Billie Eilish has never played it safe with her hair. From icy silver to neon green roots, from midnight black to platinum blonde, she transforms her look as boldly and frequently as her music evolves. You’ve seen the photos scroll past your feed and wondered how she achieves each dramatic change. Maybe you’ve even thought about trying one of her most iconic looks yourself.
This timeline takes you through every major hair transformation Billie has made since her Ocean Eyes days right through to now. You’ll see exactly when each color appeared, how she maintained those vivid shades, and what her latest look reveals about where she’s heading next. Plus, we’ll show you how to recreate her most memorable styles at home with safe, vegan formulas that protect your hair while you experiment with bold new shades.
1. Smart Beauty Billie inspired colours
Every billie eilish hair transformation you’ve admired on stage or screen becomes achievable when you choose the right products. Smart Beauty’s vegan and cruelty-free formulas let you recreate her boldest looks without the salon price tag or harsh chemicals that damage your hair. You get professional results at home with plex-enriched dyes that strengthen your strands while delivering vivid colour.
Why Billie inspired colour works so well at home
Smart Beauty’s semi-permanent and demi-permanent options give you the flexibility to experiment just like Billie does. Your hair stays healthier because these formulas contain plex technology that repairs bonds during colouring. You can switch between shades as often as you want without the commitment or damage of permanent dyes.
Smart Beauty shades that echo her iconic looks
Our Pink & Red collection captures her crimson root phase, while Black & Blue ranges deliver those deep midnight tones she wore for years. Silver & Grey shades recreate her early icy platinum looks, and vibrant greens mirror those unforgettable neon roots. You’ll find exact matches for nearly every phase of her colour journey.
Matching your starting shade to her transformations
Your natural colour determines which shades you can achieve directly. Darker hair needs pre-lightening for pastels and neons, while lighter bases can grab vivid colours immediately. Check our shade guides on each product page to see what results you’ll get from your current tone.
Bleaching and plex care essentials for bold changes
Lifting your hair safely requires quality bleach and proper plex treatment. Smart Beauty’s lightening products include built-in strengtheners that protect your hair structure. You’ll need patience to reach platinum or silver without causing breakage or damage.
Safe vegan friendly colouring for sensitive scalps
Every formula excludes PPD, ammonia, and resorcinol, making them gentle enough for reactive skin. Your scalp won’t burn or itch during processing, and you can colour confidently knowing the ingredients align with ethical beauty standards.
"Professional colour at home means using products that care for your hair as much as they transform it."
2. Ice blonde and silver Ocean Eyes era
The billie eilish hair transformation journey started with a pale, ethereal blonde that captivated fans in her breakthrough video for Ocean Eyes. You saw her sporting silvery white hair that contrasted dramatically with her dark roots and bold fashion choices. This icy look defined her early aesthetic and established her as someone willing to push boundaries with her appearance from the very beginning of her career.
Timeline of her early white and silver hair
Billie first appeared with platinum white hair in late 2016 when Ocean Eyes gained traction online. Throughout 2017 and early 2018, she maintained variations of this pale silver shade, sometimes leaning cooler or warmer depending on toning. The colour stayed consistent across her early performances and music video releases, making it instantly recognisable to her growing fanbase.
What made this icy blonde look so striking
Her pale hair created stunning visual contrast against her signature baggy dark clothing and moody aesthetic. The near-white shade required serious maintenance but photographed beautifully under stage lights and in music videos. You could see how the colour enhanced her youth and vulnerability while projecting an edgy, fearless image that set her apart from other emerging artists.
How to lighten hair safely towards this shade
Reaching platinum requires multiple bleaching sessions if you start with darker hair. Your stylist or home kit needs plex technology to prevent severe damage during the lifting process. Never rush to white in one session or your hair will break off. Space lightening appointments at least two weeks apart and use intensive conditioning treatments between sessions.
Toning and maintenance to keep brass away
Purple shampoo becomes your essential tool for neutralising yellow tones that develop between colour appointments. Your hair needs silver or violet toner every few washes to maintain that cool icy finish. Brass appears quickly on platinum hair, especially if you have hard water or spend time in chlorinated pools.
Styling ideas that showcase the cool tones
Sleek straight hair shows off the pure silver colour without distraction from texture. Your pale shade also looks incredible in loose waves that catch light beautifully. Consider wearing darker clothing to maximise the contrast, just like Billie did during her early performances.
"Platinum hair demands commitment to toning and repair, but the striking result justifies the effort."
3. Blue and teal experimental phase
Between 2018 and 2019, Billie shifted into bold blue territory that ranged from denim to electric teal. You watched this billie eilish hair transformation unfold across red carpets, performances, and social media posts. Her willingness to experiment with vivid blues showed fans that hair colour could change as freely as fashion choices.
Key moments of her denim teal and bright blue hair
Billie debuted softer denim blue shades during late 2018 appearances at award shows and festivals. By early 2019, her hair shifted towards brighter teal and electric blue tones that photographed dramatically under stage lighting. These colours became signature looks during her Don’t Smile at Me tour cycle and appeared in multiple magazine shoots.
How her blue tones shifted across tours and videos
Her blue shades evolved constantly, sometimes appearing cooler and more vibrant, other times fading to muted teal or grey-blue between touch-ups. Tour schedules and performance lighting influenced how the colour looked in different settings. You noticed the variations across music videos where lighting and filters changed the apparent shade significantly.
Semi permanent blues and teals to try at home
Smart Beauty’s Blue & Black collection offers vibrant shades that work brilliantly on pre-lightened hair. Semi-permanent formulas let you experiment without permanent commitment, fading gradually over several weeks. Your results depend on your starting shade, with lighter bases grabbing more intense colour.
Preventing staining on skin fabrics and bathroom
Blue dyes transfer easily onto pillowcases, towels, and light-coloured clothing during the first few washes. Apply petroleum jelly along your hairline and ears before colouring to prevent skin staining. Rinse thoroughly with cool water until the water runs clear, and use dark towels for the first week.
Caring for fading blue and transitioning to new shades
Blue fades fastest of all fashion colours, often shifting to greenish or grey tones within weeks. Your hair needs colour-depositing conditioner to maintain vibrancy between applications. When you’re ready to change, purple or pink shades can overlay faded blue without pre-lightening again.
"Blue hair demands frequent refreshing but rewards you with one of the most striking colour transformations possible."
4. Black hair with neon green roots
This billie eilish hair transformation became her most iconic look and the one fans remember most vividly. You saw her sporting jet black hair with electric neon green roots throughout 2019 and most of 2020, making this combination synonymous with her When We All Fall Asleep, Where Do We Go? era. The striking contrast created an instantly recognisable silhouette that dominated award shows, concert stages, and magazine covers worldwide.
When the neon roots era started and ended
Billie first revealed the black and green combination in early 2019 as she prepared to release her debut album. The look remained consistent through her Grammy sweep in January 2020, though she later admitted wearing a wig for that performance. She kept variations of this style until mid-2021 when she shocked fans with a dramatic shift to platinum blonde.
Why this became her most recognisable look
The neon roots against black length created visual impact that translated perfectly across all media formats. Your eye automatically tracked to those vibrant green sections in photos, videos, and live performances. This look coincided with her biggest commercial success and most intensive touring schedule, cementing the association in popular culture.
Sectioning and placement for vivid neon roots
You need clean horizontal sectioning to achieve this precise root placement. Apply the neon shade only to your top two to three inches of regrowth, keeping crisp lines between the green and black sections. Your application technique determines whether the look appears intentional or messy.
Choosing the right green and black dye pairing
Smart Beauty’s vibrant green shades work brilliantly over pre-lightened roots, while deep black dyes cover your lengths completely. Both formulas need matching longevity so they fade at similar rates. Your green needs extremely high pigment concentration to achieve that electric brightness Billie made famous.
Upkeep root retouch and fade management at home
Neon green fades quickly, requiring touch-ups every two to three weeks to maintain intensity. Your black sections need refreshing less frequently, usually every six to eight weeks. Plan your colour schedule around the green maintenance since that determines your overall appearance.
"Maintaining neon roots demands consistent refreshing, but the dramatic impact justifies the regular upkeep routine."
5. Blonde brunette and back to dark
After years of dark hair and neon roots, Billie shocked the world in March 2021 when she revealed platinum blonde hair across her social media. This billie eilish hair transformation marked a new chapter in her visual identity as she prepared to release Happier Than Ever. You watched her cycle through multiple shades over the following years, each shift reflecting different creative phases and personal evolution.
Platinum blonde reveal and softer vintage styling
She posted the blonde transformation on Instagram, immediately breaking internet records with likes and comments. Your reaction mirrored millions of fans who barely recognised her in that soft golden shade. The colour brought a vintage Hollywood glamour to her aesthetic, completely different from her edgy previous looks.
Move into warm brunette and caramel tones
By December 2021, Billie shifted into rich brunette shades that added warmth to her appearance. These chocolate and caramel tones required less maintenance than platinum and photographed beautifully during her Saturday Night Live performances. Your hair benefits from similar warm shades when you want dramatic change without constant bleaching.
Deep black hair and bold cuts including jellyfish
February 2022 brought her back to jet black, paired with a striking jellyfish haircut featuring shorter face-framing layers. This style created movement and texture while maintaining her signature bold aesthetic. Your own black hair can benefit from similar layering techniques that add dimension without requiring colour.
Red roots and her most recent hair changes
August 2023 saw Billie debut crimson red roots against black lengths at Lollapalooza. This combination referenced her earlier neon roots era while exploring new colour territory. Recent appearances show continued experimentation with red and black pairings that evolve her signature root look.
Switching between light and dark with less damage
Smart Beauty’s plex-enriched formulas let you transition between extremes while protecting your hair structure. Your strands stay healthier when you space dramatic changes appropriately and use strengthening treatments between colours.
"Moving between light and dark shades demands patience and proper products to maintain hair health through each transformation."
