Silky Hc Black 1 With Oxygen — Uses, Dosage & Benefits

Hair dyes deposit colouring molecules onto the hair shaft. In oxidative systems, dye precursors react with an oxidizing agent (developer/oxygen) to form larger coloured molecules that get trapped in the hair cortex for longer-lasting colour.

For external use only. Perform a patch test 24–48 hours before each use. Wear gloves; mix/use as per label instructions (often with a developer/oxygen), apply evenly to dry hair, leave for the recommended time, then rinse thoroughly and shampoo/condition. Avoid contact with eyes and eyebrows/eyelashes.

Always follow your doctor's prescription. Do not self-medicate.
