FREQUENT QUESTIONS:

1. INVISIBLE INJECTED TAPE HAIR QUALITY

nais hair extensions warranty

As they are REMY quality extensions, the tips and roots go in the same direction, therefore preventing the hair from tangling. They preserve all their natural elements and original texture as well as their cuticle intact , which allows a much longer duration (4 times longer) than extensions of low quality and price.

The hair does not suffer loss or fall from its headband, especially thanks to the reinforced double micro-stitching system. The adhesion to your hair is extremely resistant due to its thin surgical adhesive tape.

Due to the proven quality of our tape extensions, you can enjoy them for up to 18 months while retaining their natural shine, hydration, silky texture... We select the quality of our hair very demandingly.

2. WHAT IS THE PRICE OF THE 4k INVISIBLE TAPE EXTENSIONS?

The cost of 4k invisible adhesive hair extensions depends on the length and volume of hair you want to achieve, but their price ranges between 140 and 170 $/€ for a package of 20 pieces.

We recommend at least 2 packages of 50 grams each to achieve an incredible volume effect, or 3 packages if your hair is short or you want more additional volume. We have different measurements: 20 inches (50cm) for a medium length and 24 inches (60cm) if you want extra long.

Our 4k invisible tape-in ​​hair extensions can be waved, flat-ironed, curled, straightened, and even dyed just like you would your own hair.

They can also be bleached , but remember that by bleaching you will greatly reduce the length of the hair, so we always recommend when in doubt to choose a slightly lighter color and darken it with a simple color bath if you wish, it would always be a better option than bleaching. However, most of our clients do not need to dye their hair because we offer a sufficiently wide variety of colors.

3. HOW MUCH HAIR DO I NEED FOR A FULL HEAD?

The price of the full mane may vary depending on several factors. The first thing you have to consider is how much hair volume you want and how long your hair is . If you want a discreet amount of volume and your hair is long, 100 grams of extensions could be enough. However, you will need more extensions if you want very voluminous hair that stands out. And if your own hair is short you will need something more, perhaps 200 grams or more.

This means that the price of tape extensions can range between 200 to 600 dollars or euros. This will depend on the look you want to achieve. Think about a long-term investment that can last more than 1 year while maintaining shine and softness.

Other types of permanent extensions could damage your hair, especially if they are not placed correctly. But tape extensions are the most recommended for people with thin and sparse hair .

9. CAN I USE 4k INVISIBLE ADHESIVE EXTENSIONS ON SHORT HAIR?

Tape extensions do not damage the hair. Therefore, anyone can use tape-in ​​extensions , even if they have fine and delicate hair. Also in short hair, taking into account that you will need more volume to achieve a large volume effect.

However, people with serious hair loss problems should not use any type of extensions until their condition improves.

For very curly or afro-style hair, adhesive extensions are not the most suitable. In that case, it is better that you choose other types of extensions, such as sew-in extensions .

Tape-in ​​extensions are an excellent option for girls who have a very active life. For those who want fixed extensions without having the hassle of putting on and taking off removable extensions such as clip-on or invisible thread extensions every day .

10. PLACEMENT OF INVISIBLE 4K HAIR EXTENSIONS

Placing adhesive hair extensions is much easier than it seems. Placement time can be between 30 and 45 minutes depending on your skill and the amount of volume you want. But it is important that you follow the technical steps for good placement to prevent the adhesive from coming off after a few washes .

You can ask your beauty salon for help or place them yourself with the help of a friend and this video tutorial:

placing adhesive extensions step 1
  • STEP 1 : Take 2 pieces of the 20 that come in the package, and remove the paper from the adhesive tape.
  • STEP 2 : Place one piece of the extension on top of your hair and another on the bottom, leaving a strand of your hair in the middle like a sandwich, and leaving about 2 millimeters of space between the extension and the root of your hair. hair to avoid
    tension to your hair.
  • STEP 3 : It is very important that the amount of your own hair that you leave in the middle is not too much because it reduces the adhesion surface.
    Don't take too little hair either because you need quite a few hairs, not just a few, to act as a hold for the extension.
placement of adhesive extensions step 2
  • STEP 4 : Once the first "sandwich" is made, heat the joint for only about 5 seconds with your hair straightener at medium temperature. This is to slightly melt the adhesive and multiply the bond strength.
  • STEP 5 : Squeeze the “sandwich” with pressure pliers to further enhance adhesion.
  • STEP 6 : Repeat the same operation by gluing pairs of extension strands evenly on the nape and sides.

11. How are they put back?

11. HOW TO REPLACE INVISIBLE ADHESIVE EXTENSIONS WITHOUT MISTREATING YOUR HAIR

Our 4K adhesive extensions are completely reusable. You can put them back as many times as you want. Many of our clients remove and replace them up to 5 or 6 times.

Every 2 or 3 months your hair grows approximately 1 centimeter, so you will need to "upgrade" your extensions. You will only need our exclusive organic solvent for extensions , to clean the adhesive base naturally and keep your extensions in perfect condition. This solvent is made with natural citrus fruits and without any type of aggressive chemicals or acetones, allowing you to avoid any type of damage to both the hair and the headband. Replace the adhesive tape again, finish with a simple rinse with warm water and that's it.

You can wash your hair as you normally do. However, do not apply oily products to the joints where the adhesive is . That could also weaken the power of the adhesive and cause them to peel off prematurely. Therefore, if you use a mask, apply it only from the mid-lengths to the ends.

12. HOW LONG DO REMY QUALITY TAPE ADHESIVE 4K EXTENSIONS LAST?

Nais Hair hair is real remy and lasts between 12 and 18 months . This is very important that you understand because the word remy has already degraded to being a simple term to identify natural hair, and this is in the best of cases.

The reality is that 95% of the hair sold on the market does NOT have a cuticle , no matter how much they advertise it, the majority does not have a cuticle. You can do the test by simply taking a hair and sliding it up and down, and if you don't notice friction when you move your fingers up, you can be sure that it doesn't have a cuticle.

The reason is because it is made with waste hair raw material from hair salons, and to prevent it from getting tangled, the cuticle must be removed. But hair without a cuticle is dead hair, dry hair without the natural protection of the hair. It is cheaper hair, but since it does not have the natural protection of the cuticle, even if they put a wax bath on it to give it shine, in the first wash it loses its shine, and even if you tried to revive it with the best shampoo and conditioner, that hair has suffered a lot and will never look bright and healthy.

Nais Hair invisible adhesive extensions actually have the cuticle intact. The raw material used is hair from healthy donors , and not hair salon waste. And they have been manufactured with a slow, cold discoloration process, similar to osmosis.

Please invest in your beauty in quality products , and don't get carried away by appearances. The difference in price is not big compared to other cheap extensions, but the difference in durability is 4 times more.

The well-known saying “cheap is expensive” is true in a very special way in the world of extensions. In reality, the savings, compared to other types of extensions, are in the placement.

Enjoy your extensions for longer, and healthy, shiny and soft extensions .

10. How long do they last?

HOW LONG DOES TAPE-IN HAIR EXTENSIONS LAST FOR?

Nais Hair tape extensions are real Remy with cuticle and last between 12 and 18 months . There are clients who have used it permanently for more than 3 years. This is very important that you understand because the word Remy has already degraded to being a simple term to identify natural hair, and this is in the best of cases.

Currently, 93% of the hair sold on the market does NOT have a cuticle, no matter how they advertise it, the majority of hair in extensions does not have a cuticle. You can do the test by simply taking a hair and sliding it up and down, and if you don't notice friction when you move your fingers up, you can be sure that it doesn't have a cuticle.

But the difference is abysmal both in the purity of the color, as well as the duration and the healthy appearance. The first impression is that it is a coarser hair than Remy. This is because hair without cuticle does not have a layer of wax but rather the original feel of the hair itself. The client who tries hair with cuticle will no longer accept remy hair WITHOUT cuticle because she will learn to appreciate the difference.

Why do they remove the cuticle to manufacture 93% of the extensions on the world market? The reason is because it is made with waste hair raw material from hair salons, and to avoid tangles they must remove the cuticle and turn it into hair without shape or trend. But hair without a cuticle is dead hair, dry hair, that has lost its original structure and without the natural protection of the hair. It is cheaper hair, but since it does not have the natural protection of the cuticle, even if they put a wax bath on it to give it shine, in the first wash it loses its shine, and even if you tried to revive it with the best shampoo and conditioner, that hair has suffered a lot and will never look bright and healthy.

Nais Hair adhesive extensions actually have the cuticle intact. The raw material used is hair from healthy donors , and not hair salon waste. And they have been manufactured with a slow, cold bleaching process, similar to osmosis.

Please invest in your beauty in quality products , and don't get carried away by appearances. The difference in price is not big compared to other cheap extensions, but the difference in durability is 4 times more.

The well-known saying “cheap is expensive” is true in a very special way in the world of extensions. In reality, the savings, compared to other types of extensions, are in the placement.

Enjoy your extensions for longer, and healthy, shiny and soft extensions.
