What Causes Split Ends and How to Prevent Them

What Causes Split Ends and How to Get Rid of Them for Good

Let’s face it, split ends are awful. Frizzy, dry-looking messes that make even healthy hair look unkempt at the tips. Research shows over 60% of women suffer damage from split ends caused by heat exposure alone (and that’s not even including other damage factors), which speaks volumes about how stressful daily styling routines can be to the hair shaft over time. You cut them off only for them to reappear seemingly weeks later. How can you get rid of them? And what are the best split ends hair treatments?

What Causes Split Ends? 

Split ends occur when the hair’s cuticle layer wears away. When the cuticle is gone, there’s nothing protecting the inner fibres, which causes them to split apart. While there are many sources that can cause split ends, here are the main ones to look out for.

Heat Styling 

Heat tools like hairdryers, straighteners, and curling wands are damaging to hair. Continued use can weaken your hair shafts, causing them to break off or split at the ends. Heat raises the cuticle by breaking down hydrogen bonds and damaging the hair’s protein structure. Once they’re gone, hair loses its elasticity, causing it to snap rather than bend. If you style your hair with heat daily, you will most likely continuously have split ends no matter how well you care for the rest of your hair.

Overwashing & Harsh Shampoos 

Daily shampooing, especially with sulfate-based formulas, strips hair of moisture, leaving it dry and brittle. Brittle hair is far more likely to have split and broken ends. The more you wash your hair, the drier it gets. By switching to a sulfate-free shampoo like GK Hair Moisturizing Shampoo and Conditioner, you can break that cycle before it begins. It’s a great shampoo for split ends.

Rough Towel Drying 

Rubbing your hair vigorously with a towel might seem like a helpful way to speed up the drying process but all that rubbing creates friction that roughens up your cuticle and weakens your hair shafts’ outer layer. Once that cuticle is gone, there’s nothing to protect those inner fibres, causing split ends to occur. Try squeezing your hair rather than rubbing and allow your towel to absorb excess moisture rather than dragging it through your hair.

Chemical Processes 

Chemical treatments, including bleaching, colouring, etc., damage your hair’s protein structure, causing it to become weaker and eventually split. Basically every chemical process you put your hair through lifts the cuticle to either deposit colour or strip it away. This weakening accumulates over time, so the more frequently you undergo chemical treatments, the more damage you’re doing to your hair. Always allow at least a month in between colouring or lightening to give your hair time to recover.

Not Enough Moisture 

Dry hair is very prone to having split ends. When your hair lacks moisture, it loses its flexibility, meaning it cannot bend without breaking. Breaking is essentially what split ends are. One of the worst parts about dry hair is that the lack of moisture can go unnoticed until you start to see damage at the ends of your hair.

Brushing Your Hair When Wet 

When hair is wet, it is in its weakest state. Water swells the hair shaft and raising the cuticle. Basically, everything about wet hair makes it easier to stretch out and snap. By brushing or combing your hair too harshly when wet, you’re putting tension on your hair that it can’t handle, causing breakage and eventually split ends. Always use a wide-tooth comb on wet hair.

Pro Styling Tip: Use a t-shirt to dry hair. Microfiber towels and old cotton t-shirts are much gentler on hair than towel sheets.

How to Prevent Split Ends 

Now that you know what causes split ends, here’s how to get rid of split ends. 

  • Apply a heat protectant: If you can’t live without your straightener, make sure you’re always using a heat protectant like GK Hair ThermalStyleHer Cream. Heat protectants create a barrier between your hair and reducing heat related damage.
  • Trim hair regularly: Trimming your hair every 6–8 weeks is the best form of split ends prevention there is. By cutting off those split ends you’re stopping damage from traveling up the hair shaft. Quick fix? Have regular trims scheduled at your salon of choice.
  • Use a sulfate-free shampoo: Want to prevent your hair from becoming dried out and prone to splitting? Use a gentle sulfate-free shampoo and conditioner like GK Hair Moisturizing Shampoo and Conditioner. Sulfates are extremely drying, which is why using shampoo and conditioner formulated without them is so important.
  • Handle hair with care when wet: Avoid brushing or rubbing your hair when wet. Wrap your hair in a t-shirt or microfiber towel to dry and use a wide tooth comb to detangle.
  • Use a hair mask for split ends: Weekly deep conditioning is different from your regular shampoo and conditioner. A hair mask for split ends is specifically designed to penetrate the cuticle and restore moisture and protein lost from heat styling, washing, and environmental exposure. Our Deep Conditioner Hair Treatment works by penetrating the hair shaft and rebuilding weakened areas from within rather than simply coating them like regular conditioners.
  • Protect hair overnight: Cotton pillowcases are bad for your hair. They might not seem like it but friction against cotton all night is enough to cause breakage. Investing in either a silk or satin pillowcase is a simple change that can make a big difference.
  • Reduce use of chemical treatments: If you colour or bleach your hair frequently, try cutting down and spacing your sessions. GK Hair also has Shield Additive+ which can be mixed into your colour to help minimise damage.
  • Seal your ends: A good hair serum for split ends will smooth down the cuticle and lock in moisture between washes. Two ingredients to look for are keratin and argan oil. Keratin helps fill in weakened areas of the hair shaft, while argan oil helps seal in moisture without weighing hair down. GK Hair Argan Oil Serum does both and it’s light enough to use daily.

Frequently Asked Questions

What’s the best split ends hair treatment I can do at home?

Truthfully, a combination of weekly hair mask for split ends and daily serum is your best bet. GK Hair Deep Conditioner will help with rebuilding your hair from the inside, while GK Hair Argan Oil Serum is perfect for exterior protection. It is the best hair serum for split ends. Using one without the other isn’t nearly as effective as you’ll see by sticking to a routine with both.

How often should I use a hair mask for split ends?

Once a week is perfect. If your hair is extremely dry or has been chemically treated, using a hair mask twice a week is okay, but any more than that could cause limp hair.

Can hair serum fix split ends? 

Hair serum can’t reverse split ends that have already formed. It can, however, smooth down those split ends temporarily and help prevent further splitting by sealing in moisture.

What causes split ends to keep happening to me?

Nine times out of ten, something is still happening in your routine that’s continuing to cause damage. Maybe you’re blow drying without a protectant, using shampoo with sulphates or rough drying your hair when it’s wet. Trimming your hair gets rid of those pesky split ends but it won’t prevent new ones from forming if you aren’t tackling the root of the problem.
