    A must have!

    I love this product! Initially, I thought it was only for younger women, but after a recommendation from one of my students, I became a loyal customer. I feel out of place when my hair doesn’t smell like Rizos. The scent is amazing, and the product truly works if you're starting to lose your hair. I also appreciate supporting businesses owned by fellow Latinas.
