Good things don't come easy. This hair straightener not only has temperature metre it also gives your hair a healthy shine. I use it once when I wash my hair and it stays straight and healthy until I wash. Few things to keep in mind while using it. Wash it, yes you read it right. Wash the plate of your straightener often to avoid breakage in your beautiful hair. Do not use in unwashed hair. Use heat protection spray before using it. Always remember to keep the temperature of heat medium to low. It will help you maintain beautiful straight hair and to avoid split ends. This hair straightener is a good investment for two good reasons- it is not time consuming, it has long lasting results. Keep your hair open all day long without any fear of breakage and split ends.
