How often should I use purple shampoo? This seemingly straightforward question opens a Pandora’s box of considerations. After all, is there a universal frequency applicable to everyone? Should I base my usage on hair type—coarse, fine, or maybe somewhere in between? And what about the present condition of my hair? If I’ve recently undergone a coloring treatment, does that necessitate a modification in my approach? Furthermore, will environmental factors like humidity and exposure to sun affect how often I should indulge in this specialized shampoo? Do I need to contemplate the undertones of my hair color, especially if I’m striving to maintain that coveted platinum or icy blonde hue? And what about the potential consequences of overusing the product? Could frequent applications lead to an undesirable shift in color, or perhaps dryness? Should I consult with a stylist for tailored advice, or rely on trial and error? So many questions abound!
