If you’re bleaching your hair, don’t forget heat protection! After all, it’s not just about getting that head-turning colour — you want to keep it looking beautiful for years. Blonde hair can look gorgeous and head-turning. However, damaged blonde hair can also look awful and might turn heads for the wrong reasons. Fortunately, we have many ways to protect your bleach-blonde locks from heat damage. Read on for our guide to heat protection for bleach-blonde hair.

Heat Protection For Bleach-Blonde Hair

Heat styling tools like hairdryers and straighteners can wreak havoc on your delicate bleached hair if misused. But with the right products, you can keep your newly blonde hair looking awesome without frying it. Here’s what you need to know about heat protection for bleach-blonde hair:

Start with the right products: Look for a heat protectant spray or serum designed explicitly for bleached hair. These formulas have unique ingredients that help to lock in moisture and provide extra protection from the heat of styling tools. We’ll cover this soon!

Don’t go too hot: You don’t need to crank up your styling tools to their highest temperature setting — lower, medium-level settings will do the trick just fine and cause less damage. Some hair tools like ghd are automatically set to the optimum temperature, so that’s a bonus.

Don’t style too often: While it is tempting to style your hair every day, try to leave a day or two in between styling sessions. This will give your hair time to recover and strengthen its natural protective barrier before being exposed to

Make sure your tools are clean: Before using any heat-styling tool on your hair, make sure it’s clean and free of dirt, product buildup, and other debris. Dirty tools can cause additional damage to delicate bleached hair.

Why Is Bleach-Blonde Hair Prone To Heat Styling Damage?

Healthy Hair With Heat Protection For Bleached-Blonde Hair

Bleach is a powerful chemical that can strip your hair of natural oils, leaving it dry and brittle. This makes it more prone to damage from heat-styling tools. When heat tools come into contact with your hair, they can cause increased breakage and split ends, making it even more fragile.

That’s why using the right products and taking extra care when styling is essential for keeping bleach-blonde hair looking beautiful and healthy. This can be counteracted by in-salon treatments such as Olaplex and the appropriate home hair care routine.

Easier & Cheaper To Prevent Heat Damage

Use Heat Protection For Bleached-Blonde Hair When Styling

Looking after your hair from the start is always more straightforward — and cheaper! — than having to repair it afterwards. Investing in good quality hair care products such as shampoo, conditioner, and heat protectors is essential. Choosing the right tools and temperature when heat styling can make a huge difference.

Signs That Your Hair Is Heat Damaged

Check If Your Hair Is Damaged

Damage is often hard to spot, as it doesn’t always show up as split ends or breakage. Some of the signs that your hair is damaged by heat are dull and dry-looking hair, excessive frizziness, and a lack of shine. You can even do a stretch test on your hair.

To do the stretch test, first, take one strand of hair, spray it with water or run it under the tap. Next, you want to grab each end between your fingers and gently stretch it a little. It can be damaged if your hair doesn’t shrink back into shape, breaks or coils up. Your hair is in good condition if it can be stretched out and retracts easily.

If you notice any of these symptoms in your bleach-blonde locks, it’s time to take extra precautions with heat styling tools and invest in good quality heat protection products.

What To Do If Your Hair Is Severly Damaged

If your hair is severely damaged, DO NOT use heat-styling tools like straighteners or tongs! You’ll first need to go about improving the condition of your hair, which can be done by having in-salon treatments, regular trims and maintaining a good home care routine. You can also use at-home repair treatments and masks to get your hair back in good condition. Once your hair is back in a better state, you can start using heat styling tools again — but this time with heat protection.
