The key role of jojoba oil in sebum regulation

Introduction: Sebum, between protection and imbalance

Sebum, often demonized, is nevertheless essential for the health of the scalp and hair. Produced by the sebaceous glands, it protects the skin, naturally moisturizes the hair fiber, and acts as a shield against external aggressions. But when it is produced in excess or in insufficient quantities, it becomes a source of imbalance. In this quest for balance, jojoba oil stands out as a natural, effective, and sustainable solution.

Understanding the function of sebum

Sebum is a complex lipid film composed of triglycerides, free fatty acids, waxes, and squalene. It plays several roles:

• Lubricate the surface of the scalp

• Form a protective film against dehydration

• Neutralize microbial and environmental aggressions

Balanced sebum makes hair supple, shiny, and protected. On the other hand, an imbalance results in:

• Oily roots, dry ends

• Oily or dry dandruff

• Itching or irritated scalp

Jojoba oil: a plant-based sebum

Thanks to its wax ester composition, jojoba oil acts as a natural vegetable sebum. It replicates the functions of natural sebum without clogging pores or causing imbalances.

Main actions:

• Rebalance sebum production (excess or deficiency)

• Soothe inflammation caused by unstable sebum

• Restoring consistency to the hydrolipidic film

How it works on oily scalps

In people with oily skin, the sebaceous glands are often overactive. This may be due to:

• Overly aggressive treatments (harsh shampoos)

• An inappropriate routine

• Hormonal imbalances or chronic stress

Regular application of jojoba oil helps to:

• Send a signal of satiety to the sebaceous glands

• Reduce excess sebum production

• Space out your shampoos without discomfort

Result: the scalp becomes more stable, less shiny, and hair stays clean longer.

What about dry scalps?

Conversely, an underproductive scalp may be severely lacking in lipids. This results in:

• Itching, dry dandruff

• Loss of skin elasticity

• Weakened hair growth

By forming a protective barrier similar to that of natural sebum, jojoba oil moisturizes the skin, reduces irritation, and gradually restores natural sebum production.

Application methods for optimal regulation

• As a daily serum : Apply a few drops to clean scalp, massaging gently.

• Pre-shampoo : 30 to 60 minutes before washing, to gently protect and regulate.

• In synergy : Combined with castor oil (stimulation) or rice bran (soothing), it creates comprehensive treatments for all types of imbalances.

• With dermaroller : To enhance absorption and boost deep microcirculation.

Visible results after 3 to 4 weeks

• Less excessive sebum production

• Reduction in itching

• Healthier, better oxygenated scalp

• Lighter, smoother hair

Conclusion: The ally of unstable scalps

Regulating sebum is a key step in any effective hair care strategy. As a "plant-based sebum," jojoba oil is a gentle, intelligent, and effective treatment. Whether combating excess sebum or compensating for a lipid deficiency, it adapts to each need with precision and respect. It is an excellent ally for long-lasting scalp stabilization.
