Fortifying Hair Treatment
Professional, salon-grade care for weak, fine or thinning-feeling hair — an intensive leave-in lotion that works where stronger hair begins: at the scalp and the roots.
Developed in Insight's own laboratories in partnership with the University of Bologna, the Fortifying Hair Treatment is built on a fortifying phytocomplex of Oorganic Horse Chestnut, Guaraná and Watercress that works at the root to strengthen the hair fibre and support a healthy, balanced scalp. A fresh infusion of peppermint, tea tree and menthol delivers an invigorating, cooling tingle as you massage it in, while the lightweight, non-greasy formula absorbs cleanly without weighing hair down.
Backed by professional testing. In laboratory (in vitro) efficacy testing, the Densifying range was shown to help reduce hair loss — and in a 56-day trial, 95% of users reported stronger hair and scalp, with hair that looked visibly thicker.*
Trusted in the salon. Used and recommended by professional hairdressers for clients with weak, fine or thinning hair — the intensity of an in-salon treatment, designed to deliver results at home.
