes cheveux sont plus doux depuis que j'utilise le shampooing et le revitalisant Célestine, je perds moins mes cheveux mais je ne les trouve pas vraiment plus épais, ce qui me déçois beaucoup... dans vos pubs on nous dit que nous verrons des bons résultats d'ici 3 semaines, cela fait plus de 3 mois que j'utilise votre produit et je ne trouve pas mes cheveux plus épais, cela dit je veux continuer d'utiliser vos produits car mes cheveux n'ont jamais été aussi doux même après avoir utilisé différents shampooings et produits pour la repousse de cheveux... j'espère que je vais voir de la repousse bientôt...
Bonjour j’adore le revitalisant Célestine ,il complète bien le shampoing Célestine ,il laisse les cheveux doux lustres et facile à coiffer merci de nous offrir d’aussi bons produits qui nous permettent d’être plus heureux 😀
I do not recommend !!! They make the publicity so you buy the conditioner that comes to almost 50$ with the shipping and its not even the conditionner that is good for your hair, its the shampoo... anw not impress.
Mes cheveux étaient devenus ternes et cassants avec les années. Ce revitalisant leur redonne de la douceur sans rien alourdir. Une belle trouvaille québécoise.
Je vis en France et ma cousine me l'a rapporté du Québec. Texture légère, cheveux souples, rinçage impeccable. J'espère une livraison en France bientôt.
Mes cheveux clairsemés paraissent plus fournis juste parce qu'ils cassent moins et gardent leur corps. Aucun film, aucune lourdeur. Chapeau pour ce produit d'ici.
Bonne découverte grâce à une publicité Facebook. Le démêlage est vraiment plus facile. Le prix en solo est un peu haut, prenez le duo avec le shampoing.
Aucune irritation malgré ma peau réactive. Je l'applique sur les longueurs et mes cheveux colorés gardent leur éclat. Je recommande à toutes mes amies.
Le premier revitalisant qui respecte mon cuir chevelu sensible. Je l'applique sur les longueurs comme indiqué et aucune réaction. Le résultat est superbe.
