The Stargazer Semi Permanent Hair Dye Colour Rinse is a great way to add a vibrant colour to your hair. This product is available in 70ml bottles in 1, 2 and 4 packs, and comes in the colour Ultra Blue. It is a semi-permanent dye, meaning it will last for several weeks, but will eventually fade away. The dye is easy to use and can be applied directly to the hair. It is also ammonia and peroxide free, making it gentle on the hair and scalp. The Stargazer Semi Permanent Hair Dye Colour Rinse is suitable for all hair types and can be used to create a variety of looks. It is important to follow the instructions carefully and to use protective gloves when applying the dye. This product is ideal for those looking to add a bold colour to their hair without the commitment of a permanent dye.
