Oily hair is one of the most frequent and complex conditions to manage in the trichological field. The choice of shampoos for oily hair, in particular, is decisive in daily treatment. But be careful: it is not simply a matter of “degreasing” the skin.
An overly aggressive approach can in fact produce the opposite effect, i.e. a reactive overproduction of sebum. This is also confirmed by Luana, a specialized technician at Unity Beauty, who emphasizes the importance of choosing rebalancing shampoos, not purifying in an absolute sense.
Oily hair: why it gets dirty immediately and what to do to rebalance it
Sebum is a natural element produced by the sebaceous glands of the scalp with the function of protecting the skin and hair shaft. However, in the presence of glandular hyperactivity, this physiological mechanism turns into an obvious aesthetic problem: heavy, greasy and dull hair a few hours after washing.
The key factor is not only how much sebum is produced, but how it is distributed and what condition the skin barrier is in. In some subjects, the glands respond in a hyper-reactive way to internal stimuli (hormonal changes, stress) or external stimuli (unsuitable cleaning products). A delicate but strategic approach is therefore essential, which restores balance without altering the physiology of the skin.
An aspect that should not be underestimated is also the quality of cleansing: washing too frequently with the wrong shampoos worsens the situation, creating a vicious circle that is difficult to break.
Shampoos for oily hair: beware of products that are too aggressive
The most common mistake made with oily hair is to choose an excessively degreasing shampoo, convinced that more “cleanliness” equals a more effective solution. In reality, the use of surfactants that are too strong can be counterproductive, because it deprives the skin of its natural oils, stimulating an even more intense sebaceous response.
Many supermarket or supermarket shampoos contain ingredients such as SLS (Sodium Lauryl Sulfate) or SLES, which can compromise the scalp’s moisture barrier in the long run. This leads to increased sensitization, dehydration and worsening of the oily effect.
Instead, it is preferable to choose a rebalancing shampoo, which does not eliminate sebum but regulates its production and distribution. Among the most effective ingredients in this sense are:
- Zinc PCA, to regulate sebum production
- Nettle extract, with natural sebum-normalizing properties
- White or green clay, to absorb excess sebum without irritating
- Tea tree oil, for its antibacterial and purifying function.

How to use shampoo for oily hair in the correct way to avoid mistakes
Even the best shampoo for oily hair can be ineffective if used the wrong way. Here are some essential guidelines that are often overlooked:
- Washing frequency: maximum 2-3 times a week. Washing too frequently stimulates sebum.
- Quantity of product: one walnut is enough. Too much product increases residues.
- Gentle massage: Do not rub your scalp too vigorously.
- Double wash only if necessary: useful for very oily skin, but to be limited.
- Thorough rinsing: essential to remove any residue.
In addition, it is recommended not to use water that is too hot, which promotes the dilation of the sebaceous glands. Drying should be done at medium temperature, avoiding the hot jet directly on the skin.

Ingredient to look for and avoid in shampoos for oily hair: what the experts say
The care of oily hair also passes through a conscious choice of the INCI. Among the best balancing ingredients are salicylic acid, clays, citrus extracts (grapefruit, lemon) and tea tree oil, all with astringent or purifying properties, useful for regulating sebum production. Other effective active ingredients include zinc pyrithione, useful in case of sebum and dandruff, and AHAs/BHAs (alpha-hydroxy acids) which promote gentle exfoliation of the scalp.
On the contrary, it is advisable to avoid aggressive ingredients such as SLS/SLES, parabens, heavy silicones (dimethicone, cyclopentasiloxane) and mineral oils, which can stress the skin or weigh down the hair. Another item to select with caution is cocamide DEA, which is subject to limitations for potential irritant effects.
The most common false myths about shampoos for oily hair: let’s debunk the legends
In the trichological panorama there are numerous false myths that generate confusion and wrong choices. For example, the idea that washing your hair frequently makes your hair oilier is completely unscientific. In reality, if the scalp requires it, it is the dermatologists themselves who justify targeted daily washing.
Again, dry shampoo is not prohibited, but it cannot exclusively replace traditional washing: prolonged use risks damaging the skin and hair fiber. Finally, many believe that fake “shampoos for damaged/oily hair” have the same effect – false belief: cleansing should prioritize the health of the skin, not just the fiber.
Extra tips to reduce sebum production even without shampoo: natural remedies and good habits
In addition to shampooing, there are several naturally effective strategies to reduce sebum production:
- Use of essential oils such as lemon or peppermint, mixed with baking soda for delicate compresses.
- Care of the brushes, which must be clean and preferably made of wood or natural bristles.
- Stress and nutrition management, key factors in sebaceous regulation.
- Use of gentle peelings on the scalp, to prevent accumulations and promote follicular oxygenation.
These good practices, together with the targeted use of shampoo, promote a more balanced scalp and lighter hair.
