Hair Colour Ratios

October 08, 2017 1 Comment

Natural hair colour can be created by combining Henna, Indigo and Senna (Cassia) in different proportions. Each botanical dye contributes a different natural colour:

• Henna – produces natural red and copper tones.
• Indigo – produces natural blue tones and, when combined with Henna, creates shades from brown to black.
• Senna (Cassia) – produces warm yellow and golden tones.

 

Brown to Black Hair with Grey

If you have brown to black hair with grey areas, the following Henna and Indigo combinations can create different shades:

Natural Hair Dye Mix	Colour Result
2/3 Henna + 1/3 Indigo	Light Brown
1/2 Henna + 1/2 Indigo	Medium Brown
1/3 Henna + 2/3 Indigo	Darker Brown
Henna first, wash out, then apply Indigo	Black

 

Grey Hair

If you have predominantly grey or white hair, the result will be more vibrant because the botanical dyes are applied to a lighter base.

Natural Hair Dye Mix	Colour Result
Henna	Coppery Red
1/2 Henna + 1/2 Senna (Cassia)	Coppery Gold
2/3 Henna + 1/3 Indigo	Light Brown
1/2 Henna + 1/2 Indigo	Medium Brown
1/3 Henna + 2/3 Indigo	Dark Brown
Henna first, wash out, then apply Indigo	Black

 

Red Hair with Grey

If your natural hair is red with grey areas, these combinations can create different shades of red and brown:

Natural Hair Dye Mix	Colour Result
1/2 Henna + 1/2 Senna (Cassia)	Warm Red
2/3 Henna + 1/3 Indigo	Reddish Brown
1/2 Henna + 1/2 Indigo	Brownish Red
1/3 Henna + 2/3 Indigo	Brown
Henna first, wash out, then apply Indigo	Black

 

Blonde Hair with Grey

On blonde or very light hair, Senna (Cassia), Henna and Indigo can produce a wider range of colours:

Natural Hair Dye Mix	Colour Result
Senna (Cassia)	Yellow Highlights
Henna	Red
1/2 Henna + 1/2 Senna (Cassia)	Copper Red
2/3 Henna + 1/3 Indigo	Light Brown
1/2 Henna + 1/2 Indigo	Medium Brown
1/3 Henna + 2/3 Indigo	Dark Brown
Henna first, wash out, then apply Indigo	Black

 

For a Softer, Ashier Henna Tone

For a slightly less warm red tone, add 1 tablespoon of Amla Powder per 50g of Henna. Amla can help soften the warm red tones produced by Henna.

Important: Colour results can vary depending on your natural hair colour, the amount of grey or white hair, hair condition and the proportions used. Always perform a strand test before colouring your hair.
