NXT Demi-Permanent Hair Colour 100ml

NXT Demi-Permanent Hair Colour (100ml) is a mildly oxidising colour solution that delivers rich, lasting results with a soft fade over 18 to 24 washes. More durable than traditional semi-permanent formulas, it provides up to 50% white hair coverage and a 70% blend, making it ideal for clients seeking low-commitment colour with salon-level longevity.

Ammonia- and paraben-free, this formula is gentle enough to use after perming or straightening and works beautifully for toning bleached, lightened or natural hair. Paired with a specialist low-peroxide developer, it adds vibrant tone and shine to virgin lengths while offering a dependable, affordable option for colour correction or refresh services.
