Keratinbehandling hemma — den kompletta guiden 2026

A keratin treatment at home gives you smooth, shiny and frizz-free hair without paying SEK 2,500–4,000 at a salon. More and more Swedes are choosing to do the keratin treatment at home, and with the right products, the results are basically indistinguishable from a professional treatment.

This guide goes over everything you need to know about at-home keratin treatments: what products you need, how to do it step by step, common mistakes that ruin the results, and how to make your treatment last up to five months. We use Cocochoco's formaldehyde-free products throughout the process.

What is a keratin treatment and why do it at home?

A keratin treatment fills out the hair's structure, smoothes the cuticle and seals the entire hair shaft. The result is frizz-free hair in humidity, rain and heat, up to 60 percent less blow-drying time in the morning, mirror-like shine that lasts three to five months, and protection from sun, wind, salt and chlorine.

Getting a keratin treatment at home has become popular for three reasons. It's significantly cheaper than going to the salon. You can do it when it suits you. And with Cocochoco's professional products, you get the same results as a hairdresser would give you.

The only catch is that you have to do it right. Skip one step and the results will last three weeks instead of three months. This guide will take you through the entire process.

How long does a keratin treatment at home take?

Expect two to three hours from start to finish for medium-length hair. Long, thick hair will take longer. Plan your time and don't rush through the steps. This is where most mistakes happen.

This is what you need from Cocochoco

Cocochoco Clarifying Shampoo for deep cleansing before the treatment. Cocochoco keratin treatment in the variant that suits your hair (Original, Gold 24K, Pure or Onyx). Cocochoco Sulfate-Free Shampoo and Sulfate-Free Conditioner for aftercare. A straightening iron that can withstand at least 230 degrees, a brush, a bowl, hair clips and a fine comb.

Step by step: how to do a Cocochoco keratin treatment at home

Step 1: Wash your hair twice with Cocochoco Clarifying Shampoo

Deep cleansing is essential. Clarifying Shampoo dissolves silicones, minerals and product residue that prevent keratin from adhering. Rinse thoroughly and do not use conditioner afterwards.

Step 2: Blow dry your hair completely.

Hair must be 100% dry before applying the keratin. Moisture prevents bonding. Use lukewarm air, not hot.

Step 3: Comb through and divide into sections

Divide your hair into four to six sections with clips. This will ensure even application and no missed areas.

Step 4: Apply the keratin with a brush

Apply thinly and evenly, two centimeters from the scalp down to the ends. Wear gloves. Thin layers work better than thick ones.

Step 5: Leave on for 20–30 minutes

Follow the time for your specific Cocochoco variety. Too short a time and the result will be weak. Too long and you risk the product drying out.

Step 6: Blow dry again

Blow dry the hair completely with hot air. This activates the keratin prior to sealing.

Step 7: Seal with straightening iron

Flatten each small section seven to ten times at at least 230 degrees. This is the seal that locks the keratin in. If you skip or go too fast here, you will lose the durability of the treatment completely.

The first 72 hours — this is hot

For the first 72 hours after treatment, your hair should not be wet, put up or exposed to moisture. No hair bands, no clips, no sweat from training, no shower without a swimming cap. This is the single most important rule for the results to last.

Common mistakes that ruin at-home keratin treatments

These are the ten most common mistakes people make when doing keratin treatments at home. Avoid them and you'll get results that last for months.

Skip the Clarifying Shampoo. The hair is not clean enough and the keratin does not adhere properly.

Use conditioner before the treatment. Conditioner creates a layer that completely blocks the keratin.

Apply to damp hair. Water prevents the bonding and you lose the effect.

Apply too close to the scalp. It will be sticky and heavy at the roots without giving better results.

Apply too much product. Thin layers work better than thick ones. You'll just waste it if you click on more.

Skip sectional division. You will miss games and get uneven results.

Too short an exposure time. The keratin does not have time to penetrate the hair shaft.

Too low a straightening iron temperature. Below 230 degrees the keratin does not seal properly.

Flatten too few times per section. Seven to ten strokes is the minimum.

Wash your hair too soon. The 72-hour rule is there for a reason. Break it and you could be throwing away the entire treatment.

How to make your keratin treatment last five months

Always use sulfate-free shampoo and conditioner. Regular shampoo breaks down keratin in half the time. Cocochoco Sulfate-Free Shampoo and Sulfate-Free Conditioner are formulated specifically for keratin-treated hair.

Wash your hair a maximum of twice a week. More than that will unnecessarily strain the treatment.

Do not use hard water directly on your hair. Minerals build up and weaken the effect.

Protect your hair from chlorine and salt water. Spray Cocochoco Diamond Drops before swimming in the pool or ocean.

Use Cocochoco Keratin Repair Mask once a week. This will significantly prolong the effect of the treatment.

Can the treatment withstand summer, the beach and the pool?

Yes, if you protect your hair. Always rinse your hair with clean water before going into the pool or ocean. Use Diamond Drops as a protective barrier. Rinse immediately after swimming and use sulfate-free shampoo.

When not to get a keratin treatment

If you are pregnant or breastfeeding. If your hair has been very recently bleached or colored (wait at least two weeks). If your scalp is damaged or irritated. If you are allergic to any of the ingredients.

For sensitive or bleached hair, choose Cocochoco Pure which is the gentlest variant.

Which Cocochoco variant should you choose?

Original is suitable for most hair types and is a safe first choice. Gold 24K is our premium variant with real gold and is suitable for thick and strong hair. Pure is the gentlest and perfect for sensitive, bleached or colored hair. Onyx is our strongest variant for very frizzy and unmanageable hair.

For those of you who are new, we recommend starting with Cocochoco Original. It is forgiving, gives great results and is easy to apply even for the first time.
