Niche Breakdown: What’s Trending by Category in September 2025

TikTok thrives on niche communities, and each category brings its own set of hashtags that rise and fall with the seasons. In September 2025, trends are shaped by back-to-school energy, NFL season kickoff, fall aesthetics, and reality TV finales. Here’s how each niche looks this month:

Beauty

TikTok’s beauty space never slows down, and September is a huge month for new launches and seasonal shifts.

• #huda — Huda Kattan’s brand dominates with viral tutorials and September product launches. Creators remix looks using her palettes and lip kits.
• #SkincareTok — As cooler weather arrives, hydrating and repairing skincare routines are trending. Expect barrier creams, oils, and “slugging” content to return.
• #MakeupTransformation — Fall glow-up edits are everywhere, from back-to-school looks to Halloween costume previews.

Why it matters: Beauty hashtags continue to drive both virality and long-tail authority because they’re evergreen with seasonal twists.

Sports

September is one of the biggest months for sports content, thanks to the NFL kickoff.

• #traviskelce — Blending celebrity culture with football, Kelce dominates TikTok again in 2025.
• #GameDayTok — Tailgate videos, stadium highlights, and game-day outfits trend every weekend.
• #FantasyFootball2025 — Fans love ranting about their fantasy teams, creating a mix of comedy and genuine advice.

Why it matters: Sports hashtags aren’t just for fans — they’re cultural moments that crossover into memes, lifestyle, and even fashion.

Travel

Fall brings unique opportunities for travel creators.

• #FallTravel — Cozy road trips, cabin getaways, and scenic drives with autumn leaves are dominating reels.
• #Europe2025 — Study abroad students flood TikTok with vlogs, from Paris bakeries to Barcelona nightlife.
• #WeekendGetaway — Budget-conscious Gen Z users share short, affordable trips, making this hashtag highly relatable.

Why it matters: Travel hashtags thrive in September because they tie into lifestyle aspirations — cozy fall vibes, budget tips, and wanderlust edits.

Food

TikTok’s food niche always spikes with the seasons, and fall content is unmatched.

• #pumpkinseason — From pumpkin spice lattes to pumpkin pie hacks, this is the month’s defining food tag.
• #Starbucks — Starbucks’ fall menu always drives UGC, with creators reviewing drinks, sharing hacks, and recreating recipes at home.
• #ComfortFoodTok — Slow cooker stews, baked pastas, and cozy recipes trend as cooler weather hits.

Why it matters: Seasonal food hashtags not only drive engagement but also overlap with brand-driven trends (like Starbucks) — perfect for creators and businesses.

Pets

Pet content remains one of TikTok’s most consistent niches, but in September, it takes on a seasonal twist.

• #DogTok — Previews of dog Halloween costumes are starting early, adding humor and cuteness.
• #CatTok — Cats knocking over pumpkins or climbing fall décor dominate the humor side of TikTok.
• #PetCareTips — Fall-related safety content (pumpkin spice toxicity, colder-weather prep) is trending in educational corners of PetTok.

Why it matters: Pet hashtags are evergreen but adaptable, and seasonal trends give them an extra boost.

Entertainment

Reality TV, streaming, and new fall shows dominate TikTok’s entertainment space.

• #loveisland / #loveislandreunion — Reunions spark new memes, edits, and commentary clips.
• #NetflixTok — September’s big streaming releases are trending — from thrillers to romcoms.
• #MovieTok — Fall premieres bring reviews, cosplay, and creative edits.

Why it matters: Entertainment hashtags are often time-sensitive but viral-heavy, perfect for quick bursts of visibility.

Each niche is moving in its own direction, but seasonality and pop culture dominate September 2025. Creators who balance timely hashtags (pumpkinseason, loveisland) with evergreen niche tags (DogTok, SkincareTok) can maximize both short-term virality and long-term discoverability.

Which Hashtags Are Already Fading Out

Not every hashtag that trended in August or early September will stay relevant through the month. Some hashtags peak quickly and then lose steam as TikTok’s attention shifts. Here are a few that are already fading out in September 2025:

❌ #BackToSchool

Exploded in late August as students shared shopping hauls, outfit inspo, and move-in vlogs. Now slowing down as routines settle in and the novelty wears off.

❌ #SummerVibes

Seasonal hashtags naturally decline as the focus shifts to fall. Pool parties, beach trips, and summer edits are replaced by pumpkin spice and cozy content.

❌ #AugustDrops

Product launches and limited-edition collabs in August kept this tag active, but most of those campaigns have ended.

❌ #VacationMode

Big summer travel hashtags taper off in September. Fall travel is in, but general “vacation mode” content is losing traction.

❌ #FestivalSeason

With major summer festivals over, this hashtag is dropping in usage until the winter festival cycle starts.

TikTok trends move fast — using hashtags that are already fading out won’t hurt your account, but it also won’t help you reach new audiences. Instead, focus on seasonal and timely hashtags that are climbing in September (like #pumpkinseason, #FallTravel, and #loveislandreunion) to stay relevant.

How to Spot Upcoming Hashtags Before They Peak

One of the biggest advantages on TikTok isn’t just using hashtags that are already trending — it’s getting in early before they explode. Creators who jump on a hashtag while it’s still gaining traction can ride the wave of visibility and become one of the top videos associated with that tag. Here’s how to spot them:

1. Watch TikTok’s “For You” Page Closely

• TikTok often starts seeding new hashtags into the FYP before they hit the Trending tab.
• If you notice the same new hashtag appearing across different videos in your feed, it’s a sign the algorithm is testing it.

Pro Tip: Keep a personal note or Google Doc of hashtags you spot repeating. If you see the same one 3–4 times in a day, use it ASAP.

2. Monitor the TikTok “Trending” Tab Daily

• The Trending tab shows hashtags just as they start rising.
• Look for hashtags with moderate usage counts (10K–50K videos) — these are still early enough to catch before they get oversaturated.

Pro Tip: Use them within 24–48 hours of noticing growth for the best chance of getting early visibility.

3. Track Seasonal & Cultural Events

• Hashtags tied to events always trend, but early adopters gain the most traction.
• Examples in September 2025:
  • • #PumpkinSeason → peaks every fall, but early posts in late August or early September perform best.
    • #NFLKickoff → starts trending with the season launch, but being among the first ensures higher placement.

Pro Tip: Plan a content calendar that aligns with upcoming events and holidays (Halloween, Thanksgiving, etc.) and prep content before hashtags hit peak.

4. Pair Hashtags with Emerging Sounds

• Many viral hashtags rise because they’re tied to trending sounds.
• When you notice a sound starting to spike, check if creators are pairing it with a hashtag — often the two climb together.

Pro Tip: Search the sound’s usage and scroll captions to find which hashtags creators are attaching.

5. Watch Micro-Niche Communities

• Smaller communities (e.g., #StudyTok, #BookTok, #FitnessTok) often birth hashtags before they go mainstream.
• What starts as niche often becomes the next viral wave when the broader TikTok audience catches on.

Pro Tip: Follow top creators in your niche and notice new hashtags they’re experimenting with.

6. Use External Tools for Early Insights

• Tools like TikTok Creative Center, TrendTok app, or Exolyt show hashtags before they fully break out.
• Look for hashtags marked with “Rising” or “Low competition” signals.

Pro Tip: Prioritize hashtags that match your content style — not every trending tag is worth using if it doesn’t fit your niche.

The secret to spotting hashtags before they peak is a mix of daily observation + proactive planning. Don’t wait for TikTok to tell you what’s trending — stay ahead by watching the FYP, leveraging seasonal cues, and monitoring niche communities. Being early is what gets your video pinned to the top of a hashtag page, where the real traffic flows.

Quick Creator Tips: Rotate, Test, Track

Using trending hashtags isn’t just about copying what everyone else is doing — it’s about strategically experimenting and refining your approach. Here are actionable tips every creator can apply in September 2025 to maximize results:

1. Rotate Hashtag Sets Regularly

• Don’t paste the same block of hashtags on every video. TikTok may see this as repetitive or spammy.
• Instead, prepare 2–3 hashtag variations tailored to different themes of your content (e.g., beauty, lifestyle, entertainment).
• Example:
  • Set A (Beauty): #huda #MakeupTransformation #SkincareTok
  • Set B (Seasonal): #pumpkinseason #FallVibes #Starbucks
  • Set C (Entertainment): #LoveIslandUSA #NetflixTok #MovieTok

Pro Tip: Rotate sets across posts in the same week to keep TikTok guessing and your audience engaged.

2. Test Trending + Evergreen Mix

• Pair trending hashtags (short-term visibility) with evergreen niche hashtags (long-term discoverability).
• Example: A fall makeup tutorial could combine:
  • • Trending: #pumpkinseason
    • Evergreen: #MakeupTok #BeautyTips
• This way, you ride the seasonal hype while staying searchable year-round.

Pro Tip: Always ensure trending hashtags fit your content — forced tags can confuse the algorithm.

3. Track Performance Weekly

• Use TikTok Analytics to see which hashtags drive the most impressions.
• Look at reach, engagement, and FYP traffic sources to measure impact.
• Example: If #pumpkinseason drove 30% of impressions on one video, double down on it for similar content while it’s still hot.

Pro Tip: Keep a simple tracker (Excel or Notion) logging which hashtags perform best for your account.

4. Don’t Overload — Less Is More

• Stick to the 4–7 hashtag sweet spot. More than 10 looks spammy and dilutes relevance.
• Example: A caption with five hashtags feels intentional; one with 20 looks desperate.

Pro Tip: Place hashtags after your main caption to keep it readable and clean.

5. Use Branded Hashtags for Authority

• Always include at least one branded tag (e.g., #SMMNutTips) to build long-term recognition.
• Over time, this helps your community rally around your brand and boosts credibility.

6. Stay Agile With Updates

• TikTok’s trending cycle is fast. A hashtag hot today may be irrelevant in 2 weeks.
• Revisit your hashtag sets weekly, and don’t hesitate to swap out fading ones.

Pro Tip: Save time by batching content creation but update captions with fresh hashtags before posting.

Creators who succeed with hashtags in 2025 aren’t the ones who blindly follow trends — they’re the ones who rotate smartly, test combinations, and track results. Treat hashtags as a flexible toolkit, not a one-size-fits-all formula.
