How-tos

One-phase dyeing

The method for dyeing hair with henna is almost identical to dyeing your hair with other colouring agents. However, a few tips will ensure the best results:

What do we need?

Bowl
Brush
Towel

1st step

Open the package

2nd step

Empty into a bowl

3rd step

Pour the water into a bowl

50°C

Brown and dark shades

60–90°C

4th step

If your skin is sensitive, test the henna on a lock of your hair

Do not apply hot henna on your head

5th step

Colouring

45 minutes to 2 hours

*Reaction time varies: according to your hair type, whether you’ve used chemical dyes or whether you’ve washed your hair with chemical shampoos containing silicones (they make it difficult to dye hair with henna). However, henna dyeing usually takes between 45 minutes to 2 hours.

Two-phase dyeing for gray hair

The resulting shade depends on the color of your hair before you apply the henna. So if you apply henna to hair that’s already dyed, the results will be different to the results of henna on gray hair. Therefore, two-phase dyeing is recommended for dyeing gray hair (Copper replaces peroxide).

6th step

2nd dyeing

After 30–60 minutes you have your chosen color shade

*Alternatively, you can colour your hair twice with the same shade—for example, 2× black or light brown. However, we recommend a base of our COPPER colour prior to dyeing gray hair.

TIP: The colour reacts faster if you warm the henna mixture on your head with a hairdryer.

FAQ (Frequently asked questions) VOONO

How quickly does the herbal hair colour washes away?

It washes away within 4 weeks after the first colouring. However it never really washes away completely. If you dye your hair on regular basis, the colour will last longer and you only need to colour your hair roots. Dye entire hair legth once per three months.

How do vegetal hair colours work?

They work on the principle of covering the cuticle of the hair. In contrary with chemical hair coulours which penetrate deep into the hair structure.

My hair are dyed by chemical colour. May I use henna?

Yes, you can. Just leave the gap 2–3 weeks after the last colouring. However, we recommend not using silicone and paraben hair products (shampoo, conditioner, hair spray, etc.).

I'm a blonde and I want to go to brown hair, what should I do?

Try your hair first to strawberry to wheat blonde using the Hair of Gauri mask (apply the mask for 45 minutes over the full length). Then apply the brown color. If these two steps were not taken, your hair could go green.

What happens when I put Light brown on blond hair?

Your hair will be reddish or there is a risk of your hair colour turning to green. We do not recommend using Light Brown to blond hair.

If I want to go back to chemical hair coloring, can I?

Yes, you can, any time.

Can be the herbal colour lightened with peroxide?

Yes, with red and red hues, you can use peroxide. With brown and black shades, select the wash bath with vitamin C, not peroxide. Hair could go green.

What is different about VOONO?

VOONO is a Czech brand on a professional level with a customer service. Our herbal colors and hair products are of very high quality and contain fresh herbs.

Why is VOONO ethical?

What should I never do?

Apply a pure indigo to light or gray hair! It will produce an unwanted gray or green shade. We do not recommend applying dark shades to blond hair (Indigo, Soft black and Dark brown - 90 % hair will turn green!). Indigo is suitable for black-haired or in combination with Soft black.

What shampoo and conditioner is suitable with herbal colours?

We recommend VOONO shampoo and conditioner or all that do not contain silicones and parabens.

What if the colour quickly washes out or drops on the neck?

Either the correct procedure is not followed or you have unsuitable hair products. Even natural shampoos sometimes do not fit with herbal colours. Just replace your hair products and the problem should be resolved within 2 weeks. If necessary, contact customer service .

Can the VOONO colours be mixed together?

Yes, they can. The most common combinations are:

Light Brown with Copper

Copper with Orange

Copper with Wine red

Wine red with Orange

Medium brown with Rose brown

Medium brown with Dark brown

Soft black with Dark brown

Soft black with Indigo

Do you have a colorless henna (nourishing)?

Yes, it is called Cassia obovata.

Are VOONO hair colours capable to overlay gray hair?

Yes, if you have less than 30 % gray hair, you can overlay gray hair with only one colouring. If you have more than 30 % gray hair, firstly it is necessary to color the hair roots with the Copper shade. Then apply the selected colour for the whole length of your hair. For more information, see the HOW-TO section on our web page.

How often should I dye my hair with henna or herbal hair colour?

Every second week, but the best is after 4th–5th week (not always the whole length, only roots). The colours are 100% natural, so frequent colouring causes no harm to your health.

How does the Hair of Gauri mask work?

The mask is based on detoxification. Mix it with water and apply to the scalp and hair roots. Full hair application is recommended only if you want to support warm shades. On dark shades, the mask is not recommended for the full length, it could remove or lighten dark pigments.
