What’s Inside (Full Size)

• Gray Hiding Treatment (Full Size) – multi-use bottle for repeated applications.*
• 2 x Booster Serum – target stubborn/darker grays for deeper results.

* Actual number of applications varies by hair length, density, and usage (all-over vs. root touch-ups).

How It Works

Inochroma’s melanin-precursor technology builds colour within the hair fibre, delivering natural-looking gray coverage without harsh chemicals or strong odours. Use repeatedly to blend salt-and-pepper or go for richer, fuller coverage.

How to Use

First, put on gloves.

Then, apply the booster serum evenly to dry hair leave 5 mins.

Next, apply treatment to the area, leave 10-20 mins.

Finally, rinse thoroughly, then shampoo and condition as usual.
