Dione UK Complete Keratin Ritual — Shampoo, Conditioner, Hair Mask & Serum for Dry, Damaged & Chemically Treated Hair

Both bottles are built on the same hero. Hair is mostly keratin; colour, heat and chemical treatments strip it out. The shampoo cleans without taking more of it away, and the conditioner puts it back where the damage is worst.

Keratin: The protein hair is built from. Smooths the cuticle, cuts frizz, rebuilds strength and restores shine.

Sulfate-Free Base: Cleanses and conditions without harsh detergents, so colour and moisture stay put.

Every wash

1.  Shampoo — Wet hair with lukewarm water. Work a coin-sized amount into scalp and lengths for 2–3 minutes, then rinse until the water runs clear.

2.  Condition — Apply to mid-lengths and ends of damp hair, skip the roots. Leave 2–3 minutes, then rinse cool.

3.  Serum — On damp or dry hair, warm a few drops between your palms and smooth from mid-lengths to ends. Comb through, then style.

Once a week — the mask replaces your conditioner

4.  Mask — After shampooing, towel-dry and work the mask through, focusing on the ends. Wrap in a towel, leave 5–10 minutes, rinse. Finish with the serum as usual.
