What is the best shampoo for oily hair according to experts?

Finding the best shampoo for oily hair means understanding that the solution lies not in the strength of the wash, but in the balance of the scalp. An effective treatment purifies without stripping, moisturizes without weighing hair down, and respects the skin's microbiome.

Among the new generation of hair care products,Madame d'Alexis Shampoo stands out as an expert and sensory solution to this problem.

Oily hair affects a large portion of the population, regardless of hair type. This imbalance results in heavy, dull roots that quickly become greasy, and a scalp that is often uncomfortable.

The main cause? Overproduction of sebum. This natural lipid film protects the skin, but when produced in excess, it suffocates the scalp and weighs down the hair fiber.

Stress, pollution, excessive washing, and harsh formulas further exacerbate this phenomenon. To restore lightness and shine, it is not enough to simply "degrease": you need to regulate, soothe, and restore balance to the scalp.

The best shampoo for oily hair is therefore one that gently cleanses, respects the skin's microbiome, and rebalances sebum production.

 

 

Why does hair become greasy?

Understanding excess sebum

Sebum is essential: it protects the skin and keeps hair supple. But when it is overproduced, it creates a vicious cycle.

The scalp, damaged by excessive washing, excessively hot water, or irritating surfactants, defends itself by producing even more sebum.

The main causes of oily hair are:

• Excessive washing or the use of harsh shampoos.
• Stress, which stimulates the sebaceous glands.
• Pollution, which clogs the scalp.
• Hormonal imbalances, particularly during adolescence or after pregnancy.

A damaged scalp becomes reactive: it produces more oil to protect itself, creating this "sticky" root effect despite regular washing.

Signs of an unbalanced scalp

• Heavy roots the day after shampooing.
• Loss of volume and hair sticking to the roots.
• Itching, irritation, oily dandruff.
• Dull lengths, lack of lightness and shine.

An oily scalp is not "dirty": it is unbalanced. The right shampoo should therefore purify without stripping, to restore its natural function.

 

What a good shampoo for oily hair must contain

Mild, non-irritating cleansing agents

The basis of a good cleansing product lies in mild surfactants. Powerful sulfates (such as sodium lauryl sulfate) strip away too much oil, creating invisible irritation that stimulates sebum production.

A shampoo for oily hair should:

• Clean effectively without damaging.
• Respect the pH balance of the scalp.
• Light foaming, a sign of a balanced cleansing base.

Gentle formulas preserve the skin barrier and naturally allow for less frequent washing.

Rebalancing and purifying ingredients

An effective shampoo works deep down while maintaining moisture:

• Floral hydrosols (Damask rose, chamomile, orange blossom): soothe and purify.
• Cationic hyaluronic acid: moisturizes without greasiness and restores volume to the roots.
• Prebiotics: restore the scalp's microbiome and limit excessive sebum production.

These active ingredients combine purification, balance, and comfort. They allow the scalp to regulate itself naturally, without any rebound effect.

A lightweight, biodegradable formula

. It should be:

• Free from silicones and parabens, to avoid heavy residue.
• Natural, to minimize irritating reactions.
• Easy to rinse off, completely removing impurities and sebum.

A good shampoo for oily hair does more than just "clean": it helps restore balance to the scalp. This gentle yet effective approach guarantees healthier, lighter, and long-lasting freshness for your hair.

 

 

 

Common mistakes to avoid with oily hair

Washing too often or too little

An oily scalp requires the right balance. Washing it every day may seem like the obvious solution, but in reality it strips the scalp, causing it to produce even more sebum in response.

Conversely, washing too infrequently allows impurities to accumulate, weighing down the roots. In practice, I recommendwashing your hair every 2-3 days, provided you use a gentle, balancing shampoo.

This frequency helps to maintain the skin barrier while controlling sebum production.

Using a shampoo that is unsuitable for your oily hair

Choosing an "intense" product does not necessarily mean "effective" when you have an oily scalp. Common mistakes are:

• a shampoo that is described as "purifying" but is too harsh, containing heavy sulfates or harsh foaming agents
• applying a very rich treatment (mask or oil) to the roots, when it should only be used on the lengths
• Insufficient rinsing or water that is too hot leaves residue and stimulates sebum production
  These bad habits undermine the scalp's natural regulation. Choosing a sulfate-free formula specifically designed for roots prone to oiliness makes a big difference.

Touching your hair too often or overusing dry shampoo

The repeated gesture of running your hand through your hair facilitates the migration of sebum to the root, aggravating the phenomenon of "greasy hair."

Regular use of dry shampoo may seem useful, but when used too frequently or not rinsed out properly, itbuilds up residue that weighs down the scalp and promotes oiliness. Dry shampoo should be used occasionally, rather than as a daily solution.

Good and bad habits to remember for oily hair

 

To do ✅	Avoid ❌
Wash your hair every 2 to 3 days with a gentle, balancing shampoo.	Wash daily with a harsh shampoo that strips the scalp.
Massage the scalp with your fingertips to stimulate circulation.	Scratching with your fingernails or brushing excessively.
Use lukewarm water for rinsing.	Rinsing with water that is too hot stimulates sebum production.
Apply masks and oils only to the lengths.	Apply nourishing treatments to the roots.
Gradually space out washes to re-educate the scalp.	Overuse dry shampoo or styling products between washes.

How to use shampoo for oily hair for long-lasting results

 

Routine for oily hair with Madame d'Alexis products

 

 

The right steps to take when washing your hair to reduce oiliness

To ensure that shampooing becomes a genuine skincare routine rather than a simple automatic gesture, adopt a thoughtful approach. When washing, apply a small amount of product to your wet scalp.

Gently massage with your fingertips: this active contact stimulates microcirculation and helps remove excess sebum. Then rinse thoroughly with lukewarm water, which provides comfort without "shocking" the scalp.

If you feel that the water is not effectively removing the root, repeat the process once: a second shampoo can ensure optimal cleansing, especially in the case of very oily roots.

Personally, I believe that the "quality" of rinsing is just as important as the quality of the product: no cleansing product can work properly if residues remain stuck to the surface.

Classic shampoo or shampoo without added water: what are the differences?

 

Criterion	Classic shampoo	Shampoo with no added water (Madame d’Alexis)
Formula base	Demineralized water (inert)	Active organic floral hydrosols
Concentration of assets	Weak, significant dilution	Highly concentrated, every drop is active
Preservation	Addition of synthetic preservatives	Fewer preservatives needed
Effect on the scalp	May cause irritation or dryness	Soothes, purifies, and provides lasting balance
Environmental impact	Water transportation and waste	Concentrated formula, less packaging, more sustainable

 

Frequency and combination with other treatments Madame d'Alexis

The ideal frequency for washing oily hair is about 2 to 3 times a week, except in very specific circumstances (intense activity, heavy perspiration).

This frequency allows for sufficient time between washes so as not to "stimulate" the sebaceous glands with overly frequent washing. Next, to optimize effectiveness:

• Use the Detoxifying Scrub once a week to remove impurities, excess oil, and stimulate microcirculation.
• Apply the Hydrating Mask only to the lengths and ends: leave it out of the roots to avoid weighing them down.
  This "holistic" approach allows you to use shampoo as a central part of a consistent routine rather than in isolation.

 

 

 

 

The complete routine for long-lasting sebum control

Adopting a regular routine helps to visibly regulate sebum production. Here is the routine I use and recommend:

• Step 1: Scrub → detoxifies the roots, preparing the scalp for cleansing.
• Step 2: Madame d’Alexis Shampoo → cleanses, balances, and purifies without drying out the skin.
• Step 3: Mask → moisturizes the lengths without weighing them down, preserves the freshness of the roots.
• Step 4: Day Serum → apply to lengths for protection, nourishment, and finish.
  This logical sequence ensures that each step is useful, targeted, and contributes to a lasting effect. Without this consistency, you risk "repairing" the roots while overloading the lengths and ultimately repeating the vicious cycle of greasiness.

Adopting a clear routine, choosing the right steps, and following the recommended frequency... This is what allows youto use your shampoo for oily hair as a true regulating treatment, rather than just a quick wash.

My advice: treat your scalp as skin that needs rebalancing, not as hair that needs degreasing.

FAQ – Everything you need to know to choose the right shampoo

What is the best shampoo for oily hair?

The best shampoo for oily hair is one that purifies without stripping and regulates sebum production over the long term.

Rather than looking for a simple "miracle product," opt for a balancing solution formulated with gentle cleansing agents. Madame d'Alexis Shampoo, concentrated in organic floral hydrosols (Damask rose, chamomile, orange blossom), gently cleanses while re-educating the scalp.

Its effectiveness is based on a synergy of natural and prebiotic active ingredients that restore the skin's balance. If we were to rank the top products, it would stand out for its formula with no added water, its tolerance, and its long-lasting results. User reviews confirm its ability to provide effective hair care, suitable for oily roots and sensitive lengths.

What ingredients make for an effective shampoo?

An effective shampoo depends above all on the quality and consistency of its ingredients.

For hair prone to oiliness, choose natural and organic formulas rich in purifying and rebalancing active ingredients:

• White or green clay: absorbs excess sebum without damaging the scalp.
• Plant extracts (nettle, sage, rosemary): stimulate and regulate sebum production.
• Essential oils (lemon, tea tree, lavender): purify and soothe irritation.
• Floral hydrosols: replace water in certain premium formulas such as Madame d'Alexis, to provide active action with every drop.

A good shampoo must therefore combine gentleness, performance, and naturalness to act on both the scalp and the hair fiber.

Which sulfate-free shampoos should you choose?

A sulfate-free shampoo is recommended for all hair types, especially sensitive scalps or those prone to dryness.

Sulfates are powerful foaming agents but they are irritants that weaken the hair fiber. Gentle formulas, such as Madame d'Alexis Shampoo, use plant-based surfactants that are much kinder to the scalp.
They clean effectively without causing irritation or stimulating excessive sebum production.

To choose the best sulfate-free shampoo, opt for natural, balancing formulas rich in botanical active ingredients. They guarantee long-lasting cleanliness and unparalleled lightness, even for sensitive scalps.

What are the risks for pregnant women?

During pregnancy, choosing a safe product becomes essential. Certain chemical ingredients pose a moderate or even significant risk to pregnant women if used frequently.

Natural formulas, free from endocrine disruptors and harsh preservatives, should be preferred.

Madame d'Alexis Shampoo, made with 98% natural ingredients, is a safe solution: free from sulfates, parabens, and silicones, it is suitable for pregnant and breastfeeding women.

For any use during pregnancy, it is still recommended to follow the advice of a healthcare professional, especially in cases of sensitive scalp or significant hormonal reactions.

How to choose a shampoo for colored hair?

A shampoo for colored hair must protect the hair fiber while prolonging the color's shine. The goal is to prevent dullness and dehydration caused by repeated washing.

To make the right choice, opt for sulfate-free formulas enriched with repairing active ingredients:

• Plant-based keratin to strengthen the hair structure.
• Chamomile hydrosol to brighten and soften.
• Cationic hyaluronic acid to maintain hydration without weighing hair down.
  Madame d'Alexis Shampoo is perfectly suited to this hair type: its natural, balanced formula protects color, nourishes the hair fiber, and provides long-lasting shine. It is an effective solution for preserving the beauty of colored hair while respecting the scalp.
