A small amount of product is applied to your skin, and you wait 48 hours to check for any irritation or allergy. This step keeps your scalp safe and your colouring experience comfortable.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766160005709\">\n<h3 class=\"schema-faq-question\">When should you shampoo your hair before a colouring appointment?<\/h3>\n<p class=\"schema-faq-answer\">You should shampoo your hair at least 24 hours before your colour session, but avoid washing it immediately beforehand. Slightly &#8216;dirtier&#8217; hair maintains your scalp&#8217;s natural protective oil layer, which acts as a barrier against hair dye chemicals. This helps keep your scalp healthier and the colour looking shinier.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766160005710\">\n<h3 class=\"schema-faq-question\">How can you show your ideal hair colour to your stylist?<\/h3>\n<p class=\"schema-faq-answer\">Bringing a picture is the best way to show your desired hair colour if you&#8217;re unsure how to describe it. Visuals can help your stylist understand exactly what you want. Keep in mind that achieving certain colours, like an icy blonde, may not be possible in one visit depending on your starting hair shade.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766160005711\">\n<h3 class=\"schema-faq-question\">How long should you plan for a major hair colour change?<\/h3>\n<p class=\"schema-faq-answer\">Major colour changes can take a significant amount of time, especially if you&#8217;re going from dark to light shades. Allow enough time for your appointment so your stylist can complete the process thoroughly. Relax and be prepared to stay at the salon for the full process from start to finish.<\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>You&#8217;ve spent hours Googling the hair of your dreams (and finally decided to book something besides a &#8216;trim&#8217;).\u00a0Don&#8217;t\u00a0let that colour go easily.
