Kinder lightening, built into your bleach mix. milk_shake Safe Lightener Complex is a professional additive designed to help protect and support the hair during bleaching and lightening treatments. Added to your bleach mixture, it helps look after the hair's integrity through the lightening process and helps condition it along the way, so hair is better cared for during a service that's inherently demanding on it. It's paraben-free and silicone-free, and this 250ml bottle is the mid-size option, sitting between the 100ml bottle and the 48-vial single-service pack.

What it does for your hair

Lightening lifts out the hair's natural pigment, which is tough on the hair fibre. This additive is designed to help buffer and support the hair during that process, mixed into your bleach, it helps look after the hair's integrity and condition as it lightens, so hair tends to come through the service in better shape. It's an additive rather than a lightener itself, so it works with your existing bleach and developer rather than replacing them. Being paraben- and silicone-free keeps the formula clean. It's worth being clear, though: an additive helps protect, but it can't fully compensate for hair that's already compromised, so proper assessment before the service still matters.

How to use it

For professional use by trained, qualified colourists only. Prepare your bleach mixture (bleach powder + developer) at the appropriate ratio for your target lift, then add Safe Lightener Complex per the milk_shake mixing ratio (previous formats used around 5ml per 30g of bleach mixture, verify the current guidance for this 250ml bottle) and mix thoroughly. Apply and process per your standard lightening technique and timing, then rinse and neutralise as usual. Always carry out an allergy alert test and a strand test, and follow the full manufacturer instructions.

Who it's for

This one's for professional colourists doing regular lightening work who want to help protect the hair as they lift, and who prefer the mid-size bottle format over the small bottle or single-service vials. We've been perfecting colour, blow-dries and styling for clients in Codsall for years, and looking after hair integrity during lightening is one of the most valuable things you can do behind the chair. This range also comes in a 100ml bottle and a 48 x 5ml single-service vial pack.

For professional salon use only, by trained, qualified colourists following the full manufacturer's instructions. This is an additive for use with a bleach mixture, not a standalone product, so the safety considerations of the full lightening service apply. Always carry out a 48-hour allergy alert test and a strand test before every service, allergic reactions can develop with repeated use, not just first use. Do not use on clients who have previously reacted to hair colour or bleach, or on already-compromised/damaged hair without proper assessment (an additive can't fully compensate for existing damage). Wear gloves and an apron, work in a well-ventilated area, and avoid all contact with the eyes, if bleach mixture gets in the eye, rinse immediately with water for at least 15 minutes and seek medical attention. Do not exceed the recommended processing time, do not use during pregnancy without medical clearance, and keep out of reach of children.
