The "Manissance" Hits Hair: Why Gen Z Men Are Spending More on Hair Care Than Any Generation Before Them

Your dad used a 2-in-1 shampoo-conditioner combo that doubled as body wash if he was in a hurry. Your granddad used whatever bar of soap was in the shower. You, on the other hand, have a dedicated scalp serum, a sulfate-free shampoo, a bond-building conditioner, and a styling cream you learned about from a 23-year-old on TikTok.

Welcome to the Manissance — the beauty industry's term for the male grooming boom that's turning men's hair care from an afterthought into a serious category. And Gen Z men are leading the charge.

The Numbers Don't Lie

The male grooming market is projected to hit $115.3 billion globally by 2028 and over $67 billion in the U.S. alone by 2026. Men's beauty spending grew 9.9% in 2024, nearly double women's rate of 5.8%. And within that market, hair care and scalp health are among the fastest-growing segments.

The generational split is stark:

• YouGov data shows that men aged 18–34 were twice as likely to consider buying beauty products from Sephora in 2024 compared to 2020
• Mintel reports that 68% of Gen Z males are active skincare users — and the same pattern extends to hair care
• Online retailer Face The Future says over half its customers are now millennial men

This isn't a fringe movement. It's a market shift driven by tens of millions of men who've decided their hair deserves more than a $4 bottle of whatever's on the bottom shelf.

TikTok Changed Everything

If you want to understand why young men suddenly care about hair texture, scalp health, and product ingredients, the answer is a 6-inch screen.

TikTok's role in the male grooming boom can't be overstated. The platform's algorithm doesn't care about gender — it serves content based on engagement. So when men's grooming content started performing, it got pushed to more men, which created more engagement, which created more content. A self-reinforcing cycle.

The content itself has shifted the conversation. Older grooming marketing for men was aspirational and vague: "look your best." TikTok grooming content is specific, instructional, and product-focused: "here's how to train your hair to part differently," "this is what a scalp detox does," "stop using this ingredient if you have this hair type."

The result is a generation of men who know what sulfates are, understand the difference between a matte and a satin finish, and have opinions about hair oil viscosity. Their fathers couldn't have named a hair product brand beyond Brylcreem.

From "Fixing Problems" to Proactive Maintenance

One of the most interesting shifts is attitudinal. Previous generations of men generally engaged with hair care reactively — they'd address a problem (dandruff, thinning) when it became impossible to ignore. Gen Z men are adopting a preventive mindset.

"Clients have gone from worrying about thinning to actually taking action," says Miles Wood-Smith of Murdock London. "From supplements and transplants to targeted routines, men are investing in longer-term solutions."

This mirrors the broader wellness trend that's reshaping health and fitness: the shift from fixing to maintaining. Just as men are now doing skincare in their 20s to prevent issues in their 40s, they're investing in scalp health and hair quality before problems emerge.

Specific behaviors that are now mainstream for younger men:

• Regular scalp care — exfoliating scrubs, scalp serums, and detox treatments that were once salon-exclusive are now part of home routines
• Ingredient awareness — reading labels for sulfates, parabens, and silicones, and choosing products based on hair type rather than marketing
• Supplements — biotin, collagen, and hair-specific vitamin blends have become staples for men in their 20s and 30s
• Professional treatments — scalp health consultations, PRP therapy, and even early-stage hair transplants are no longer taboo for younger men

The Barbershop Is the New Third Place

The evolution isn't just about products — it's about where men go. The traditional barbershop has been reborn as a "third place" (after home and work) where men can invest in themselves in a way that feels natural and judgment-free.

Modern barbershops and men's grooming studios are offering services that would have been unthinkable for the average male customer a decade ago: scalp analysis, hair density assessments, personalized product recommendations, and even facial treatments alongside the haircut.

"The men's grooming market is set to hit over $67 billion by 2026, as more guys get that looking sharp makes you feel unstoppable," notes one industry observer. "Grooming isn't some extra chore or splurge anymore — it's straight-up self-care."

The barbershop visit is no longer a $15 haircut every six weeks. It's a $50–$80 grooming session every three to four weeks that includes a consultation, a scalp treatment, and product education.

The Hairstyle Trends Reflect the Shift

The hairstyles dominating 2026 tell the story too. The trend is toward texture, movement, and low-maintenance looks that still require quality products to achieve.

• Textured crops and natural movement — the "overly polished" era is over, replaced by styles that emphasize natural hair behavior
• Fuller beards paired with shorter cuts — requiring both hair and beard product investment
• Grey blending ("camo") — subtle color treatments that soften grey rather than covering it entirely, reflecting a "natural, not desperate" ethos
• Scalp-forward haircuts — shorter cuts that make scalp health visible, incentivizing men to take care of what's underneath

Every one of these styles depends on product knowledge and routine consistency — exactly the behaviors that Gen Z men have adopted.

What's Driving the Cultural Shift

The Manissance isn't happening in a vacuum. Several forces converged:

Social media democratized grooming knowledge. Information that previously lived behind salon doors or in magazines women bought is now freely available in short-form video.

Celebrity and athlete influence changed the permission structure. When footballers, musicians, and actors openly discuss their grooming routines (or hair transplants), it normalizes the behavior for everyone else.

Wellness culture expanded the definition of masculine self-care. Mental health awareness, fitness culture, and skin care routines created a broader umbrella under which hair care fits comfortably.

The "metrosexual" stigma faded. Younger men simply don't carry the same anxiety about grooming being emasculating. For Gen Z, taking care of your hair is no different from taking care of your body.

The Bottom Line

The 2-in-1 era is over, and it's not coming back. Men's hair care has crossed a threshold from niche to mainstream, driven by a generation that grew up with unlimited access to information and zero patience for "it's just hair, who cares."

Whether this means you need a 7-step hair routine is debatable. But understanding your hair type, using products that actually work for your specific texture, and paying attention to scalp health isn't vanity — it's maintenance. Your hair is one of the first things people notice about you, and treating it well pays visible dividends.

Your dad's 2-in-1 was fine for his era. But you know better now. And your hair knows the difference.
