A clinical test which established that Crescina is an adjuvant in natural hair growth and is also a preparation that will help cut down scalp hair thinning. The tests were undertaken by the medical team of the Dermatology Clinic at a public hospital in July 1999.
The research took 6 months and there were thirty volunteers, 19 of whom were male and 11 were female, between 20 and 52 years of age. The males were affected by thinning up to level V on the Hamilton scale, and the females up to level III on the Ludwig scale. The right-hand side of the scalp was treated with Crescina lotion, whilst the left-hand side was treated with a placebo lotion.
