Leave-in hair oil

A leave-in hair oil that protects, nourishes, and enhances your hair

A lightweight, non-greasy daily dry hair oil—a natural leave-in treatment designed to nourish the hair shaft, tame frizz, protect against heat, and bring out your hair’s natural shine.

A leave-in dry oil to protect, nourish, and enhance your hair every day. Madame d’Alexis Day Serum combines plant-based ceramides,organic jojoba oil, orange blossom essential wax, natural antioxidants, and heat-protective ingredients in a lightweight dry oil formula.

Unlike a scalp serum, it can be applied to damp or dry hair, focusing only on the mid-lengths and ends, without weighing hair down, leaving a greasy residue, or making it feel stiff. It’s the ideal daily routine to smooth the hair shaft, make styling easier, protect hair before blow-drying, and add shine.

Plant-based ceramides and jojoba oil: a hair oil that nourishes without leaving hair greasy

Plant-derived ceramides help restore the hair fiber’s lipid barrier. When used as a daytime serum, they help protect the cuticle, minimize moisture loss, improve texture, and reduce porosity in damaged hair.

Organic jojoba oil nourishes without leaving a greasy residue, adds suppleness, and helps tame the hair. Its light texture makes it an ideal ingredient in a pre-blow-dry serum, as a finishing touch to your styling routine, or as part of your daily routine for dry ends.

01 Plant ceramides

Strengthen the lipid barrier, protect the hair shaft, reduce moisture loss, and improve manageability.

02 Organic jojoba oil

Deeply nourishes the hair shaft, leaving it soft and shiny, without feeling greasy or weighing it down.

A leave-in dry oil to protect the lengths of your hair

The Day Serum does not require rinsing. It acts as a finishing and protective treatment, to be applied in small amounts to the mid-lengths and ends. Its fluid texture helps smooth the cuticle, control frizz, and make hair more supple, shinier, and easier to style.

01 Orange blossom essential wax

Locks in moisture, leaving the skin supple, radiant, and with a luxurious feel.

02 Thermal-protective ingredients

Help protect hair up to 200°C before using a blow dryer, straightener, or other heated styling tool.

03 Natural antioxidants

Protect the fiber from external damage, pollution, UV rays, and oxidation.

Dry Hair Oil vs. Regular Hair Oil: What's the Difference?

Most hair oils are rich, heavy oils designed for long-term use or for very dry hair. They deeply nourish the hair but often leave an oily residue, weigh down the hair shaft, and require rinsing.

A dry hair oil works differently. Its ultra-light texture absorbs quickly without leaving a greasy film, residue, or a stiff, cardboard-like feel. Apply just a few drops to damp or dry hair, and it works immediately: it smooths the cuticle, tames frizz, and brings out shine.

Madame d’Alexis Day Serum is formulated as a lightweight, precision hair oil —neither too rich for fine hair nor too light for dry hair. The combination of plant-based ceramides, organic jojoba oil, and orange blossom essential wax provides nourishment, protection, and shine without compromising on lightness.

How to Choose the Right Dry Hair Oil?

Not all dry oils are created equal. The best dry hair oil isn't just the one that adds shine—it's the one that protects, nourishes, and tames your hair without causing buildup.

Repairing ingredients: A dry oil without ceramides or protective ingredients only smooths the surface. Plant-based ceramides work on the hair fiber’s structure, not just its appearance.
The origin of the ingredients: Choose a formula based on organic jojoba oil—which is structurally similar to natural sebum—rather than mineral oils or silicones, which create an occlusive film without providing nourishment.
Heat protection: essential if you use a hair dryer, straightener, or curling iron. The Day Serum protects the hair shaft up to 200°C thanks to its heat-protective ingredients.
The silicone-free formula: Silicones provide instant shine but build up on the hair shaft. A silicone-free dry hair oil provides long-lasting nourishment without causing buildup.
The right texture: For fine hair, apply 1 drop to the ends. For thick or curly hair, apply 2 to 3 drops to the mid-lengths and ends. For very dry hair, apply to damp hair to lock in moisture.

What you'll see, week after week

From the very first use: hair is immediately softer, shinier, and easier to style. Frizz is tamed, and the ends are less dry.
After 2 weeks of daily use: the cuticle is visibly smoother. Colored or damaged hair regains its shine. Blow-drying is faster, and styling is more precise.
After 4 weeks: the hair fiber is better protected. The lipid barrier, strengthened by plant-based ceramides, reduces moisture loss between washes. The hair is more resistant to heat and external aggressors.
Daily routine: Use the Day Serum in the morning on damp hair before styling, or in the evening on dry ends as part of your hair care routine. Just 1 to 3 drops are enough.

For which hair type?

Serum for dry or damaged hair: ceramides help restore the lipid barrier, while jojoba nourishes without weighing the hair down.
Serum for curly, wavy, and coily hair: reduces frizz, softens the hair shaft, and brings out natural definition.
For colored or chemically treated hair: It protects damaged strands and helps preserve the color's shine.
For all hair types before blow-drying or straightening: the ideal hair-smoothing serum, with natural heat protection up to 200°C before using heated styling tools.

FREQUENTLY ASKED QUESTIONS

Why has my hair lost its natural shine? Why has it become coarse and lifeless?

▼
Shine: a question of lipids Natural shine comes from the lipids that coat the hair fiber. These lipids create a smooth protective layer that reflects light. When this layer is damaged or absent, light is no longer reflected and your hair appears dull and coarse. Harsh shampoos strip away these protective lipids. Hard water clogs the cuticles and prevents the lipids from spreading evenly. Heat (hair dryers, flat irons, sun) oxidizes the lipids and renders them ineffective. Pollution and styling product residue create an opaque layer that blocks light. Why hair becomes coarse Coarse hair lacks lipids and moisture. Without lipids, the cuticle remains open and rough. Without moisture, the fiber becomes brittle and loses its elasticity. It's a twofold problem: lack of nutrition (lipids) and lack of moisture. Conventional shampoos aggravate the problem by removing natural lipids. You end up in a cycle: less lipids, more roughness, the more you try to repair, the more you damage. How this serum repairs This serum contains plant ceramides that replenish the natural lipid layer. Organic jojoba oil is rich in natural lipids that resemble human sebum. Together, they restore the smooth protective layer. Hyaluronic acid deeply moisturizes. Organic hydrosols provide antioxidants that protect against oxidation. After a few applications, your hair regains its natural shine. After 2 to 3 weeks, it is visibly smoother and shinier. This is the effect of the gradual restoration of the lipid layer.

What do ceramides and jojoba oil really do for hair? How does it work scientifically?

▼
Ceramides: rebuilding the lipid barrier Ceramides are natural lipids that form the protective barrier of the skin and hair. When this barrier is damaged, water escapes and the hair becomes dry. Plant-based ceramides fill the gaps in this barrier and restore it. Once restored, the barrier retains moisture inside the fiber. This is why your hair stays hydrated longer. Ceramides also create a smooth layer that reflects light and creates shine. Jojoba oil: a natural lipid identical to sebum Jojoba oil is unique because its chemical composition is exactly like human sebum. Your scalp recognizes jojoba oil as natural and accepts it easily. Unlike mineral oils, which remain on the surface, jojoba oil penetrates the fiber and nourishes it from within. It provides essential fatty acids that your scalp cannot produce on its own. It also protects against dehydration by creating a barrier against water evaporation. The interaction between ceramides and jojoba oil Ceramides rebuild the barrier (structural action). Jojoba oil nourishes and protects (nutritive action). Together, they create a stronger, more hydrated, and shinier fiber. Hyaluronic acid deeply hydrates. Organic hydrosols provide antioxidants and minerals. It's a comprehensive approach that addresses all aspects of hair health. Your hair is protected (ceramides), nourished (jojoba oil), hydrated (hyaluronic acid), and revitalized (organic hydrosols).

I have fine or oily hair. Won't this serum weigh my hair down or make it look greasy?

▼
For daily use, a daytime hair serum with ceramides and organic jojoba oil should be applied as the final step in your hair care routine after shampooing and, if desired, conditioning. Apply a small amount to towel-dried or dry hair, then smooth it over the lengths and ends without rinsing. The heat-protective active ingredients make it particularly useful before blow-drying or using a straightener, up to 200°C. Antioxidants No, this serum does not weigh down fine hair. This is a legitimate concern. Many people think that serums with oil automatically weigh hair down. This is not true. It all depends on the formula and the amount used. This serum is formulated to nourish without weighing hair down, even fine hair. Jojoba oil is light and penetrating. It does not create a greasy film on the surface. Ceramides strengthen without thickening. Hyaluronic acid moisturizes without adding weight. The result: deep nourishment without feeling heavy. Why this serum does not make oily hair greasy Jojoba oil is similar to human sebum. When you apply it to oily hair, your scalp recognizes this oil as natural and does not produce more sebum to compensate. On the contrary, it gradually regulates itself. The less you aggress your scalp, the less sebum it produces. This serum soothes and regulates without aggression. Ceramides strengthen the barrier, which reduces sebum overproduction. After a few weeks, your oily hair will gradually become more balanced. Dosage according to hair type For fine hair, use 2 to 3 drops on the lengths and ends only. Avoid the roots. Warm slightly between your palms before applying. For oily hair, use 1 to 2 drops on the lengths and ends. Focus on dry areas. For thick or very long hair, use 4 to 5 drops. You can apply it to the entire head of hair. The important thing is to distribute it evenly and not to overload. Start with a small amount and gradually increase as needed. Every head of hair is different. You will quickly find the ideal amount. create a shield against UV rays and pollution, making them a practical ally for busy days.

Does this serum really protect against heat and UV rays? How does this protection work?

▼
Heat protection: creating a barrier against heat When you use a hair dryer or straightening iron, the heat damages the hair fiber. It opens the cuticle and oxidizes lipids. This serum creates a protective barrier that absorbs some of the heat before it reaches the fiber. Jojoba oil has a high smoke point, which means it can withstand heat without breaking down. Ceramides strengthen the natural barrier, making the fiber more resistant to heat. Together, they reduce heat damage by 30 to 50%. UV protection: preventing oxidation UV rays oxidize the lipids and pigments in your hair. This is why your hair becomes dull and brittle after exposure to the sun. Organic hydrosols contain natural antioxidants that neutralize the free radicals created by UV rays. Jojoba oil also contains natural antioxidants. Together, they create an anti-oxidation barrier that protects your hair from UV damage. If you have colored hair, this protection is crucial for maintaining your color. Combined action: heat + UV This serum protects against heat AND UV rays. It's double protection. You can use a hair dryer or flat iron without fear. You can also expose yourself to the sun without damaging your hair. After a few weeks of regular use, your hair will be visibly stronger and shinier. This is the effect of progressive protection against daily damage.

When should I apply this serum? In the morning or at night? How many times a day?

▼
The best time: in the morning before styling Apply this serum in the morning after shampooing and before styling. Your hair should still be damp or slightly damp. Apply 2 to 5 drops depending on your hair type. Warm slightly between your palms. Distribute evenly over the lengths and ends. No rinsing required. You can style your hair immediately afterwards. The serum creates a protective barrier against the heat of the hair dryer or flat iron. It also protects against pollution and UV rays throughout the day. Use as a touch-up in the afternoon If your hair becomes coarse or dull during the day, you can apply a small amount (1 to 2 drops) to the lengths and ends. This revives shine and smooths the hair without weighing it down. This is particularly useful if you have used a straightening iron or been exposed to the sun. Recommended frequency Use this serum daily in the morning. It is a light treatment that can be used every day without any problems. You can also use it in the evening if your hair is very dry, but this is not necessary. Morning use is sufficient for optimal protection and nourishment. After a few weeks of regular use, your hair will be visibly shinier, smoother, and stronger. This is the effect of daily protection and nourishment.

Why is this serum better than a traditional serum? What is the real difference?

▼
The key difference: organic jojoba oil vs. mineral oils Conventional serums often contain mineral oils (paraffin, silicones) that remain on the surface and create a greasy film. This serum contains organic jojoba oil that penetrates the fiber and nourishes it from within. Mineral oils suffocate the fiber and prevent moisture from penetrating. Jojoba oil allows the fiber to breathe and moisture to penetrate. This is a fundamental difference. Ceramides: true repair Conventional serums do not contain enough ceramides. This serum is rich in ceramides. Ceramides rebuild the damaged lipid barrier. Without ceramides, you are only temporarily masking the problem. With ceramides, you repair the problem at its source. This is why the results of this serum are more long-lasting. Cationic hyaluronic acid: deep hydration Conventional serums contain conventional hyaluronic acid, which hydrates the surface. This serum contains cationic hyaluronic acid, which penetrates deeply and binds to the fiber. Hydration lasts longer. Organic hydrosols: real nutrition vs. inert water. Conventional serums contain a lot of inert water. This serum contains 100% active organic hydrosols (Damask rose, chamomile, orange blossom). These hydrosols contain aromatic molecules, minerals, and antioxidants that provide real nutrition. Clean composition vs. traditional serums 98% natural ingredients, free from silicones, parabens, and sulfates. Conventional serums often contain silicones that suffocate the hair fiber in the long term. This serum respects your hair fiber while strengthening it. A conventional serum costs €15-30 and lasts 1 month. This serum is more expensive but lasts 2 to 3 months and offers 3 times better results. The cost per use is comparable, but the effectiveness is much higher. After one use, you will feel the difference. Your hair will be smoother and shinier. After 2 to 3 weeks, the transformation will be visible. After 4 weeks, your hair will be noticeably stronger, shinier, and healthier. That's why this serum is superior to classic serums.
