Why the Hair Oil Market Is Bigger Than You Think

One in Four Adults Oils Their Hair Regularly — and a Global Industry Is Built Around It

Hair oiling is one of the oldest grooming rituals in the world, practised for centuries across South Asia, the Middle East, and North Africa long before it became a commercial category. What has changed is the scale. According to YouGov, women are nearly four times more likely than men to oil their hair regularly, and the practice is now crossing cultural boundaries at a pace driven by wellness awareness, natural ingredient trends, and social media. The Hair Oil Market has grown from a regionally concentrated category into a globally competitive segment worth nearly six billion dollars — and the formulation innovation happening within it rivals anything in mainstream skincare. The Market.us Hair Oil Market Report, 2025 maps the full segment breakdown, regional forecasts, and competitive positioning across this category.

Why Ancient Ritual Became a Modern Industry

The resurgence of hair oiling in Western markets tracks almost precisely with two broader shifts: the natural hair movement, which encouraged consumers with textured or chemically processed hair to return to oil-based care, and the rise of scalp health as a mainstream concern. Dermatologists who once focused almost entirely on skin barrier function have increasingly turned attention to the scalp as an extension of that same system, and their recommendations have sent consumers toward cold-pressed oils with documented efficacy.

Coconut oil leads the category with 43.8% of type-based market share, valued for its ability to penetrate the hair shaft and reduce protein loss — a benefit backed by peer-reviewed research. Castor oil follows closely for therapeutic use, particularly in scalp circulation and hair growth applications. What was once grandmother's advice has become a clinical recommendation, and that shift has given the category a credibility it previously lacked in Western retail.

The Formulation Race

What distinguishes today's category from a decade ago is the sophistication of product development. Early hair oils competed almost entirely on ingredient origin — this coconut oil from Kerala, that argan oil from Morocco. The current generation competes on formulation architecture: how oils are combined, what actives are blended in, and how texture and absorption are engineered for modern consumer preferences.

The single biggest challenge the category faced was texture. Traditional oils — effective as they are — left hair greasy and required time to absorb, alienating urban consumers with fast-paced routines. Brands that solved this through lightweight blending and hybrid oil-serum formats unlocked an entirely new consumer base. Published figures on the Hair Oil Market size show herbal formulations now holding 48.5% of segment share, reflecting how strongly consumers have responded to clean-label, plant-derived positioning alongside these texture improvements.

The Social Media Effect

No personal care category has benefited more directly from short-form video than hair oil. TikTok scalp massage tutorials, oiling routine videos, and before-and-after transformation content have introduced practices like pre-shampoo oil treatments and overnight oiling to audiences who had never considered them. The viral reach of these formats compressed what might have taken a decade of retail adoption into a matter of months.

Onion oil illustrates this perfectly. Previously a niche Ayurvedic ingredient, it became a mainstream search term almost overnight after viral posts attributed hair regrowth results to it. Brands with onion oil already in their portfolios saw inventory clear rapidly. Those without scrambled to launch. Content first, retail second — that is how discovery in this category now works.

Where the Category Goes From Here

Asia Pacific currently holds 48.3% of global market share, anchored by deeply embedded cultural practices across India, Indonesia, and the Philippines. The fastest growth story, however, is in North America and Europe, where the category is being built essentially from scratch among consumers for whom hair oiling was never a default habit. Brands that understand the educational component of that market entry — explaining why to oil, not just which oil to choose — are finding the strongest traction.

Sustainability is also becoming a genuine differentiator. Consumers paying premium prices for argan and marula oils are asking serious questions about sourcing, fair trade certification, and packaging. Brands with credible answers are building the kind of loyalty that sustains a category through trend cycles rather than simply riding one.
