What should I do before applying this cream to avoid an unexpected result or reaction?

As with any hair dye or henna-based product, a patch test before use is advised, especially if your scalp is sensitive. A simple way is to apply a small amount of the cream to a clean area behind the ear or on the inner forearm, leave it as you would on hair, and rinse; if irritation appears, do not use the product on the scalp or hair.

A separate strand test is also practical for colour outcome. Take a small hidden section of hair, apply the Moka cream, process, and rinse to see how the shade develops on your specific base colour and hair condition. This is particularly important if the hair was recently bleached, chemically straightened, or permed, because the source notes the final shade may develop differently on treated hair.

Beyond testing, make sure the hair is clean and dry or as directed by typical home colour use, protect skin around the hairline with a barrier cream or towel, and wear gloves since henna pigment can stain skin and surfaces. The cream format is less messy than powder, but the pigment still adheres to skin and porous materials.
