FAQs About Hair Dye
Which type of hair dye is right for me?
Permanent dye is best for long-lasting colour and full grey coverage. Semi-permanent adds a tint without long-term commitment, while temporary colour is great for bold experiments or one-night looks. Choose based on how long you want the colour to last and the effect you're after.
Do I need to prep my hair before colouring?
Yes - clean, product-free hair takes colour better. Avoid deep conditioning right before dyeing, as it can create a barrier. Always do a strand and patch test 48 hours beforehand.
How can I make my hair colour last longer?
Use sulphate-free shampoo, limit heat styling, and avoid over-washing. Colour-protecting products and weekly masks help maintain vibrancy and prevent fading.
