Hi Tiija! 👋🏼😊
Based on the picture, it looks like your roots are around level 5–6, while the lengths are lightened, which makes it quite challenging to get an even, cool light brown shade throughout the hair without different sections reacting differently ✨
To achieve a neat and long-lasting result at the desired level (6–7), I would recommend having this done by a hairdresser. That way, the roots and lightened lengths can be carefully adjusted with the right pre-pigmentation and toning to ensure the overall look is even and the color doesn’t shift in undertones. Especially since the lengths are already lightened, it’s difficult to get a cool light brown shade at home without the risk of an uneven result or the lengths not taking the pigment as desired 🤍
This way, you get the best conditions for an even and beautiful result in the shade you want 🥰
