I find John Frieda product line to be reliable for producing somewhat positive results for my healthy, thick, curly but frizzy hair. In the past, I've used JF Brilliant Brunette Shine Release Moisturizing Conditioner to tame my frizzies yielding a soft sheen to my hair. However, the results were temporary. By nightfall, it was back to the drawing board. I must admit, my hair is extremely frizzy. I do believe what works for some, may not work for everyone. I recommend giving it a try.
