How the colour characteristics of hair affect timing for tint development eyebrow and lashes?

Natural Hair Colour

The natural hair colour of a client will affect the timing for tint development for eyebrows and lashes. Lighter hair colours, such as blonde or light brown, will require less time for the tint to develop than darker hair colours, such as black or dark brown. This is because lighter hair colours have less pigment, so they will absorb the tint more quickly and easily.

* Blonde: Lifts the lightest level of any other shade.

* Light Browns: Lifts hair one level. For example light brown to medium brown.

* Dark Browns: Lift up to 2 levels. For example dark brown to light brown.

* Light Red: Lifts and adds tone.

* Red: Lifts light brown hair 2 levels and dark hair 1 level.

* Copper: Lifts and add copper tones.

* Medium Ash Brown: Lifts one level.

* Dark Ash Blonde: Lifts and adds tone.

* Light Ash Blonde: Lifts up to two levels.

Tint Colour Choice

The choice of tint colour will also affect the timing for tint development. For example, a light brown tint will take less time to develop than a dark brown tint. This is because lighter colours contain more hydrogen peroxide, which is the bleaching agent that helps the tint to penetrate the hair shaft.

Eyebrow and Lash Thickness

The thickness of the eyebrows and lashes will also affect the timing for tint development. Thicker eyebrows and lashes will require more time for the tint to penetrate, so they will need to be left on for longer.

As a general guide, tint should be left on for the following times:

* Eyebrows: 10-15 minutes

* Lashes: 5-10 minutes

However, it is important to note that these are just a guide, and the actual timing will vary depending on the individual client. It is always best to test the tint on a small area of skin before applying it to the eyebrows or lashes to ensure that it does not cause any adverse reactions.
