Does Henna Cover Gray Hair? Facts and Tips

Yes, well-chosen henna covers grey hair – although it requires the right approach. In the case of light or grey hair, the two-step method works best: first apply pure henna (Lawsonia inermis), and after washing it off – indigo or a plant dye in a chosen shade of brown or black.

How to achieve the best effect?

Choose high-quality henna (e.g. from the Sattva collection with the Ecocert Cosmos Natural certificate)
Do a streak test
Henna regularly – each application deepens the effect

Henna for hair and color durability – what is worth knowing?

Henna is not a chemical dye. It does not open the hair cuticles, but combines with keratin, permanently dyeing the hair structure. Importantly, the color does not wash out, and with each subsequent henna application it gains depth and intensity.

How to preserve the color after henna?

Do not wash your hair with shampoo for 48 hours after hennaing.
Use mild, natural shampoos without SLS
Oil your hair regularly – e.g. with amla, coconut or argan oil

Post-henna care – how to care for your hair after dyeing it with henna?

Natural henna coloring strengthens the hair, thickens it and gives it volume. However, after the first application, it may be slightly stiffer. Just a few simple steps are enough to enjoy a smooth and shiny hairstyle.

What will help your hair after henna?

Add a little aloe or vegetable glycerin to the henna mixture.
After rinsing, apply a silicone-free conditioner or a herbal mask.
Use oils from the Sattva Ayurveda line – e.g. Brahmi, Bhringraj, Neem

How to choose the right shade of henna for your hair color?

The final effect after henna depends on the initial hair color. Natural hair dye does not lighten, but emphasizes the natural shade and reacts with it. The lighter the hair, the lighter the effect.
