What kind of result does the Bitter Chocolate shade give, and can I influence how intense it turns out?

The Bitter Chocolate tone develops into a rich dark brown with warm undertones. It sits in the space between shades: darker and more defined than a soft light brown, but without the hard, graphic effect that pure black can create on brows and lashes. This usually makes it a comfortable match for medium to dark natural colouring — for example, dark blonde to brown or dark hair.

Because this is a two-part oxidative dye that you mix fresh before each application, the colour develops during a short processing time. Within the timing range given in the instructions, you have some control over intensity: leaving the mixture on for less time within that range gives a slightly softer result, while the full recommended time gives the deepest colour. Do not exceed the instructed time — it will not make the result meaningfully darker and only increases the risk of skin irritation.

Two practical points worth knowing before you start:

• Hair colour and texture matter. Fine or lighter hairs pick up colour faster than coarse dark hairs, so if you are unsure, check the result at the shorter end of the timing range first.
• The first minutes can look dramatic. Freshly dyed brows often appear darker immediately after rinsing and typically soften slightly within a day or two as the surface colour washes down.
