Why use a hair oil?

Incorporating an oil into your hair routine is no longer an ancestral beauty gesture, but a truly enlightened choice. At a time when science is joining tradition, vegetable oils are establishing themselves as care products in their own right.

Much more than a simple "product", they become tailor-made care elixirs, capable of responding precisely to the varied needs of each hair type.

The targeted benefits of plant oils for the hair fiber

A well-chosen hair oil doesn't weigh hair down: it seals in moisture, restores the lipid barrier and enhances the hair's texture.

Far from comedogenic fats, certain oils - such as avocado oil or broccoli oil - act as deep skin care.

In particular, they allow you to :

• strengthen fiber and prevent split ends thanks to essential fatty acids;
• preserves suppleness and shine without a sticky effect;
• protect against external aggressions (UV, pollution, limescale).

Moisturize the scalp, stimulate growth

What you apply to the roots is just as crucial as what you apply to the lengths. Certain oils - such as castor or mustard - are renowned for their stimulating effect on microcirculation, promoting growth while soothing sensitive scalps.

Hair oil, serum or oil bath: what's the difference?

• The hair serum acts as a finishing touch, often based on silicones (in conventional versions).
• Daily hair oil lightly nourishes and protects.
• The oil bath, on the other hand, is a more intense ritual, to be left on, often before shampooing.

To the question "Is it good to put oil on your hair?", the answer is unambiguous: yes, as long as you choose a quality vegetable oil suited to your hair type, and use it judiciously.

How to choose the right hair oil for your hair type and needs?

The art of choosing the right oil for your hair is not a matter of chance, or a passing trend. It's a personalized, almost intimate process, based on a detailed knowledge of your hair and its real needs.

In beauty as in perfumery, the perfect match between material and nature is the key to excellence.

Which oil for dry hair ?

Dry hair, often dull, rough or brittle, calls for rich, enveloping oils that nourish, moisturize and repair. Among the most renowned:

• Avocado oil: rich in oleic acid, it penetrates the hair fiber and improves elasticity.
• Coconut oil: used for centuries in Asia, it is one of the few oils to penetrate deep into the skin.
• Sweet almond oil: gentle, soothing, suitable for sensitized scalps.
• Argan oil: packed with vitamin E, it protects and regenerates damaged ends.

Which oil for oily hair?

Contrary to popular belief, oil is far from being outlawed. As long as you choose dry, sebum-regulating textures:

• Jojoba oil: its composition is close to that of human sebum, enabling it to naturally regulate its production.
• Black cumin oil: purifying, antioxidant, particularly appreciated by oily scalps.
• Mustard oil: invigorating, it stimulates without suffocating the roots.

Which oil for curly or frizzy hair?

This type of hair requires special attention: nutrition, definition and shine are essential.

• Castor oil: fortifying, it redensifies curls.
• Shea oil: ideal for very dry hair, it restores suppleness and softness.
• Avocado oil: tames frizz and smoothes scales.

Which oil for color-treated hair?

Hair coloring weakens the fiber. The key is to combine protection and radiance:

• Jojoba oil: seals in color without weighing it down.
• Argan oil: preserves pigmentation while strengthening.
• Hibiscus oil: renowned for reviving color and adding mirror-like shine.

Which oil is right for hair growth?

Certain oils are true hair stimulants. They boost scalp circulation, strengthen the roots and limit hair loss.

• Castor oil: essential for denser, faster growth.
• Broccoli oil: little-known, it improves hair structure while stimulating growth.
• Mustard oil: warming, it awakens the hair follicle.
• Rosemary essential oil (diluted): its action on microcirculation has been scientifically documented.

Which oil for which hair type? Recap

Hair type / needs	Recommended oils	Key benefits
Dry hair	Coconut, avocado, sweet almond, argan oil	Nutrition, repair, shine, suppleness

What's the best hair oil? Comparison of the most effective natural oils

There's no such thing as the "best" hair oil in the universal sense. It all depends on the nature of your hair fiber, your scalp, and the effects you're looking for.

It's a bit like choosing a perfume: what enhances one can weigh down another. Experience has taught me that you have to learn to listen to your lengths, to observe how they react to touch, humidity and the seasons.

A well-chosen oil can transform tired hair into a living, supple, luminous substance.

Here is a comparison of the most effective oils according to different criteria:

Vegetable oil	Hair type	Main function	Texture / absorption	Price guide
Avocado	Dry, curly	Intense hydration	Rich, penetrating	€€
Coco	Dry, damaged	Repair, shine	Strong when cold, light	€
Jojoba	Bold, colorful	Regulation, protection	Dry, fluid	€€
Ricin	Fine, brittle	Growth, fortification	Thick, viscous	€
Argan	Colorful, mature	Anti-oxidant, radiance	Medium, quickly absorbed	€€€
Broccoli	Frizzy, thick	Natural smoothing, sheathing	Medium, dry feel	€€

The oil that penetrates best is coconut oil, thanks to its lauric acid content.
The most moisturizing? Avocado, rich in oleic acid and vitamins A, D and E.
The most nourishing is undoubtedly castor oil, to be used diluted.
For silky hair, turn to argan or broccoli, which are true light revelators.

Hair oil bath: how to use it properly?

The oil bath is a ritual I rediscovered while observing Indian and Moroccan hair routines. Applied with care, this gesture transforms the material. It soothes the scalp, nourishes the fiber and acts as a preventive serum against breakage.

Who is this treatment for?

For all those whose hair lacks softness, shine or hold. Particularly recommended for :

• after coloring or bleaching,
• in the event of winter drought,
• for hair exposed to salt, chlorine or UV rays.

How to make an effective oil bath 

A well-executed oil bath provides a deep treatment that restores vitality and radiance to the hair fiber. To reap the full benefits, follow these essential steps:

• Choose thevegetable oil according to your needs (see comparison chart above).
• Apply a few drops, massaging gently with fingertips, to scalp to stimulate microcirculation, then to lengths and ends to repair and protect.
• Leave on for at least 30 minutes, or overnight for very dry or damaged hair.
• Avoid overloading: a dab is more than enough. Too much will weigh down the fiber and make rinsing more difficult.

A successful oil bath begins with measurement. The finesse of the gesture always prevails over the abundance of the product.

Which shampoo eliminates an oil bath?

A gentle yet cleansing shampoo is essential. This is where Madame d'Alexis comes in. Its water-free formula, infused with floral hydrolats and enriched with highly cleansing active ingredients, dissolves oil without aggressing the scalp.

It purifies, leaving the fiber light, supple and perfectly clean.

A personal tip: rinse with lukewarm water, never scalding, and finish with a cool spray to close the scales. This simple gesture enhances hair's natural radiance.

Product focus: Madame d'Alexis hair oils

A hair oil inspired by facial care

At Madame d'Alexis, the line between hair care and high-cosmetic beauty rituals is blurred. Here, hair oil is not just a product - it's a formulation conceived with the same refinement as the most demanding face serums.

What sets this oil apart? An exemplary composition:

• 97 to 99% ingredients of natural origin,
• no animal cruelty,
• zero water added.

Water is replaced by noble organic hydrolats: Damask Rose, Chamomile Matricaria and Orange Blossom, all recognized for their soothing, antioxidant and softening properties.

This choice is not insignificant: in hair cosmetics, effectiveness begins with the quality of the base.

Why it is suitable for all hair problems

Each Madame d'Alexis oil is designed as a targeted yet universal response.

• For dry hair, it intensely nourishes without weighing down, thanks to its richness in essential fatty acids.
• On a sensitive scalp, it soothes, balances and restores the skin microbiome thanks to prebiotics.
• For fine hair, it offers shine and hold, without greasy film or heavy effect.

Personally, I use it in the morning, before drying my hair. Just a few drops are enough. The subtle, botanical fragrance transforms this gesture into a moment of sensory care.

Recommended routine

This oil can be integrated into any routine:

• As an oil bath, before shampooing, for deep hair care.
• Apply daily to damp or dry hair to tame frizz or protect lengths.
• As a finishing touch, to smooth fiber and enhance natural shine.

Its fine texture, delicate plant fragrance and silky feel make it a must-have for elegantly groomed hair.

Mistakes to avoid with hair oils

Even the best oils require rigor and knowledge. When it comes to hair care, luxury is in the detail. Here's what to avoid:

• Too much product: a well-chosen oil should be used sparingly. Too much will saturate the fiber, weigh it down and make rinsing more difficult.
• Use of unsuitable oils: pure castor oil is too thick to be used on its own. Some comedogenic oils can irritate fragile scalps.
• Confusing vegetable oil with mineral oil: petrochemical oils (found in many conventional products) don't nourish - they coat without penetrating. In the long term, they asphyxiate the fiber.
• Apply at the wrong time: for oily hair, use oil as a pre-shampoo treatment. On color-treated hair, use after washing to protect color.

Respecting these principles guarantees the nobility and effectiveness of our hair oil.

Frequently asked questions about hair oils

Hair oil is both ancient in its use and modern in its formulation. But even when it's natural, it raises many questions. Here are the answers to the most common questions - precise, practical and validated by experience.

Can I put oil on my hair every day?

Yes, but it all depends on the type of oil, hair type and dosage. On dry hair, a few drops of a light oil (jojoba, argan, grapeseed) applied daily to the ends can restore shine and softness.

On oily hair, on the other hand, a daily application would unnecessarily weigh down the fiber. Better to opt for a weekly treatment.

Which oil is right for my scalp?

Sensitive scalps will appreciate jojoba or chamomile oil, which soothe and regulate. To stimulate growth or combat hair loss, opt for mustard or castor oil, to be applied with gentle massages. Once again, it's all about listening carefully to your scalp.

What oil should I avoid putting on my hair?

Avoid mineral oils (derived from petrochemicals): they form an occlusive film with no nourishing benefits. Similarly, pure castor oil is too thick to be used on its own. It is best combined with a more fluid oil such as jojoba or avocado.

Do dermatologists recommend the use of hair oils?

Yes, as long as you choose pure, cold-pressed plant oils suited to your scalp. They are particularly useful for relieving itching, dry dandruff or supporting the hydrolipidic barrier.

Which oil for dry ends?

Argan oil is a classic. It protects, softens and nourishes without greasing. Avocado or broccoli oil also work well to close scales and prevent split ends.

When should you use an oil in your hair routine?

One oil fits all:

• before shampooing (as an oil bath),
• after washing (as a finish or to seal in moisture),
• or as a one-off treatment, depending on your needs at the time.

Is it necessary to systematically rinse the oil?

No. It all depends on the quantity applied. An oil used in a bath needs to be rinsed thoroughly, while a dab on the tips needs no rinsing at all.

Verdict - Which oil to choose for naturally beautiful hair?

Finding the best oil for your hair is not simply a matter of olfactory preference. It's all about balancing the nature of your hair fiber, your scalp, your objectives (growth, nutrition, shine...) and even the seasons.

In winter, fiber needs more fat. In summer, it needs protection and lightness.

Summary table: ideal oils by need

Hair problems	Ideal oil
Dry or dull hair	Avocado, coconut, argan
Sensitized scalp	Jojoba, chamomile
Greasy hair	Nigella, mustard, jojoba
Loops to redefine	Ricin, shea, broccoli
Decline or slow growth	Ricin, rosemary, mustard
Colored hair	Argan, hibiscus, jojoba
Damaged tips	Broccoli, avocado, argan

Recommendation: use organic, cold-pressed vegetable oils.

It may seem like a detail, but the extraction method changes everything. A cold-pressed oil retains all its active ingredients: vitamins, antioxidants, essential fatty acids. For best results, choose unrefined, unscented and organic oils.

Why add an oil to your hair routine?

Because no mask or conditioner can match the lipid richness of raw plant oil. It seals in moisture, protects against external aggressions, and reveals hair's natural beauty over the long term.
