TONING + STRENGTHENING

The Amethyst Duo is a precision-led haircare set created to support coloured, treated, or heat-damaged hair that requires strength, control, and tone retention.

This set includes an Amethyst crystal and Crystal Earth comb to support mindful application without detracting from performance.

Mineral Fusion Technology · Amethyst

Amethyst is traditionally associated with clarity and refinement.

Within Crystal Earth, Amethyst is used to crystal-code both formulations, offering subtle energetic qualities while maintaining a clear focus on performance, structure, and longevity of results.

This duo is designed for consistency, control, and visible improvement over time.

Key Formulation Highlights

  • Vegetable Protein helps penetrate the hair fibre, supporting internal strength and reducing breakage

  • 93% naturally derived

  • Vegan and cruelty-free

  • Free from parabens, sulphates, and silicones

The Ritual

Cleanse with Amethyst Shampoo, focusing on the lengths and areas most affected by colour or damage. Rinse thoroughly.

Apply Amethyst Conditioner through mid-lengths and ends only.
Leave briefly, then rinse.

Use the ritual comb to distribute product evenly and minimise breakage during detangling.

Fragrance

A fresh yet refined fragrance with green and woody depth.

Green, fruity top notes of fig and fig leaf open into a soft floral heart of rose and jasmine, settling into a woody base of cedar and sandalwood, warmed with amber.

Conscious Care

Packaged in recyclable and refillable bottles, designed to support a more circular approach to beauty.

TOP QUESTIONS

Is Amethyst suitable for coloured or treated hair?

Yes. The Amethyst range is specifically designed for coloured, lightened, or chemically treated hair.

The formulations focus on maintaining tone, supporting strength, and reducing breakage, helping coloured hair look healthier and more resilient over time.

Will Amethyst help strengthen damaged hair?

Yes. Our Amethyst products contain vegetable protein that helps penetrate the hair fibre, supporting internal strength and improving resistance to breakage.

With regular use, hair feels stronger, smoother, and more controlled, particularly through the lengths.

Can I use Amethyst if my hair is fragile or prone to breakage?

Amethyst is well suited to hair that feels weakened, fragile or over-processed.

The shampoo and conditioner are designed to cleanse and condition without stripping, while reinforcing the hair structure to support durability and manageability.

Should Amethyst be applied to the scalp?

Amethyst is designed primarily for use through the lengths and ends of the hair.

To achieve the best results, focus application on areas most affected by colour or heat damage rather than massaging directly into the scalp.

What makes Amethyst different from the other Crystal Earth ranges?

Amethyst is the most results-driven range within Crystal Earth.

While Rose Quartz focuses on balance and Amber on calming the scalp, Amethyst is formulated for precision, strength, and tone retention, making it ideal for coloured and treated hair that requires performance-led care.
