Discover the solutionThe protocol for stimulate growth without irritation
Scalp microcirculation can be stimulated in ways other than triggering an inflammatory reaction. Exfoliation is used to open the hair follicles and relieve congestion, followed by cleansing at pH 5 without damaging the skin barrier. Then, active ingredients are applied whose effect on the follicle is measured, not based on sensation. It's a longer process to explain, but it's what provides lasting results over several months.
