Dear Mr. Know-It-All, I've recently fallen into the trend of dip-dyed hair and decided to experiment with strawberry blonde. I did my bleaching and coloring in a salon, but the color washed off quite quickly. As a student, I don't have the cash to keep dishing out at the salon so I want to find some dark blonde demi (yes, demi)-permanent DIY hair color at a reasonable price. I miss my ombre hair! Please help! – Dip-Dyed Doyenne Try Serendipity House in Wan Chai ( Suite 1, 7/F, China Hong Kong Tower, 8-12 Hennessy Rd., Wan Chai ). They carry 27 different shades of ammonia-free demi-permanent colors—including light, medium and dark blondes—that color-corrects as it fades over time (aka blends in, so the disparity isn’t as noticeable). You’ll also have to invest in five additional products (pectin, developer, aroma, scalp wash and cuticle sealer) to carry out all the necessary steps so that your new hair color sticks around.
