Crescina R 5 Complete Re-Growth & anti-hair loss care 500 is for men with advanced serious thinning & hair loss Crescina R5 is a Swiss patent formula for supporting natural hair growth. Crescina R5 preparations act on hair bulbs that are not completely inactive, in areas of the scalp that are thinning. As the situation progresses, the stage of thinning becomes progressively more significant. Crescina preparations therefore use various formulae, designed for different degrees of thinning. The efficacy of Crescina has been proven by numerous tests on volunteers conducted at hospitals & research institutes in different countries. Findings from the tests show rates of growth up to 45% on individuals. Unlike generic hair loss products, Crescina R5 acts on hair bulbs that are not totally inactive, employing a patented, specific mechanism to help them to produce the keratin needed for new hair growth.
