Why split ends happen.

Split ends happen due to a number of causes, but basically, they happen when the hair’s outer layer (the cuticle) starts to break down. This can lead to dryness, hair breakage, and, you guessed it, split ends- and finally, irreversible, hair damage.

Dehydration

A lack of hydration or moisture is a key factor in the appearance of split ends. Dry hair tends to be more fragile and prone to splitting.

Heat exposure

Exposure to heat, generally through heat styling (with blow dryers, curling irons or hair straighteners) can also weaken the hair, leading to dryness, breakage and split, frayed ends.

Daily haircare routine

Now that you know why and how split ends happen, what can you do? To get rid of split ends, you’ll have to get them trimmed, but to prevent split ends and repair damage, here are a few tips for a healthy, hydrating daily haircare routine.

Gentle cleansing

The basics of a healthy haircare routine? Wash hair with a gentle or repairing shampoo that cleanses without stripping away moisture.

Strengthening ingredients

When it comes to treating or preventing split ends, there are some key ingredients to look out for, actives like amino acids, which can be helpful strengthening ingredients that prevent breakage and ultimately, split ends.

Amino acids

Amino acids are proteins that can help strengthen the hair fiber and protect the hair from future damage. This can help reduce new split ends from forming.
The L’Oréal Professionnel Pro Longer Mask for example, is specifically formulated with an exclusive combination of FILLER-A100 and Amino Acids to renew lengths and fill-in ends.
