White hair care: professional coloring and maintenance techniques

Managing white hair requires specific coloring techniques and maintenance products to address the hair's natural porosity and resistance to pigment. Professionals recommend the ‘double base’ technique, which involves mixing a natural or fundamental dye (ending in “.0”) with a desired shade in a 50/50 ratio to ensure color anchoring and prevent the white hair from reappearing quickly.

To avoid harsh appearances, trends like ‘grey blending’ suggest using lighting techniques such as balayage or babylights rather than solid dark colors. Additionally, using 20-volume oxidants is advised to open the hair cuticle effectively without excessive damage.

Maintenance is also critical to prevent yellowing caused by sun exposure and pollution. Purple-pigmented toning shampoos are effective for neutralizing unwanted warm tones. Options range from affordable products like Salon Line’s Meu Liso Prateado to professional lines such as L'Oréal Professionnel’s Silver Expert.
