Quercetin
Quercetin (derived from a American oak tree) is a very highly concentrated form of bioflavonoids derived from citrus fruit. Its active ingredient, isoquercitin, is used in dark brown hair-dye shades but employed mainly for dyeing artificial hairpieces.
Testimonial
“Would like to see more companies get involved with BeauteSchool! We really need training and most of our companies will not send us to courses anymore due to the costs. We need to learn to grow. I am constantly trying to stay on top of new products and this really helped. Thank you so much! I will definitely be back for more.”
