I have used this product for over a year. I did not notice any noticeable growth. It was soothing to the scalp, but I did not find that it went very far. Having medium-thick curly hair I had to use a fair amount per use as I did not find it spread throughout my hair with ease. I would not recommend, the effectiveness of the product was ‘weak’ in comparison to its marketed ‘value’. I would not recommend it, especially based on the high price.
