This product is a type of hair dye that offers a semi-permanent solution for those looking to change their hair colour without committing to a long-lasting, permanent result. The ammonia in the dye helps to open up the hair cuticle, allowing the colour to penetrate deeper and last longer than traditional semi-permanent dyes. It is available in a range of vibrant shades and can be applied at home or in a salon. It is important to note that ammonia can be harsh on the hair, so it is advisable to take proper care and conditioning measures to ensure the health and longevity of your locks.
