Why cold-pressed oils better retain their active properties

Introduction: The extraction method makes all the difference

Not all vegetable oils are created equal. Their quality depends largely on the extraction method used. Cold-pressed oils are obtained without the use of heat or chemical solvents, which preserves all of their active ingredients. As a trichology expert, I will explain why choosing these oils is essential for the health of your scalp and hair.

What is cold-pressed oil?

This is a mechanical extraction method that does not involve raising the temperature, ensuring that the oil's natural components are preserved. It is also referred to as "virgin" or "first cold-pressed" oil.

Why are they better?

1. Vitamin preservation

Fat-soluble vitamins (A, D, E, K) are sensitive to heat. Refined or heated oil loses a large part of its natural vitamins. Cold-pressed oil retains:

• Vitamin E: antioxidant and protective

• Vitamin A: regenerating

• Provitamin D: important for cell growth

2. Rich in natural antioxidants

Antioxidants neutralize free radicals responsible for premature aging of the scalp. They strengthen the skin barrier and prolong the hair growth phase.

3. Better skin tolerance

Cold-pressed oils are purer and less chemically modified. They are therefore:

• Less allergenic

• Better tolerated by sensitive skin

• More effective on reactive scalps

4. Preservation of essential fatty acids

Omega-3, 6, and 9 are fragile. Their molecular structures are altered by heat. Refined oil contains little or no trace of these crucial components. Fatty acids are essential for cell regeneration and skin hydration.

How can you recognize them?

• Label marked "first cold pressing" or "virgin"

• Fluid texture, non-sticky

• Mild, natural scent (no artificial fragrance)

• Slightly cloudy or golden color

Which cold-pressed oils are best for the scalp?

• Castor oil : growth and strengthening

• Black cumin oil : soothing and purifying

• Rice bran oil : regenerating and antioxidant

• Jojoba oil : regulating and protective

• Argan oil : nourishing and restructuring

Recommended frequency and usage

• For scalp massage: 1 to 2 times per week

• As a pre-shampoo or post-wash treatment, depending on the oil chosen

Conclusion: Choosing quality for visible results

Using cold-pressed oil means choosing performance, purity, and respect for your scalp. These rich, unadulterated, and highly active oils offer benefits far superior to refined oils. For a healthy scalp and revitalized hair, always opt for natural... cold-pressed!
