From cult-classic argan oil to subversive #AltHair dye jobs, the next era of beauty is being scripted in 15-second clips. Here’s what’s actually worth your R&D budget — and what to leave on the moodboard.
The numbers tell the story before the strategy decks do: #HairDye has crossed 17.4 billion cumulative views, #DHTBlocker has reached 8.6 billion, and #AltHair is growing at 83% year-over-year. Behind those figures is a clearer signal for anyone building a hair or bodycare range — consumers are simultaneously reviving heritage ingredients (argan oil), normalising once-taboo skin concerns (cellulite, keratosis pilaris, ingrown hair), and reclaiming hair as their primary identity canvas. Below are eight hashtags that defined the March–April 2026 conversation on TikTok, grouped into three practical buckets: core categories worth defending, early-stage bets worth piloting, and emerging signals worth watching. Each entry includes what’s driving the conversation, who’s already winning, and what to do about it.
The Core Categories — Defend and Optimise
These are the heritage performers holding the top of the charts this cycle. They have scale, staying power and clear consumer intent. The smartest move isn’t reinvention — it’s continual product refinement and tighter storytelling.
1. #HairDye — 17.4 billion views
If there is a single hashtag that anchors the entire category, this is it. With 17.4 billion cumulative views, #HairDye is the gravitational centre of TikTok beauty — the foundational topic from which subcultures like #AltHair, #PeekabooHair and #StripeyHair orbit. Hair colour is one of the few categories where consumer behaviour is simultaneously self-expressive, ritualistic and replenishable — a rare commercial trifecta.
The real opportunity now is bond-supporting, lower-commitment formats. Circana’s 2025 prestige beauty data shows at-home hair colour and colour-care holding double-digit growth in the US, outpacing several skincare subcategories. Brands like Madison Reed, dpHUE and Good Dye Young have built nine-figure businesses precisely by reducing the friction — and the damage — of frequent colour change.
What to do: Lead with bond-builders, colour-depositing conditioners and demi-permanent systems heading into the spring-summer cycle. The winning narrative isn’t “vibrant colour” — it’s “vibrant colour that doesn’t punish you.”
2. #ArganOil — 1.9 billion views
The original cult multitasker is back — and TikTok is treating it like a discovery, not a revival. Creators are deploying argan oil across hair, scalp, nails and body in a single routine, validating the broader rise of “ancestral” beauty and the renewed appetite for desert-origin ingredients. Grand View Research values the global argan oil market at $370 million in 2024, with projected growth above 9% CAGR through 2030 — a quiet but unmistakable signal of category staying power.
The strategic prize lies in provenance and cultural storytelling. Morocco’s emergence as a beauty power centre — already evident in the global success of brands like Kahina Giving Beauty and Josie Maran, which crossed $100 million in retail sales largely on argan — rewards companies that partner equitably with local cooperatives rather than extract the aesthetic.
What to do: Develop cross-category portfolios (hair oil, body lotion, cuticle treatment) anchored by single-origin argan. Lead with provenance-first marketing. This is a slow-burn ingredient with decades of runway — exactly the profile that rewards quiet, sustained investment.
3. #Cellulite — 2.3 billion views
Few hashtags better capture the cultural tension defining bodycare this spring. #Cellulite content on TikTok is currently bifurcated: one camp rejects shame and posts unretouched skin; the other shares lymphatic drainage rituals, gua sha tools and firming serum routines. Both camps are growing. Both want products.
This is the category’s central challenge — and its opportunity. The global cellulite treatment market, valued by Fortune Business Insights at $1.78 billion in 2024, is projected to reach $2.96 billion by 2032. Brands like Sol de Janeiro (acquired by L’Occitane for $450 million in 2021) demonstrated that bodycare scales fastest when it sells sensorial confidence rather than corrective shame.
What to do: Build technical taskers — biomimetic actives that address skin laxity across postpartum, perimenopause and GLP-1-related body change — and pair them with untouched marketing imagery. The brands that win will sell smoother-looking skin without implying current skin is broken.
4. #KeratosisPilaris — 1.29 billion views
Once whispered about in dermatology forums, “KP” has become one of TikTok’s most destigmatised skin concerns — and a fast-emerging shelf category. The hashtag’s 1.29 billion views reflect a generation of consumers who learned the clinical term from creators before ever seeing a dermatologist.
The commercial response has been swift. First Aid Beauty’s KP Bump Eraser is now a Sephora top-20 body SKU, and indie entrants like Nécessaire and Soft Services have launched dedicated KP systems combining lactic acid, urea and niacinamide. Mintel reports that body exfoliation grew 14% year-over-year in the US in 2024, with chemical exfoliants outpacing physical scrubs for the first time.
What to do: Treat KP as the entry point to a broader body-skinification portfolio. Educational content that names the condition without pathologising it will convert better than aspirational visuals — especially as short-sleeve season approaches.
5. #IngrownHair — 798.8 million views
The smallest hashtag in this group signals one of bodycare’s clearest whitespace opportunities: post-hair-removal care. With shaving, waxing, sugaring and laser all coexisting in modern routines, ingrown hairs have become the universal pain point — and the universal commerce opportunity — heading into peak hair-removal season.
Fur, Bushbalm and European Wax Center’s private label have already proven the willingness to pay premium prices for precision treatments. With the global hair removal products market projected by Grand View Research to reach $2.34 billion by 2030, ingrown-hair-specific exfoliating serums and pads represent one of the cleanest line-extension plays in bodycare.
What to do: Launch targeted exfoliating body serums (PHA, BHA, mandelic acid) positioned as routine simplifiers. Bundle with razors, wax kits or at-home laser protocols.
Early-Stage Bets — Pilot Now, Scale Later
These are the trends gaining real velocity over the past two months. Momentum is there; maturity isn’t. Pilot in small volumes; the upside justifies the experimentation budget.
6. #DHTBlocker — 8.6 billion views
The largest emerging trend on this radar is also one of the most clinically charged. DHT (dihydrotestosterone) blocking — long the language of men’s hair loss pharmaceuticals — has been reframed by TikTok creators as a unisex scalp-health ritual. The result: 8.6 billion views and a flood of saw palmetto shampoos, rosemary serums and caffeine-infused scalp tonics flooding creator FYPs.
The market is responding. Nutrafol, acquired by Unilever in 2022, surpassed $200 million in sales by 2023; Vegamour and Divi have built scalp-led businesses on the same demand wave. Fortune Business Insights projects the global hair loss treatment market will hit $14.2 billion by 2028.
What to do: Test scalp-health SKUs with credible actives (rosemary oil, saw palmetto, peptides) and route claims through clinical substantiation. The category is mid-transition from niche to mainstream — and shelf space is still negotiable.
7. #AltHair — 480.3 million views, +83% YoY
The headline growth story of the entire radar. With 83% year-over-year view growth, #AltHair signals a return of subcultural identity — goth, emo, scene, e-girl — channelled through hair as the most accessible form of transformation. Calico, peekaboo and stripey colour blocking dominate the conversation.
This is festival-season catnip, and the timing is critical. With Coachella, Glastonbury and Lollapalooza collectively expected to drive over $1.5 billion in adjacent beauty spend in 2026 (per IMARC Group estimates), brands that can deliver high-impact, low-commitment colour in the next 8–12 weeks will own the moment. Good Dye Young, Arctic Fox and Lime Crime have already built their entire propositions on this consumer.
What to do: Bundle semi-permanent dyes, clip-ins, hair tinsel and bond-builders into festival-ready kits. Lead with creator-driven transformation content rather than polished campaign imagery.
Emerging Signals — Watch Closely
8. #StripeyHair — 271 million views
The youngest entry on the radar and the most aesthetically specific. Stripey hair — contrasting blocks of colour layered through the lengths — has emerged as a Gen Z signature, riding the same youth-subculture current as #AltHair but with a tighter visual identity. At 271 million views, it’s not yet ready for mass investment, but it’s precisely the kind of micro-aesthetic that has graduated from TikTok to runway in the past 24 months (see Miu Miu’s SS25 hair styling and Charli XCX’s Brat-era colour blocking).
What to do: Monitor creator velocity rather than view count. If #StripeyHair sustains its current trajectory through festival season, expect it to graduate into the Test bucket by Q4 2026 — at which point professional salon partnerships and limited-edition colour drops become the logical first moves.
The Bigger Picture: Three Shifts Reshaping the Category
Step back from the individual hashtags and three structural shifts come into focus this cycle — each with direct implications for product roadmaps, sourcing strategy and merchandising plans through 2027.
1. Ingredient provenance is the new luxury cue. #ArganOil’s quiet resurgence isn’t nostalgia — it’s part of a broader consumer migration away from lab-coded actives toward ingredients with a place of origin, a backstory and a human supply chain. NielsenIQ data shows products carrying “single-origin” or geographic-provenance claims grew 22% faster than the broader prestige beauty category in 2024. Expect Moroccan argan, Brazilian cupuaçu, Korean centella and Mediterranean olive squalane to behave less like ingredients and more like vintages.
2. Bodycare is finishing its skinification arc. #Cellulite, #KeratosisPilaris and #IngrownHair are not three separate trends — they are the same trend, expressed across three different square inches of skin. Consumers now expect their body shelf to mirror their face shelf: actives, serums, targeted treatments and clinical-grade language. Euromonitor projects global premium bodycare to grow at 7.8% CAGR through 2028, more than double the rate of mass bodycare. The brands that own this transition will be the ones that resist the temptation to simply “scale up” facial formulas, and instead build body-specific delivery systems for body-specific concerns.
3. Subcultural identity is back — and it’s a product category. #AltHair’s 83% year-over-year growth and #StripeyHair’s emergence aren’t isolated aesthetic moments. They are evidence that Gen Z and younger millennials are reclaiming hair as the most efficient identity signifier available — cheaper than fashion, more reversible than tattoos, more visible than makeup. For brands, this means the next decade of hair colour innovation will be judged less on shade range and more on damage economics: how much expressive transformation can a consumer afford, in both wallet and hair-health terms, before they tap out?
Key Takeaways
The eight hashtags above aren’t a wish list — they’re a workload. For product teams building future ranges right now, the practical sequencing is straightforward: defend the core with sharper formulas and more honest marketing (#HairDye, #ArganOil, #Cellulite, #KeratosisPilaris, #IngrownHair); pilot the next wave with small-batch launches and creator-led seeding (#DHTBlocker, #AltHair); and watch the horizon with the discipline to act only when the data justifies it (#StripeyHair). Underneath all three lies the same structural truth — provenance is the new luxury, bodycare is finishing its skinification arc, and subcultural identity has become a product category in its own right.
