Before beginning your blonde hair journey, you’ll need to decide which shade of blonde you’re going for. If you want a preview of what different shades of blonde, like ash blonde or honey blonde will look like, check out the L’Oréal Paris Hair Genius Virtual Hair Color Try-On tool which lets you upload a selfie or try on various hair color shades in real time using your phone or computer’s camera.

Getting blonde hair requires bleaching — and the darker your starting shade, the more work may be required to reach your desired shade of blonde hair. If you have super-dark brunette hair and want to go blonde, don’t expect your hair to magically transform into a beautiful blonde color after one sitting. It’s important to remember that you may need a few bleaching and coloring sessions to achieve your dream hue.

For a DIY at-home blonde hair color you can check out some online tutorials to help guide you through the process. And of course, you should always follow the directions on your at-home hair color kit. If you're aiming for a light blonde shade or your starting hair color is deep, you’ll likely have to bleach your hair. Try the L’Oréal Paris Feria Hyper Platinum Advanced Lightening System Bleach, which is ideal for dark brown hair and can lighten your hair up to eight levels. After bleaching, you’ll be ready for your blonde dye.

For Light Brown Hair: If you have light brown hair becoming a blonde will require lifting your color a level or two. This needs to happen in order to lighten your hair so that it’s a more receptive base color for blonde dye. You’ll probably need two sessions to make hair magic happen, but (lucky for you) it shouldn’t take too long for you to go from brown to blonde hair.

If you’re looking for a large range of shades to choose from, check out the L’Oréal Paris Superior Preference Fade-Defying Shine Permanent Hair Color line. If you have stubborn gray hairs that you want to conceal, the L’Oréal Paris Excellence Créme Permanent Triple Protection Hair Color line is for you. And if you’re looking for a shimmering color with lots of dimension, opt for the L’Oréal Paris Féria line.

For Dark Brown Hair: If you have dark brown hair, transitioning to blonde will require some patience, but it’s totally doable. If you’re getting your hair colored at the salon, you’ll definitely need to book a few appointments to transform your strands. And you won’t be able to go one day after the next — you have to give your hair time between bleaching sessions to get a lighter color without stripping it of necessary oils and moisture. The wait time will depend on your hair’s specific needs and condition.

While you wait, treat your hair with protein masks to help strengthen it before your next appointment. Try the L’Oréal Paris Elvive Total Repair 5 Power Restore Multi use treatment, which is formulated with a repairing concentrate that includes proteins to strengthen and fix any damage. It’s also a good idea to use strengthening shampoo and conditioner like the L’Oréal Paris EverPure Sulfate-Free Bond Strengthening Color Care Shampoo and L’Oréal Paris EverPure Sulfate-Free Bond Strengthening Color Care Conditioner which helps to repair weak hair bonds in bleached hair, and also helps to prevent future damage.

How To Care For Your New Blonde Hair Color

Once you’ve achieved your ideal blonde hair color, make sure you give it the extra care it needs to keep it in excellent condition. Swap out your regular hair care arsenal for products that are specifically formulated for color-treated hair.

If you’ve noticed your hair has gotten brassy, you’ll want to add a purple shampoo into your blonde hair care routine. To combat the brass, reach for the L’Oréal Paris EverPure Brass Toning Purple Sulfate Free Shampoo, L’Oréal Paris EverPure Brass Toning Purple Sulfate Free Conditioner, and the L’Oréal Paris EverPure Sulfate-Free Anti Brass Purple Mask Treatment to hydrate your hair and neutralize yellow and orange tones in blonde, bleached hair.
