The best way to take care of anything is ‘prevention’. Split ends alert is more so in the hot Summer months when you are putting your hair up often and are in the hot sun. Also, another culprit are the Winter months when you hair is often under harsh indoor heat. Of course, this applies to you 24/7 if you are using a heating tool on your hair for style.
TIP: Take a little of your favorite oil: Argan, Coconut, Olive, Etc.. into your palms and dab on the ends of your hair before exposure to elements or after you apply your styling heat.
