Personally, I find it difficult to use practically. You cannot "just" shower because the product has to be absorbed for 20 - 30 minutes. I am still looking for a good method to apply it to my hair. 😅 For me, the powder also sticks on my breath, which is not pleasant.
But it does its job! My curly hair feels fresh and nice and it lasts about a week until it is greasy again.
