You certainly are not afraid of a strong look. Lightened to cool, platinum blonde with lightener or heavily foiled highlights, your hair is highly sensitized. It needs to be nourished and protected from yellow tones due to oxidation and sun or heat exposure.
 
Use Bain Ultra-Violet Purple Shampoo once a week until desired tone is reached, followed by Masque Ultra-Violet Purple Hair Mask to maintain shade. Use Bain Lumière Shampoo + Cicaflash Conditioner + Cicaplasme Hair Serum daily for illuminating, hydrating, protecting and priming. Apply Cicaplasme Hair Serum once a week as a nourishing night serum
