Short hair can be just as versatile as long hair, and Lily Collins has proven it while promoting season 5 Emily in Paris. From TV appearances to red carpet events and interviews, the actress has showcased her sleek bob in multiple ways, sometimes relaxed and effortless, other times sharply polished and ultra-sophisticated.
Yet one hairstyle stands out above the rest: Glass hair. This pin-straight, mirror-like finish, defined by intense shine and zero frizz, has become her signature look this season, elevating even the simplest outfit.
The Stylist-Approved Formula Behind Lily Collins’ Glass Hair
Celebrity hairstylist Gregory Russell, who regularly styles Collins, has revealed the secret behind the look on social media.
For hydration and frizz control, Russell relies on Pureology, a vegan haircare brand formulated to deeply moisturize the hair while maintaining lightness and shine, key for achieving a sleek finish without greasiness.
For styling, he recommends the AirLight Pro dryer by L’Oréal Professionnel, a high-performance tool that uses infrared light technology to help protect the hair fiber while preserving natural moisture. The result is straighter, smoother hair with noticeably enhanced shine.
How to Get the Perfect Straight Hair Finish
To recreate Lily Collins’ sleek style at home, technique matters just as much as products. Always blow-dry hair from roots to ends, directing airflow downward to seal the cuticle.
Once dry, refine the look with a flat iron or a hot air brush. Choose tools with adjustable temperature settings to avoid unnecessary heat damage, and always apply a heat protectant beforehand; this is a non-negotiable step according to professionals.
The Power of the Part
A polished hairstyle depends heavily on a precise part. Use a pointed tail comb to create a clean line and adjust it to your face shape.
A center part, like the one Collins frequently wears, visually elongates rounder faces and creates symmetry. A deep side part flatters oval or elongated face shapes by adding softness and dimension. This small detail makes a major difference in achieving a refined, editorial finish.
The Final Touch for Maximum Shine
To enhance the glass-hair effect, finish with a lightweight hair oil applied only from mid-lengths to ends. This boosts shine without weighing the hair down. Brush through one final time, and the result is smooth, luminous hair worthy of the red carpet.
The takeaway: With the right products, tools, and technique, glass hair isn’t just a celebrity secret; it’s a look you can master at home.
