Suitable for men and women.

Key actives and what they do

• Henna Extract — A natural plant-derived colourant derived from Lawsonia inermis. Deposits rich, warm colour onto the hair shaft while conditioning the cuticle. Henna has been used for centuries as a hair colourant — in this shampoo format, it delivers gradual, buildable colour with each wash rather than a single permanent application. Provides 100% grey coverage with consistent use.
• Keratin — A structural protein that is the primary building block of hair. Keratin in the formula fills gaps and damage in the hair cuticle, smoothing the surface and reducing frizz. Hair feels stronger, smoother, and more manageable after use. Particularly beneficial for hair that has been weakened by heat styling, chemical treatments, or environmental stress.
• Olive Oil — A rich emollient that penetrates the hair shaft to deeply nourish and hydrate. Reduces dryness and brittleness, adds shine, and improves the overall condition of the hair. Particularly effective for dry, coarse, or chemically treated hair — common in the UAE’s dry climate.
• Vitamin E (Tocopherol) — An antioxidant that protects the hair and scalp from oxidative stress caused by UV exposure and environmental pollution. Supports scalp health and helps maintain the vibrancy of the colour between washes.

What to expect

Immediate: hair feels clean, soft, and conditioned after the first use. A subtle colour deposit is visible from the first wash. With consistent use over 3–4 washes: progressive grey coverage builds to full coverage, colour appears richer and more even. Colour intensity can be adjusted by varying the leave-on time (3 minutes for lighter coverage, 5 minutes for deeper coverage). No staining of skin or surfaces when used as directed. rinse thoroughly after each use.

Who it is for

• Men and women with grey hair wanting easy, at-home colour without the commitment of permanent dye
• Anyone wanting to colour and condition hair in a single step
• Anyone with a sensitive scalp who reacts to ammonia-based hair dyes
• Anyone in the UAE climate where UV exposure and dry air accelerate hair colour fading and dryness

Who it is not for

• Anyone wanting to lighten hair — this shampoo deposits colour and cannot lighten existing hair colour
• Anyone with a known allergy to henna or plant-based colourants — perform a patch test 48 hours before first use
