Oily scalp: causes, signs, and recommended care
What is known as "oily hair" usually originates in the scalp, not the hair fiber. Understanding this difference is fundamental to avoiding routines that, although well-intentioned, perpetuate the problem.
In many cases, oily roots and dehydrated mid-lengths or ends coexist, especially in long, colored, or heat-exposed hair.
Why Does Your Scalp Get Greasy?
Sebum production is a normal physiological process. The scalp is a highly active skin structure and its sebaceous activity can be modulated by multiple factors:
- Hormonal regulation.
- Stress and lifestyle.
- Temperature and occlusion.
- Use of inappropriate cosmetics.
- Excessively harsh washing.
The cosmetic objective is not to "eliminate all oil," but rather to restore the balance of the skin's microenvironment.
What does an oily scalp need?
A well-designed routine should prioritize:
- Effective yet gentle cleansing.
- Sebum-regulating and soothing active ingredients.
- Light and functional hydration.
- Antioxidant protection.
And don't forget hair length
Oily roots don't mean the hair is properly conditioned. For medium or long hair:
- Always condition mid-lengths and ends.
- Avoid applying to the roots.
- Adjust nourishment according to hair fiber condition (coloration, heat, chemical damage...).

Balancing sebum production without over-stripping the skin is key to restoring freshness, lightness, and volume. Proper cleansing and strategic conditioning make all the difference.
How to properly wash an oily scalp
Cleansing is the cornerstone of skincare, but how it's done is as important as the product used.
Water Temperature: A Critical Detail
Excessively hot water can be counterproductive:
- Increases skin reactivity.
- Can indirectly stimulate sebaceous activity.
- Promotes dehydration of the hair fiber.
Recommendation: wash with lukewarm water, comfortable for the skin. A final rinse that is slightly cooler helps to improve the feeling of lightness.
Washing frequency: busting the myth
Excessively spacing out washes on a clearly oily scalp often worsens the scenario:
- Accumulation of sebum and residue.
- Increased feeling of heaviness.
- Worsened skin comfort.
An oily scalp should be washed frequently, always using gentle formulas in combination with deep cleansing formulas such as H07 Sea Salt Shampoo.
Aggressive detergents are not the solution
Excessively delipidizing shampoos can cause:
- Sebum rebound effect.
- Increased sensitivity.
- Worse cosmetic quality of the hair.
The modern strategy is based on regulating cleansing and skin balance, not over-cleansing.
Washing technique
- Massage gently, without intense friction.
- Focus cleansing on the scalp.
- Rinse thoroughly.
Cosmetic residue is a common cause of hair weighing down and discomfort.

H01 Frequent Use Shampoo: "I love this shampoo. I've noticed that it cleans my scalp very well and my hair has more shine and volume. I like it. I've made a very good purchase."
M. ISABEL (Oily scalp and fine hair)
H07 Sea Salt Shampoo: "THE BEST. I have very long hair (below my hips), slightly dry ends, and a very, very oily scalp. Without this shampoo, I would be condemned to washing it every other day. Before finding it, I had tried everything imaginable… and zero results. I found it through the recommendation of a sales assistant at El Corte Inglés, and since then, I have NEVER used another. I encourage everyone to try it."
BECCA (Very oily scalp and dry hair)
H04 Revitalizing Conditioner: "Perfect for daily use, leaves hair soft and easy to detangle without weighing it down or leaving it heavy"
