If your Philips Curler allows you to change the temperature settings, select the temperature suitable for your hair type. Thin, fine hair can be curled much easily so do not require a very high temperature. For thick hair, use high temperature settings. For more detailed instructions on how to use the settings of your hair curler please refer to your user manual. If you are still not happy with the performance of your Philips Hair Curler, feel free to contact us for further support.
