Abstract:
The use of Castor Oil (Ricini oleum) for its laxative-purgative effect is already well-known. The relevant literature describes the empirical use of castor oil for external use, as regenerating agent for hair. The hair-regeneration effect has been studied on experimental animals (rabbits), using two different formulations of the lotions (35% or 40% Castor oil).
After 1 month of treatment, the results we have obtained for the lotion 35% have been very positive, while the results obtained for the lotion 40% were not satisfactory. For the lotion 35%, in more than 50% of the cases, the hair has grown longer and thicker compared to the blank areas. The weight of the animals increased and the fur became nicer and softer. No adverse reactions or death cases have been reported during the study. Based on the results we have obtained, we can conclude that Castor oil (Ricini oleum) used as lotion for external use 35% has a stimulating and regenerating effect on hair. On the treated areas the hair grows stronger.
