Classic technique

What is Nano Keratin hair?

Nano Keratin hair is an extension technique made with small strands applied one by one. The objective is to create length, volume, or fullness through individual application points.

Nano Keratin allows working on specific areas of the head: sides, nape, contour, filling in ends, and areas where hair needs to blend better. Furthermore, it is a technique that has existed for over half a century, still chosen by those who value traditional methods and do not give up on nostalgia.

In practice, the final quality depends on four factors: good quality human hair, a well-chosen colour, the right amount of grams, and professional application. When one of these points fails, the extension can become heavy, noticeable, with thin ends, or difficult to maintain.

What is the history of Nano Keratin?

Nano Keratin gained popularity because it allowed strand-by-strand applications at a time when the market had fewer light and flexible alternatives. Today, it continues to exist as a traditional technique, but it needs to be chosen consciously: the weight, maintenance, and quality of the application determine whether the result will be comfortable or detrimental to the natural hair.

What should the client know before buying?

Buying hair is only one part of the result. Before choosing, it is important to know if your hair can withstand the technique, what length suits your height, how many grams are needed to avoid thin ends, and if the chosen colour disappears into your hair in natural light.

Diagnosis before purchase

Who is Nano Keratin indicated for?

The technique can make sense for those looking for a strand-by-strand application and who accept professional maintenance. But the choice should consider hair health, routine, applied weight, and the fact that it is a traditional method, older and less flexible than more modern techniques.

For natural lengthening

It can be considered when the client wants to increase length with application by small strands. It works best when natural hair has enough structure and when the application is done with controlled weight.

To fill in ends

It can help with localised filling, such as sparse sides and ends, as long as the professional assesses the natural hair's resistance and avoids excessive tension.

For a personalised result

By working strand by strand, it requires careful application. The distribution must respect density, contour, natural hair fall, and the client's hair limits.

Attention before applying

If your hair is very fragile, brittle, elastic, experiencing intense shedding, or sensitised by recent chemical treatments, confirm with a professional before choosing any fixed technique.

Technical choice

Nano Keratin, Tape, Weft or Clip-In?

The best technique is not the most famous or the oldest. It is the one that respects hair health, the client's routine, natural density, and the expected result.

Technique Best for Strong point When to avoid
Nano Keratin Those who want a traditional strand-by-strand technique and accept professional maintenance. Allows working on specific areas, but requires weight and tension control. If you don't want professional maintenance, have fragile hair, or are looking for the most modern and lightest option.
Invisible Slim Tape Fine to medium hair that needs lightness and a flat base. Discrete, fast, and comfortable application when well distributed. Very oily roots without an adequate care routine.
Weft Hair Professional transformations with significant volume and length. Versatility for professionals and full results. If you want to apply and remove them yourself at home.
Clip-In Events, photos, visual tests, and temporary use. Apply and remove at home, with no fixed commitment. If you intend to sleep, exercise, and wear extensions every day.

Right quantity

How many grams of Nano Keratin to buy?

Buying too little hair can leave the ends sparse. Buying too much can be heavy. The ideal decision considers your natural hair, current length, desired length, and density of the ends.

1

50 g

For small fillings, sides, colour tests, or very subtle volume in fine hair.

2

100 g

A good base for light volume, fuller ends, or subtle lengthening when natural hair already has a similar length.

3

150 g

Balanced choice for many clients who want visible lengthening with a natural result.

4

200 g

Recommended for a bigger transformation, dense hair, blunt cut, or when the length difference is significant.

Your case Likely quantity Important note
Fine hair and only want to fill 50 g to 100 g The focus is on good distribution to avoid weighing down the roots.
Medium hair and want to lengthen 100 g to 150 g If the cut is very blunt, you may need more hair.
Dense, short, or voluminous hair 150 g to 200 g More grams help avoid a step between natural hair and the extension.
Complete transformation 200 g or professional assessment The longer the chosen length, the more important it is to maintain full ends.

Perfect colour

The right colour is the one that disappears in your hair

With Nano Keratin, the colour needs to blend well because the strands are distributed throughout the hair. The most common mistake is choosing based on the product photo, without comparing it with the ends in natural light.

How to analyse the colour before buying

  • Observe the hair in natural light, without filters and without yellow light.
  • Mainly compare the ends, because that's where the extension is most visible.
  • If you have highlights, assess if you need a multidimensional tone or a mix of colours.
  • For blondes, confirm undertone: golden, beige, pearl, cool, or warm.

When to ask for help

If you are between two colours, have smudged roots, balayage hair, very light blonde, illuminated brown, or ends with different reflections, confirm with support before purchasing.

Maintenance and durability

How to care for Nano Keratin to make it last longer

Durability does not depend solely on the hair purchased. It depends on the application, maintenance, washing, brushing, heat, products, and daily routine.

When washing

Wash carefully, without aggressively rubbing the roots. Avoid excess oily product near the application points and rinse thoroughly.

When drying

Do not sleep with wet hair. Dry the roots and application points thoroughly to maintain comfort, hygiene, and finish.

When brushing

Use an appropriate brush, detangle the ends first, and gradually work your way up. Hold the roots to avoid unnecessary tension.

Beautiful extensions are not a promise. They are diagnosis, appropriate technique, and constant care.

If you choose Nano Keratin, treat the decision responsibly: confirm the correct quantity, respect the health of your natural hair, and apply only with an experienced professional.

Frequently asked questions

Common questions about Nano Keratin

These answers help customers decide more confidently before buying hair for Nano Keratin application.

Does Nano Keratin damage hair?

The technique should be evaluated as a whole: application quality, weight, maintenance, and the condition of natural hair. When poorly applied or too heavy, any fixed technique can cause traction.

Can I apply it to fine hair?

It may be possible, but requires professional assessment. Fine hair requires careful distribution, less weight, and correct maintenance.

How many grams should I buy?

For light volume, 50g to 100g may suffice. For a visible extension, many customers need 100g to 150g. For a complete transformation, 200g may be more suitable.

Which size to choose?

40 cm to 50 cm looks more natural and discreet. 55 cm to 60 cm creates a visible transformation. 65 cm to 70 cm creates a long and glamorous effect, but requires more grams and care.

Can I use a flat iron or curling iron?

Since it's human hair, you can style with heat, but use heat protectant and avoid excessive temperature, especially near the application points.

Can I sleep with Nano Keratin?

Yes, as it is a fixed technique, but do not sleep with wet hair. Tie it lightly and maintain a brushing routine to avoid tangles.

How to choose the color?

Compare the extension with the ends of your hair in natural light. If you have highlights, a shadowed root, or a specific undertone blonde, confirm with support beforehand.

Nano Keratin or Clip-In?

Clip-In is for temporary, at-home use. Nano Keratin is for those who want a fixed professional application, with point-by-point distribution.

Do I need a professional to apply it?

Yes. Nano Keratin should be applied by a professional to ensure correct root distance, amount per strand, distribution, and maintenance.

Does StoreKHair deliver to Europe?

Yes. StoreKHair offers tracked shipping and professional support to help with selection before purchase.
