Maintaining Blond Hair

Blond hair, particularly when it has been lightened through colouring, generally needs more active maintenance than most other hair colours. This page covers the general principles behind keeping a blond shade looking even and the hair itself in reasonable condition.

Managing brassiness

Brassiness refers to the yellow, orange or warm cast that develops in blond hair as the cooler toning pigment fades. It happens because underlying warm pigment in the hair becomes more visible over time, whether due to washing, sun exposure or simply the natural fading of colour.

The most common way to manage brassiness between salon visits is with purple or blue toned shampoos and conditioners. These products deposit a small amount of pigment that counteracts yellow or orange tones, based on the principle of colour theory where purple neutralises yellow. They are generally used less frequently than regular shampoo, since overuse can leave hair looking too cool or slightly grey.

Washing routine

Lightened hair is more porous than untreated hair, which means it can lose moisture and colour more quickly during washing. Many people with blond hair choose to wash less frequently than they might with a different colour, and to use lukewarm rather than hot water, since heat can open the hair cuticle further and accelerate colour loss.

Sun and heat exposure

In a climate with strong, consistent sun exposure, protecting blond hair from UV damage is a significant part of ongoing maintenance. Sun exposure can dry out the hair shaft, weaken its structure, and fade colour unevenly, particularly on the parts of the hair most exposed to direct light. Wearing a hat, using a leave in product with UV protection, or simply limiting time in direct sun are common general strategies. Heat styling tools such as straighteners and curling irons have a similar drying effect and are often used at lower temperatures or with a heat protectant on lightened hair.

Swimming and water exposure

Chlorinated pool water and, in some cases, hard tap water can both affect blond hair. Chlorine is often associated with hair feeling drier and, in very light or previously bleached hair, can contribute to a greenish tint from mineral deposits. Rinsing hair with clean water before swimming, so the hair shaft absorbs less chlorinated water, and washing thoroughly afterwards are commonly recommended general precautions.

Deep conditioning and repair

Because lightening opens and roughens the hair cuticle, regular deep conditioning or protein treatments are often part of a blond hair care routine. These treatments aim to replace lost moisture and strengthen the hair shaft, helping to reduce breakage and keep the hair looking smooth rather than straw like.

Salon maintenance schedule

How often blond hair needs salon attention depends on the chosen shade, the person's natural hair colour, and how quickly regrowth becomes noticeable. Lighter and more dramatic shades, such as platinum, generally need more frequent root touch ups than subtler shades like honey or dark golden blond. Toning appointments, which refresh the colour without further lightening, are often scheduled between full colour appointments to keep the shade looking fresh.

General signs hair needs attention

Increased dryness, roughness or tangling compared to usual
Visible yellow or orange tones appearing between colour appointments
Breakage or split ends becoming more noticeable
Colour looking patchy or uneven rather than consistent from root to tip

Recognising these signs early generally makes it easier to address them with a simple change in routine or product, rather than requiring more significant correction later.
