What are split ends?
Split ends are what happens when the hair’s outer layer (the cuticle) starts to break down or wear out due to chemical processing or mechanical stress, like aggressive brushing. With split ends you tend to have more hair damage and hair breakage.
How split ends form
Fiber aging is more visible at the ends than at the roots, as these have been subjected to more aggressions day after day throughout the hair's life. They are often more sensitized and thinner with less body that can lead to split ends and breakage.
Due to the compromised outer layer, the hair’s inner fibers can fray and split, leading to this structural breakdown we know as split ends.

Signs of split ends
Some key signs that you have split ends include: frayed, feathered tips; rough texture at the ends; breakage at tips and mid-lengths; loss of shine; and uneven texture that is easily snags.

What causes split ends?
There are quite a few possible causes for split ends, and we’ll review the most common ones here.
Heat damage
Excessive heat styling (whether with blow dryers, curling irons or straighteners) can weaken the hair and lead to dryness and breakage.
Chemical treatments
Coloring, dyeing, bleaching – these treatments can change the structure of the hair, making it more prone to splitting.
Mechanical stress
Overbrushing or mis-brushing (like using the wrong brush or brushing wet hair), or even rough towel drying, can cause physical damage, causing the hairs to split.
Lack of moisture
A lack of hydration can also cause split ends: dry hair is more prone to splitting.
Can split ends be repaired?
Wondering how to repair your split ends? Well, the only true solution is trimming off the split ends. That said, once you trim the ends, you can practice proper care to prevent split ends from returning.
What trimming really does
Trimming your ends gets rid of the visible problem…at least in the short term. But trimming does not prevent split ends from reappearing. You’ll need to consider tweaks to your haircare routine, from more gentle brushing and using the right treatments, whether that’s to protect your hair from heat styling or to seal ends.
Can products seal ends?
Certain treatments can seal split ends, but getting regular trims is really the only way to remove damaged ends. Products formulated for fiber filler replump and bond repair can function to defend against split ends.
How to prevent split ends
