To use My Color Oxi Creme Developer (10 / 20 / 30 / 40 Volume) 1000ml, select the appropriate volume based on desired lift: 10 Volume (3%) for tone-on-tone or grey coverage with no lift, 20 Volume (6%) for 1-2 levels of lift or standard dyeing, 30 Volume (9%) for 2-3 levels of lift, or 40 Volume (12%) for 3-4 levels of lift, though 40 Volume should be used cautiously due to potential hair damage. Wear gloves to avoid skin irritation and work in a well-ventilated area. Mix the developer with a compatible permanent hair colour or bleach (e.g., My Color or another professional brand) in a non-metallic bowl, following the colour manufacturer’s recommended ratio, typically 1:1 for colour (e.g., 60ml colour + 60ml developer) or 1:2 for bleach (e.g., 30g bleach + 60ml developer). Apply the mixture to dry, unwashed hair using a brush or bottle, starting at the roots for regrowth or full hair for all-over colour, ensuring even coverage. Process for 20-50 minutes, depending on the colour or bleach instructions and desired lift, checking periodically to avoid over-processing. Rinse thoroughly with lukewarm water, shampoo with a post-colour shampoo, and condition to restore moisture. Avoid eye and skin contact, as hydrogen peroxide can cause irritation; if contact occurs, flush with cool water for 15 minutes and seek medical advice. Store the developer in a cool, dry place, away from heat sources, and keep out of reach of children.

What is My Color Oxi Creme Developer used for? It’s a professional creme developer used with permanent hair colour or bleach to activate colour molecules, open the hair cuticle, and achieve lifting, toning, or grey coverage.

What do the volume strengths mean? 10 Volume (3%) offers no lift, ideal for toning or grey coverage; 20 Volume (6%) lifts 1-2 levels; 30 Volume (9%) lifts 2-3 levels; 40 Volume (12%) lifts 3-4 levels but can damage hair if misused.

Is it safe for home use? Designed for professional use, it can be used at home by experienced individuals who follow instructions carefully and perform a patch test to avoid allergic reactions or damage.

Can it be used with any hair colour brand? Yes, it works with most professional permanent hair colours, but optimal results come from using it with My Color or brands specifying similar volume strengths. Always check the colour’s mixing ratio.

How long should I leave it on? Processing time ranges from 20-50 minutes, based on the colour or bleach used and desired lift. Follow the colour manufacturer’s guidelines and monitor to avoid over-processing.

Does it damage hair? Higher volumes (30-40) may cause damage if left on too long or used on fragile hair. Use 10-20 Volume for sensitive scalps or brittle hair, and condition thoroughly after.

Is it vegan or cruelty-free? Vegan or cruelty-free status isn’t explicitly confirmed, as the ingredient list doesn’t clarify animal-derived components. Contact the manufacturer for verification.

What’s the consistency like? It has a thick, creamy texture for easy, drip-free application and smooth mixing, similar to other professional developers like Scruples PURE OXI, ensuring even results.

Can it cover grey hair effectively? Yes, 10 or 20 Volume is ideal for grey coverage, with 20 Volume offering better penetration for stubborn grey hair, delivering vibrant, lasting results.

Does it have a strong smell? It contains hydrogen peroxide, which has a typical chemical odour, but the creamy formula may reduce harshness compared to liquid developers. Work in a ventilated area to minimise discomfort.
