Having already transformed our skin care regimes, we could only dream that The (extraordinary…) Ordinary would branch out into hair care – and, with this Multi-Peptide Serum for Hair Density, they have! According to the brand itself, this concentrated formula ‘is designed to support hair health so that it looks thicker, denser, fuller and healthier’ – all words we’d very much like to use to describe our own (occasionally lacklustre) locks. So, how does it reap these miraculous results? A combination of potent natural extracts (Larix Europaea Wood Extract and Camellia Sinensis Leaf Extract), peptide complexes and caffeine power this ultra-lightweight formulation, united in an emollient base so that it can effectively penetrate your scalp and work deep within hair follicles. Ideally, use it at bedtime, applying it to a clean, dry scalp before massaging in thoroughly and leaving it on (some may prefer to rinse in the morning).
