1. Prepare the paste: mix the powder with lukewarm water at about 35–40°C until you obtain a yogurt-like consistency, creamy and smooth.
2. Wash your hair first apply to clean, freshly washed hair, without conditioner or masks. Dry or damp, it doesn't make a difference.
3. Apply carefully: distribute the paste throughout the hair, from roots to ends, ensuring even coverage.
4. Cover and heat: wrap the hair with a shower cap or plastic wrap. Use a heat source — hair dryer at regular intervals or a heat cap — to promote color penetration. Leave on for the indicated time.
5. Rinse thoroughly: remove all the paste with plenty of water. Use a conditioner or mask during rinsing to facilitate removal.

Respect the times: wait at least 48 hours before washing your hair with shampoo, to allow the color to set as best as possible.The amount of powder depends on the length and mass of the hair. Approximately:

The Eril Hazelnut Brown Color Ritual Kit brings together three complementary products to care for your hair from plant-based color to styling: Jasper, Multi-Action Hair Mask and Color-Fixing Volumizing Spray.

Jasper provides a warm medium brown with hazel highlights; the mask softens and tames the lengths; the spray helps improve color retention while adding body and volume. A routine designed to enhance the results of herbal color and keep your hair soft, shiny, and manageable even in the days following the treatment.

What the kit contains

• Jasper — 2 x 100 g packages, for a total of 200 g
  100% plant-based, vegan, and organic color mix. Tested for heavy metals and microbiologically, it provides high gray coverage. The processing time is 60–120 minutes.
• Multi-Action Hair Mask — 200 ml
  Multifunctional mask that nourishes and softens, improves combability, and helps tame the lengths. The formula contains functional ingredients such as organic baobab oil, fermented rice water, organic aloe vera, and a green walnut phytocomplex. You can use it as a rinse-out mask, a quick conditioner, or, in small quantities, as a leave-in styling product to shape and define your hair.
• Color-Fixing Volumizing Spray — 100 ml
  Lightweight leave-in spray designed to help improve the retention of plant-based color and limit pigment fading. With pomegranate liposomes, rice proteins, and a green walnut phytocomplex, it adds body and volume and supports your style. Use on towel-dried hair after the color treatment or on dry hair to refresh your style.

The two packages of Jasper provide extra powder for application to long or thick hair. If you use less, you can keep the unopened package for a future color application or touch-up.

How to use the kit

1. Color with Jasper. Mix the powder with warm water at approximately 35–40 °C. Apply to freshly washed hair without conditioner or mask. Cover with a cap, keep warm, and leave on for 60–120 minutes. Rinse thoroughly.
2. Add softness with the mask. Distribute the Multi-Action Hair Mask through the lengths, leave on for a few minutes, and rinse. Alternatively, use a small amount on damp hair as a leave-in without rinsing.
3. Finish with the spray. Spray the Color-Fixing Volumizing Spray onto towel-dried hair, focusing on the roots and, if necessary, the lengths as well. Distribute gently and blow-dry without rinsing.

Wait at least 48 hours before your next shampoo. For subsequent washes, you can continue to use the mask according to your hair's needs and apply the spray to dry hair in small amounts for added support and volume.

What results to expect

Jasper does not lighten. The final shade and coverage depend on your starting base, porosity, and hair structure.

Perform a sensitivity test before use and always follow the instructions and warnings on the individual product packages.
