OLAPLEX have launched a new and revolutionary scalp health innovation to create ageless hair, by way of their new No.0.5 Scalp Longevity Treatment. This daily scalp serum has been designed to create the foundations of healthier, softer and shinier hair, transforming scalp care in the process.
The product is anchored by the Proprietary Scalp Barrier-Building Complex, which is built with OLAPLEX’s Patented Bond-Building Technology™ in a multi-functional formula that provides instant hydration and soothing while ensuring long-term scalp barrier repair. An Antioxidant-Rich Blend of Lavender Extract & Tazman Pepper Extract also serves to strengthen and protect the scalp barrier and microbiome.

These ingredients protect against damaging free radicals and visibly accelerated scalp ageing, which is caused by environmental stressors such as UV exposure, poor water quality, chemical treatments, hair products, stress, lack of sleep and an imbalanced diet. This healthier scalp environment promotes soft, shiny, and visibly stronger hair by re-linking disulfide bonds within keratin to strengthen the Stratum Corneum and by reinforcing the scalp barrier. Additionally, a blend of essential fatty acids and ceramides provides nourishing lipid replenishment to hydrate a dry scalp.


“Healthy hair starts with a healthy scalp,” said Amanda Baldwin, OLAPLEX CEO. “With No.0.5 Scalp Longevity Treatment, we’ve created a powerful solution that works at the foundation—strengthening the scalp barrier to support the future of stronger, softer, healthier-looking hair. This game-changing formula is designed to deliver long-lasting results, both today and tomorrow.”
The product is delivered as a silky serum that absorbs quickly without leaving residue. It can be used daily on wet and dry hair.
Studies have seen that, using the product, hair is healthier and softer in four weeks, the scalp is five times more hydrated and there’s a 51 per cent improvement in the scalp barrier in two weeks. 80 per cent of respondents said their hair felt nourished after one use.
