The term "Gold Series" is a common branding for products that contain a gold-like sheen or are part of a premium line. The specific product is a developer, which is an essential component for various chemical treatments.

Here's a breakdown of what the product is and its uses:

Product Type: This is a developer, also known as an oxidizing emulsion or hydrogen peroxide developer. It is a key chemical used in hair coloring, hair bleaching, and skin polishing. It works by opening the hair cuticle, allowing the color or bleach to penetrate and change the hair's pigment.

Hair Coloring: It can lift natural hair color by 1 to 2 levels. It is also the most common developer for covering grey hair.

Hair Bleaching: When mixed with bleach powder, it provides a moderate lift, making it suitable for lightening hair gradually.

"Gold" Series: The "Gold" branding often signifies a formulation that aims to provide a luxurious or improved result. In the context of beauty products in Pakistan, this could mean it contains ingredients that provide a "golden glow" or a more nourishing effect, such as gold extracts, keratin, or other conditioners to protect the hair and skin during the chemical process. Brands like Golden Girl and Moon Touch are known for their "gold" series of developers.
