Mythical representations of women, whether Botticelli’s Venus, the Hindu goddess Lakshmi or the maidens of Arthurian legends, often share an unmistakable trait: long, flowing and seemingly unattainable hair. It’s easy to think that such lengths are confined to the realm of mythology, untouched by the harsh reality of split ends and frizz. However, just swipe through TikTok or Instagram to find content creators sporting hair that would rival Rapunzel herself.
Many of these influencers They promise that your hair has grown at a dizzying rate thanks to a specific technique: hair oiling or hair oiling. But, faced with shelves full of exotic formulas and luxury serums, an inevitable question arises: do we really need expensive products or has the ancient secret always been hidden in our kitchen in the form of olive oil?
The resurgence of an ancient ritual. Although the term hair oiling It may sound like a modern invention packaged for Generation Z, the reality is very different. This practice was not born yesterday under the ring of light of a smartphone. Hair oiling is a technique deeply rooted in ayurvedic medicine from India, with Sanskrit texts from more than 5,000 years ago that already recommended infusing hair with natural oils to restore its shine and relax the mind. Likewise, in ancient Egypt also ointments were used based on animal fat or castor oil for similar purposes.
What has changed then? The showcase. He hair oiling In a few months it has gone from being a “legacy trick” to an essential aesthetic ritual. Social media has choreographed it into a highly recognizable scene that includes a slow massage, meticulous application of oils before washing, a warm towel, and blow-drying to an incredibly shiny finish (glossy). Among the avalanche of coconut, argan and jojoba oils, olive oil has begun to reclaim its throne, not only because of its accessibility, but because it has historically been the cornerstone of Mediterranean cosmetics and the basis for extracting the properties of countless medicinal plants.
The science behind the shine. Beyond visual aesthetics, the big question is whether slathering your hair in oil really works. The answer from science is a resounding yes, although with important nuances.
Rocío Lajarín, doctor in Pharmacy and CEO of Alma Secret, explains in GQ that hair is made up of 90% proteins, mainly keratin. “When we use oils with structural affinity, we manage to reduce protein loss and reinforce the resistance of the hair shaft,” he says. The portal Healthline adds that regular oiling reduces “hygral fatigue” (the repetitive swelling and drying of the hair fiber when wet), acting as a cement that protects the cuticles.
If we focus on “liquid gold”, clinical studies support its many benefits:
- Deep hydration and elasticity: An investigation of the Journal of Cosmetic Science demonstrates how olive oil It penetrates the hair fiber thanks to its high content of essential fatty acids, significantly improving hydration and resistance to breakage.
- A cocktail of vitamins: Virgin olive oil rejuvenates hair because it contains vitamin E, vitamin C (which stimulates collagen formation) and vitamin A (enhancers cell regeneration).
- Shield against damage and the sun: The International Journal of Trichology emphasizes that extra virgin olive oil contains hydroxytyrosol, a polyphenol that fights free radicals and cellular damage induced by UV-A rays. In addition, it is highly effective in reducing damage after subjecting hair to chemical processes such as dyes.
- Antifungal action: The same International Journal of Trichology points out that olive oil has an inhibitory influence on fungi that attack hair, such as Microsporum gypseum.
The great debate: Does it make hair grow? This is where dermatology collides with internet myths. Dermatologist Andrea Combalia warns in Telva that at hair oiling “Many benefits are being attributed to it that are not real, such as hair growing faster or increasing its density.” Doctors consulted in Cleveland Clinic They agree that growth rate and thickness are predetermined by genetics, age and hormones. Oils prevent breakage (allowing length to be retained), but do not accelerate the growth phase from the follicle.
However, dermatologist Ana Molina contributes in Trends a fascinating fact. It has been observed that the phytoestrogens present in olive oil can have an antiandrogenic effect by inhibiting the enzyme 5-alpha-reductase (which converts testosterone into DHT). Since DHT causes miniaturization of follicles in androgenetic alopecia, “phytoestrogens may help prevent or slow its progression.”
Roots or just tips? This is the point of greatest controversy. Oiling the scalp before washing protects the lipid barrier of the skin against the aggressive surfactants in the shampoo. However, hairdresser Daniel Gil in Marie Claire and Dr. Steven Walker in GQ They are blunt: if you have an oily scalp or suffer from seborrheic dermatitis, you should avoid applying oils directly to the roots.
Dr. Shilpi Khetarpal of the Cleveland Clinic confirms this: if you are prone to dandruff, applying oil can worsen the problem by feeding the fungus Malasseziacausing more inflammation. In these cases, the hair oiling It should be strictly from medium to ends.
A ritual with common sense. At the end of the day, olive oil is not going to rewrite your hair genetics or magically transform you into a Renaissance painting. What science tells us is much more pragmatic and, at the same time, liberating.
The true value of this trend lies in understanding hair care as a ritual that respects our natural hair structure, and not as a compulsive accumulation of synthetic cosmetics. Olive oil is a powerful, accessible and dermatologically endorsed tool to defend our hair from pollution, the heat of straighteners and daily wear and tear. Applied with common sense, the liquid gold of our Mediterranean diet is also confirmed as the best cosmetic in our bathroom.
