I bought mine from Bealls Outlet, and the lady at the register told me that this is the best brand of shampoo and conditioner to use. I also bought this brand in the conditioner. The lady told me that they run out of this product, once they get shipments. It's very popular. I have heard great reviews about Macadamia, and I am excited to try it out. Right now, my hair is straight, since I have gotten a permanent straightening kit done to my extremely curly hair months ago, and my hair is staying straight! Hopefully, this Macadamia Smoothing Shampoo and Macadamia Smoothing Conditioner will help keep my hair straighter!!
