A clinical-grade, stem-cell-derived 6-week topical programme formulated to support healthier hair follicle activity and a calmer scalp. Why it works The CALECIM Hair System is built around PTT-6, a patented compound derived from cord-lining stem cell conditioned media. It delivers a precise blend of growth factors, signalling proteins and exosomes directly to the scalp. Evidence suggests these bioactives may support follicle signalling, encouraging follicles into a more active growth phase while helping to moderate the inflammatory environment commonly associated with shedding and thinning. The result is a considered, biologically informed approach to scalp care, rather than a single-ingredient solution. Clinical evidence Clinical and laboratory studies commissioned by Calecim report: A 24% increase in hair follicle cell growth in laboratory testing, with results comparable to Minoxidil benchmarks. A 30-fold reduction in inflammatory markers around hair follicles, an environment associated with healthier follicle function. In a 12-week clinical study: a 14% increase in hair count, a 16% increase in hair thickness and a 15% increase in follicle density. These figures reflect study findings and are not a guarantee of individual outcomes. Who it's for This system is considered for adults experiencing mild-to-moderate hair thinning, reduced density or a generally unsettled scalp, who would like an advanced, non-pharmaceutical topical option. It is particularly well suited to those seeking an evidence-led, biotechnology-based approach and is frequently chosen by clients continuing their care at home alongside, or following, in-clinic scalp microneedling at LumiLabs. How to use Follow the enclosed 6-week programme. The Hair System is a topical, at-home treatment applied directly to the scalp in the affected areas. Use consistently through the full programme for the most meaningful read on how your scalp and hair respond. Part of a bigger picture CALECIM is at its most effective when paired with in-clinic Scalp Microneedling, which creates controlled micro-channels to support deeper absorption of the PTT-6 compound. If you are unsure whether the at-home system, the clinic-led route or a combined plan is right for you, a consultation with Reena is the natural next step to map out a considered, personalised approach.
