Tips for Maintaining Blonde Dyed Hair

Blonde hair can look stunning, but blonde dyed hair requires extra effort to keep it looking its best. If you don’t care for your blonde hair properly, it can become dry and brittle and may turn yellow or brassy.

Due to the bleaching process, blonde hair is more fragile and delicate than other colors. It needs extra protection from heat, harsh products and environmental factors that can cause discoloration and damage to hair. In this post, you can learn about some good methods to minimize damage after dying your hair blonde and some useful tips on how to maintain your blonde color longer. There is also a range of related products you can choose from, to protect your new blonde hair from further damage and prevent your beautiful color from fading and turning brassy.

Blonde Hair Care

Avoid Heat Damage

You should never apply the flat iron without completely drying your hair.  Allow your hair to air dry if possible. Make sure to apply a heat protectant if you are going to use heat. Keep your flat iron below 350 degrees and avoid pressing it tightly. Don’t apply a flat iron before removing all the tangles from your hair.

Shampoo Your Hair Less Often

Don’t wash your hair at least two days prior to bleaching because the bleach will burn your freshly clean scalp.

After the coloring process, wait at least two days before shampooing to allow the color to set properly. Wear a shower cap, so you can shower without wetting your hair. Don’t wash your hair daily because excessive shampooing will remove the protective coating of natural oils and can strip the color pigments.

Switch to sulfate-free shampoos and gently massage the scalp with your fingertips. Follow with a final rinse of cool water, to close the cuticles and help reduce the fading process.

Use Dry Shampoo for Blondes

If your hair starts looking greasy, refresh it using a dry shampoo. Additionally, this product adds volume and leaves your hair soft.

Avoid Excess Sun Exposure

Light colored hair is more sensitive to intense sun exposure than dark hair because it lacks protective dark pigments. Additionally, the chemicals used in the coloring process raise the cuticle and leave the hair susceptible to UV damage and color fading

When you are out in the sun for longer periods, cover your head with a scarf or hat to guard the hair against harmful ultraviolet rays. If you plan to be out under the sun without covering your head, use a spray with UV protection and reapply it regularly.


Conditioning rinses are a necessary part of the hair care regimen for blonde dyed hair. Conditioners infuse your hair with moisture and close the cuticle, which helps color stay inside the hair.

Deep Conditioning

Since colored hair needs lots of moisture and protection, use a deep conditioning treatment once a week. Deep-acting conditioners moisturize the scalp and hair, help repair damage and prevent breakage. This treatment will also restore shine and keep your color looking fresh and beautiful.

Hair Oil for Blondes

To restore moisture and shine to damaged hair, apply Moroccanoil Light Oil to the ends of your hair. This oil will help with styling and protect your ends from dryness. This lighter version of Moroccanoil oil is developed to avoid any discoloration that applying hair oils can leave on lighter blonde shades. To avoid frequent washing, you shouldn’t apply the oil near your scalp.

Purple Shampoo for Blonde Hair

Over time, blonde dyed hair can take on an unattractive yellow and orange color. Purple/blonde shampoos are designed to brighten blonde and silver hair and to tone the brassy color. These shampoos work by depositing violet pigment to neutralize yellow tones.  Look for a plant-based blonde shampoo that has a dark purple color.

Use blonde shampoo once per week and leave it on your hair for the recommended time.  Using a purple shampoo too often or leaving it on longer than directed can leave purple hues. Meanwhile, use a sulfate free and/or color safe shampoo.

Shampoo for Swimmers

If you’re going to swim, protect the hair using a protective leave-in conditioner before entering the pool. Follow any pool time with a shampoo for swimmers to prevent chemical build-up and any discoloration caused by chlorine.

If you live in an area with hard water, use products that will counteract the effect of mineral deposits on your hair or invest in a shower filter to prevent the hard water minerals from reaching your hair. 

Hair Lightening Shampoo

This shampoo progressively lightens your blonde hair by reducing the color pigments. A lightening shampoo is free of ammonia and peroxide and utilizes natural ingredients like chamomile, citrus extracts, and honey to gradually lighten your locks. This product also cools down the brassy and yellow tones.

Hair Lightening Spray

A lightening spray is designed to lighten highlighted, bleached, color-treated and naturally blond hair as well as light-brown hair. The formula uses citrus, chamomile, and honey, and works with styling heat to gradually lighten hair. Certain formulas include bleaching agents, while others use only natural, plant-based lightening ingredients. The results are visible after 3-5 uses.

Leave in Conditioner for Blondes

Leave in conditioners for blondes are specially formulated to help reverse damage from bleaching and cancel out brassy tones. Apply the treatment to your towel dried hair and just leave it in. It helps with combing and gives your hair moisture, manageability, and shine.

Hair Glaze Treatment

Get hair gloss or hair glaze treatment two weeks after your hair is colored. This treatment will refresh the color, fix any brassiness and boost shine. You can apply an at-home glaze treatment every 2-4 weeks to maintain a bright color and shine.

Regular Trims

Routine trims are necessary to remove split ends. Trimming on a regular basis (every four to six weeks) will prevent the ends from splitting and helps maintain healthy-looking hair.

Root Touch- Up

Around one month after coloring the noticeable color step between new grown and colored hair starts to surface. Although hiding your roots is not necessary, you still have some options to easily get rid of the dark roots.

Color touch up kits are particularly suitable for touching up your roots at home. These permanent color kits come in shades designed to match different colors. The product is easy to use and takes only ten minutes to apply.

Another way to extend the time between regular coloring sessions is using temporary root concealers, which will hide your roots until the next shampoo.

Hair Toner 

Hair toner is used to neutralize yellow and orange tones and to create delicate shades on pre-lightened hair. The toners usually need to be mixed with either a 10 or 20 volume developer. Paul Mitchell Flash Finish Toner needs to be mixed with 5 volume developer, which is a gentler option to achieve the desired tone of your blonde hair. Higher strength developers contain more hydrogen peroxide which can cause damage to hair.


It is highly recommended to consult a well-trained colorist to help you achieve and maintain your desired level of blonde, with minimal damage to your hair. When re-applying the color to bleached hair, it is important to only lighten your roots without overlapping on previously lightened hair.

To minimize damaging effects of lightening your hair, find a salon that carries Olaplex.  This product enables colorists to lift your color to a lighter level, without significant damage to hair. It repairs the structure of previously damaged hair from the inside and helps reduce breakage after color service. There are also several Olaplex alternatives available, so consult your stylist which color additive to include in your color service.

Use The Neutral Protein Filler as a pre-color treatment to normalize hair porosity for better color results and to protect hair against new chemical damage.

Include keratin enriched hair care products in your hair care regimen. Shampoos, conditioners, or leave in conditioners that contain hydrolyzed wheat protein, hydrolyzed silk, or hydrolyzed keratin will replenish your hair with missing keratin, making it stronger, less porous and shinner.
