There are two things you need to keep in mind when you use heat styling tools like the curling wand or straightening iron on your hair:
Avoid Heat Styling
While it is best that you stopped using heat styling tools altogether, a good compromise is to limit your heat styling to once or twice a week. After all, applying heat to your hair too often can cause split ends and damage to your hair.
Apply Heat Protectant
Always, always, always apply a heat protectant to your hair before straightening or curling it. This acts as a barrier between your hair and the heat, thus protecting your tresses from untold damage.
Apply conditioner only on the ends: Applying conditioner all over your hair from root to tip can create a lot of build-up on the scalp. Apply conditioner only from the mid-length to the ends of your hair and wash it off after 2 minutes.
Don’t wash your hair every day: The last and most important tip for washing your hair is this – Don’t. Wash. Your. Hair. Every. Day. While you may think you are being very hygienic, all this will do is dehydrate and damage your hair, strip it of its natural oils, and make it more prone to breakage and hair fall.
