FHISummer 2025 is shaping up to be the season of effortless glam and TikTok has the receipts. From ultra-sleek buns to soft, brushed-out waves, the app is overflowing with heat-friendly hair trends that look polished without trying too hard.
This season, it’s all about keeping cool while staying styled. Below, we’re breaking down the three biggest TikTok hair trends of the moment, and how to recreate each look using your favorite FHI Heat tools.
1. The Ultra-Slick Bun
The Trend: Center-parted, pin-straight, and frizz-free. This elevated take on the classic bun is all about control and shine.
How to Get the Look:
Start by blow-drying hair smooth using the Innovator Pro Power Speed Dryer, focusing airflow with the wide concentrator nozzle for maximum direction and sleekness. Flat iron roots and lengths with the Platform Signature Pro Styler to eliminate any texture, then pull hair into a low bun and finish with a smoothing balm or pomade.
2. Soft Waves with a Glow
The Trend: This season’s version of beach waves leans softer, shinier, and a little more refined. Think airy texture with a “glow girl” twist.
How to Get the Look:
Use the Platform Tourmaline Ceramic Curling Iron on large sections for loose, smooth curls. Once cooled, brush through with the UNbrush® Detangling Hair Brush to blend and soften the waves. The result is polished movement that catches the light without looking over-styled.
3. Diffused & Defined Curls
The Trend: Summer 2025 is all about embracing natural texture with a twist. Defined, voluminous curls that still feel soft and effortless are showing up all over TikTok, especially in routines that spotlight curl health and shape.
How to Get the Look:
Start by applying a leave-in conditioner and the Knot UNwinder spray. Then, use the Platform 1900 Nano Lite Pro Dryer with the diffuser attachment to gently dry without disturbing your curl pattern. Work in sections and use low heat + medium airflow to lock in shape while boosting volume at the roots.
Once curls are 90% dry, scrunch gently and let the rest air-dry for natural definition. The result: bouncy, frizz-controlled curls that hold their shape all day with zero crunch.
