The basic routine: what order to use products in

An effective routine only needs a few steps, in the right order:

1. Shampoo — cleanses scalp and lengths. It should be chosen based on your scalp (oily, dry, sensitive, dandruff-prone), not on your hair lengths.
2. Conditioner (also called balsamo) — seals the cuticle after washing, detangles and reduces breakage. Apply only from mid-length down, never on the scalp.
3. Hair mask — intensive treatment, 1-2 times a week. Leave on for 10-15 minutes. Replaces conditioner, they shouldn't be used together in the same wash.
4. Serum or oil — leave-in, on damp or dry hair. Seals the cuticle and protects against heat from hairdryers and straighteners.
5. Styling — cream, mousse, gel or hairspray, depending on the hold you want.

General rule: shampoo on the scalp, everything else on the lengths.

Which shampoo to choose

• Oily hair — purifying or sebum-normalising shampoo, frequent washes but with gentle formulas. Conditioner only on the ends.
• Dry hair — nourishing shampoo with vegetable oils, gentle surfactants, weekly mask.
• Fine hair — light volumising formulas. Avoid heavy oils and butters that weigh down the roots.
• Curly hair — hydrating shampoo without harsh sulphates, generous conditioner, products based on shea butter.
• Colour-treated hair — specific shampoos that respect the acidic pH and limit colour fade.
• Blonde hair — anti-yellow shampoo with purple pigments, alternated with a neutral shampoo.
• Dandruff — shampoo with specific anti-fungal actives, 2-3 times a week.

Frizzy hair: what actually works

Frizz is almost always a hydration problem: the raised cuticle absorbs moisture from the air and the hair swells up. So the solution is to hydrate and seal.

Hydrating shampoo, weekly mask, and above all a leave-in product on damp hair (cream, serum or oil) before drying. Heat protection isn't optional: without it, blow-drying makes frizz worse every time. Dry with a diffuser on medium heat and don't touch your hair until it's completely dry.

Colour-treated and dyed hair: how to make colour last

• Wait 48-72 hours after colouring before the first wash.
• Wash with lukewarm water, never hot: heat opens the cuticle and fades the pigment.
• Use shampoos specific for colour-treated hair, with an acidic pH.
• Weekly mask to make up for the dehydration caused by colouring.
• Sun protection for hair in summer: UV rays oxidise the pigment.
• On blonde and bleached hair, alternate with an anti-yellow colour shampoo.

For professional colouring, bleach and oxidising emulsions, a dedicated price list is available for professionals.

Colour shampoo and colour bath: the differences

A colour shampoo deposits pigment on the surface of the hair without penetrating the cortex. It contains no ammonia or oxidant, doesn't lighten, and fades gradually over 4-8 washes. Useful for refreshing a colour or trying out a shade before committing to it.

A colour bath is a semi-permanent, acidic-pH colouring treatment, without ammonia. It lasts longer (around 20-25 washes) and gives shine, but doesn't cover grey hair 100% and doesn't lighten.

Permanent colouring requires an oxidant, penetrates the hair fibre, covers grey hair and can lighten by a few tones.

Leave-in treatments

A serum has a light, concentrated formula: a few drops are applied to damp or dry lengths, sealing the cuticle and protecting against heat. Oil is richer and suited to thick, curly or very dry hair. Sprays and vials are lighter and suited to fine hair.

On fine hair, 2-3 drops are enough, only on the ends. On curly hair you can be more generous, spreading it with open hands over the wet lengths.

Frequently asked questions

Are conditioner and balsamo the same thing?

Yes. They're two names for the same product: a post-shampoo treatment with an acidic pH that seals the cuticle and detangles. They shouldn't be used one after the other.

How often should you wash your hair?

It depends on the scalp, not the lengths. Oily scalp: even every day, with a gentle shampoo. Normal scalp: 2-3 times a week. Dry scalp: 1-2 times. Washing more often doesn't increase sebum production, that's a myth.

Can you use a mask and conditioner together?

There's no need: they perform the same function, with the mask doing so more intensively. Use the mask instead of conditioner on washes where you need a richer treatment.

Are silicone-free products better?

Not necessarily. Silicones improve slip and shine and protect against heat. Non-water-soluble ones can build up on fine hair and weigh it down, and are removed with a purifying shampoo every 2-3 weeks. On curly or very damaged hair they're often useful.

How often should you use a hair mask?

Once a week for normal hair, twice for dry, colour-treated or bleached hair. Leave on for 10-15 minutes: longer times don't increase effectiveness.

How do you protect hair from hairdryers and straighteners?

Always apply a heat protectant on damp hair before drying. Keep the hairdryer 15-20 cm away and don't use straighteners on hair that isn't completely dry: residual water evaporates abruptly and damages the hair fibre.
