I love this pillow case. My kids keep threatening to steal it! Ha! I have not noticed that my hair is less frizzy, but I have really enjoyed the feel of this pillow case (It's so soft!). I was worried that the slickness of the silk would cause my pillow to try to slip away from me in the night, but I honestly haven't had that problem. And I love that it has a zipper and is not just a slip-in pillowcase. I would recommend this pillowcase!
