Get the look:
While there are a number of at-home kits available, experts agree it's best to visit your salon to get the bleached look.
Lee says: "I would strongly suggest that no one try and go platinum at home, it is just a recipe for disaster and can go horribly wrong. Also, dying your hair with peroxide is damaging to your hair so put yourself in the hands of a professional to limit the damage."
Harriet Muldoon, head colourist at Blue Tit salon, agrees: "Whenever using chemicals, especially bleach, I would leave it to the professionals, whether the hair is damaged or there are different bands of shades, it isn't worth the risk. At Blue Tit, we advise root top ups every 6-8 weeks to keep your blonde looking fabulous."
In terms of shade, Lee's thinks "the icier the better, with grey tones," and Harriet recommends experimenting with temporary pastel shades as they take to bleached hair best.
For maintaining your blonde, Harriet recommends asking your colourist to use the Olaplex 3-step system, including the aftercare conditioner. We also love Touch Of Silver shampoo and conditioner to keep hair bright and creamy, as well as Lee Stafford's Bleach Blondes Tone Correcting Conditioning Spray.
