Blonde hair: how do I take care of it on a daily basis?

While it attracts light like no other, blonde hair is also more fragile. UV rays, pollution and the heat of styling tools are all factors that dull its shine and encourage unwanted tones to appear. Maintaining beautiful blonde color therefore takes special care. Discover how to take care of your hair on a daily basis to neutralize yellow tones, nourish the hair fiber and protect it from external aggression.

Why is blonde hair so demanding?

It all starts with its pigmentation. Natural blonde hair contains little melanin, the pigment that gives hair its colour and also protects it. The hair fibre is therefore more exposed to external aggression, becoming more vulnerable to oxidising agents (UV rays, chlorine, heavy metals, etc.). This weakens the structure of the hair fibre, making it more porous, and dulling blonde hair’s shine.

In the case of bleached blonde hair, the hair fibre is doubly weakened: 

By chemical treatments

which alter hair’s internal structure

By the disappearance of melanin

which deprives hair of its natural protection against oxidation.

More vulnerable, it becomes rough to the touch and prone to unwanted tones. Whether natural or bleached, blonde hair is therefore more fragile and requires a blonde hair routine that both maintains colour and strengthens the hair fibre.

Which blonde hair care ritual should I use?

Step 1: Washing blonde hair

The first step in a successful blonde hair routine: gentle washing. Blonde hair is more porous and cannot tolerate harsh formulas. A nourishing shampoo gently cleanses the scalp and hair fibre, without irritating them. If hair has other specific concerns (excess sebum, dandruff, hair loss, etc.), it is perfectly possible to alternate the shampoos as needed, to treat each concern without compromising blonde hair’s beauty.

Step 2: Treating and enhancing blonde hair

Once or twice a week, give your hair a deep conditioning treatment tailored to its type and colour. This is an essential step in maintaining hair’s shine and suppleness.

- For bleached or highlighted blonde hair, a purple mask is ideal for correcting yellow tones, reviving the purity of blonde colour and caring for the hair fibre. Alternate with a nourishing mask to nourish and repair hair deep down.

- For natural blonde hair, choose a nourishing mask rich in strengthening and repairing active ingredients to intensely nourish the hair fibre.

Step 3: Protect blonde hair on a daily basis

Protection is the final (but essential!) step in the blonde hair routine to prevent the effects of external aggression on hair fibre quality and colour.


- Before styling: apply a thermo-protective product to limit the effects of using a hairdryer or straighteners.

- As a finishing touch: apply a few drops of nourishing oil to the lengths to nourish, smooth and illuminate hair.

- Before going out: spray a protective product to shield the hair fibre against UV rays, pollution, humidity, salt and chlorine.

Your questions about blonde hair care


How do I neutralise yellow tones in blonde hair?

Yellow tones often appear as a result of oxidation. To correct them, we use hair care products containing purple pigments, because purple sits opposite yellow on the colour wheel and therefore neutralises it. Whether a mask or shampoo, this type of product is used once or twice a week to revive colour purity.

How do I take care of very dry blonde hair?

To restore strength and suppleness to very dry hair, alternate nourishing and repairing hair care. Whenever possible, space out your washes to preserve the hair fibre's protective film, and always rinse your hair with cold water to help seal the cuticles and restore shine.

How do I protect blonde hair from the sun?

The sun accelerates yellowing of bleached and highlighted blonde hair and weakens the hair fibre. Before any sun exposure, apply a product that protects against UV rays, heat, chlorine and salt. At the beach, wear a hat or tie your hair back to limit friction, and remember to rinse it in clean water after each swim.

What is the best routine for maintaining icy blonde hair?

Obtained by successive bleaching treatments, icy blonde is one of the most demanding blondes. Almost devoid of pigments and protective melanin, the hair fibre is particularly sensitive to external aggression. To maintain its purity, alternate a purple mask with nourishing or restructuring hair care to strengthen the hair fibre. Limit heat sources, favour rich textures and long application times, and protect your hair from the sun, salt and chlorine as a matter of course. This consistent approach maintains the balance between neutralisation, repair and shine.

What should I avoid with blonde hair?

For radiant blonde colour and a healthy hair fibre, avoid harsh shampoos, overly frequent washing and high-temperature heat styling tools. Gentleness and protection are key in an effective blonde hair routine.


Taking care of blonde hair on a daily basis is based on three key steps: neutralising yellow tones, nourishing the hair fibre and protecting hair every day. With the right care and consistency, colour remains luminous, and hair stays supple and shiny.
