For me, this worked for my hair. After two months of use, my hair has grown twice as fast as usual with two washes per week on average. I know for some people this is not the case. The only problem is that the product dries hair. I add a nourishing mask and a leave-in to avoid this inconvenience. I also do a wash before castor oil bath once every two weeks. Although a cure for three months once or twice a year.
