Hey there! Here's how to use your Peachy Coral semi - permanent hair colour. First, do a strand and sensitivity test to make sure your hair reacts well. Then, wash your hair with a pH - neutral shampoo and don't use conditioner. Just towel - dry your hair until it's damp. Put on gloves and spread the dye evenly through your hair. Leave it on for 15 to 30 minutes, then rinse until the water runs clear. Remember, this is a semi - permanent dye, so it'll fade with each wash. It usually lasts about 4 to 8 washes, depending on your hair. To keep the colour looking great, use a sulphate - free or colour - friendly shampoo and wash your hair as little as you can. After shampooing, rinse with cold water to lock in the colour. Try to stay out of direct sunlight a lot and avoid swimming in chlorinated water, as these can make the colour fade faster. And always do a patch test before using the product regularly. If you feel any redness or itching, stop using it right away.
