How to prevent split ends
Trim your hair once every 1-2 months, shortening it to 3.5 cm. Yes, this is a lot, especially for those who care about hair length, but preferring length over quality is fraught with even more damage.
Reduce your exposure to heat styling appliances.
Irons, tongs and blow dryers heat hair up to 200 degrees Celsius, drying it out. If you're used to styling your hair regularly, don't forget to use heat protectors!
Brush your hair before you go in the shower: this will reduce the risk of tangles and breakage when your hair is wet. Apply shampoo to the top of your head and gently rinse down, keeping your hair mostly straight and making zigzagging motions with your fingers all the way through.
Try not to brush your hair while it's wet.
This can be difficult, especially if you are in a hurry. But once the action becomes a habit, your hair will feel much happier.
Moisturize your hair - it needs an extra dose of moisture after high heat and active styling. Use a mask at least once a week and try express moisturizers in the form of mists.
Use two types of conditioner.
One that can be rinsed right after shampooing in the shower (it will seal the hair's scales, prevent moisture loss and make combing easier) and one that can be left in place while drying and styling (it will keep every hair healthy for the day by nourishing, moisturizing and protecting it).
