StoreKHair signature technique
Hiperflex Method, created by Kathleen Campos
Hiperflex is StoreKHair's main technique for those who want to use extensions without sacrificing the health of their own hair. It was created by Kathleen Campos after years of experience with chemistry, colorimetry, and extensions, focusing on preserving natural hair and allowing it to continue to grow healthily during use.
Why does it protect natural hair?
The method was designed to distribute the weight of the extension more safely, reduce tension at the root, and avoid aggressive traction. This way, the client can use longer and fuller hair while preserving the structure of their own strands.
When to choose it
Choose Hiperflex when you want a fixed, comfortable, and professional technique, but are afraid of hair loss, breakage, thinning, or damage caused by heavy methods. The right choice should leave your hair beautiful now and healthier in the future.
- Preserves natural hair
- Stimulates healthy growth
- Less traction at the root
- Comfort in daily use
- Professional application

The right method
Choose in 4 simple decisions
Before buying, answer these four questions. They define whether the hair will look natural, comfortable, and beautiful in everyday life.
1
What is your goal?
Subtle volume, full lengthening, transformation for an event, or daily use. The objective defines grams and technique.
2
What is your natural hair like?
Fine, fragile, bleached, dense, or oily hair requires different techniques to protect the root and ensure comfort.
3
What maintenance are you willing to do?
Clip-in can be applied at home. Tape, weft, and nano-keratin require professional application and scheduled maintenance.
4
Does the color fit in real light?
The best color is not the most beautiful in isolation: it's the one that disappears into your hair in natural light, root and ends.
Quick choice

Right quantity
How many grams to buy?
The ideal quantity depends on your hair density and the desired result. When in doubt, choose with support: buying too little creates empty ends; buying too much can be heavy.
100g
For light volume, subtle filling, or fine hair. Good option when natural hair already has a similar length.
150g
The balance point for many clients: visible volume, fuller ends, and a natural result for everyday wear.
200g
For a complete transformation, lengthening with plenty of density, or thicker natural hair.
| Your case | Recommended quantity | Important note |
|---|---|---|
| Fine hair and only want volume | 100g to 150g | Prefer light techniques and distribute the weight well to protect the root. |
| Medium hair and want to lengthen | 150g to 200g | If your cut is very straight, you may need more hair to blend the ends. |
| Dense, short hair, or with a distinct cut | 200g or more | The goal is to avoid a visible difference between your hair and the extension. |
| Hiperflex result with hair preservation | Defined by technical evaluation | The quantity depends on distribution, natural density, and desired finish. |
Simple rule to get it right
If you just want to fill in, think about volume. If you want to lengthen, think about volume + length. The greater the difference between your current hair and the desired result, the more grams will be needed for the ends to be full.
Perfect color
The ideal color is the one that disappears in your hair
Always compare root, mid-lengths, and ends in natural light. If your hair has highlights, balayage, or shadowed roots, a multi-dimensional color or a blend of shades might be the best choice.
- Take photos and analyze them from the front, back, and side in natural light, without a filter.
- Look closely at the roots and ends: often they have different shades.
- If you are between two colors, choose with support before finalizing.
- For blonde or bleached hair, confirm the undertone: golden, beige, pearl, cool, or warm.

| Color doubt | How to decide | Common mistake |
|---|---|---|
| I'm between two colors | Always compare with the ends, not just the roots. The extension is more visible at the ends. | Buying based on the prettiest photo on the website, without comparing in natural light. |
| I have highlights or balayage | Choose a blended shade, shadowed roots, or confirm if you need to combine two colors. | Choosing a uniform blonde when natural hair has several reflections. |
| My hair is blonde | Identify undertone: golden, beige, pearl, platinum, cool, or warm. | Buying "light blonde" without realizing if your blonde is warm or cool. |
| My hair is brown | Observe if it leans towards chocolate, coppery, espresso, natural, or highlighted. | Choosing a very dark brown and creating an artificial contrast. |
Need a very specific color?
For blondes, highlighted, ombre hair, or shades that don't perfectly fit a ready-made color, StoreKHair offers the option to customize the hair. First choose size, then grams, and finally the desired technique and color.
Size and finish
How to choose the length without making a mistake
The length should match your height, current cut, and density. The longer the chosen hair, the more important it is to have enough grams to avoid thin ends.
45-50 cm
Ideal for naturalness, volume, and discreet lengthening. Usually falls below the shoulders or mid-back, depending on your height.
55-60 cm
Most desired length for a visible transformation, maintaining elegance and ease of care.
65-70 cm
Long and striking result. Requires more grams and more care discipline to maintain beautiful ends.
Over 70 cm
High-impact look, suitable for those who want a glamorous effect and accept higher maintenance.
Decision shortcut
If your natural hair is above your shoulders and you want to reach mid-back, choose more grams. If your hair is already long and you just want full ends, you might need less quantity.
If you're in doubt between two options, don't buy blindly.
The ideal hair should be chosen with technique, not impulsively. StoreKHair can help confirm color, grams, and method before purchase, so the result looks natural from the first application.
Confirm before buyingDecision by profile
Choose by your current moment
The best purchase is one that adapts to your real life: time, maintenance, at-home skill, and expected result.

Before finalizing the purchase
These answers address the most common doubts before the first purchase of human hair extensions.
Can I use heat on the hair?
Yes. As it is human hair, you can style it with a flat iron, curling iron, or hairdryer. Always use heat protectant and avoid excessive temperatures.
Which length should I choose?
If you want naturalness, choose a length that matches your cut. For transformation, ensure enough grams so the ends don't look sparse.
Do extensions damage hair?
The correct technique, applied with adequate weight and proper maintenance, protects much more than a choice made without guidance.
What if I choose the wrong color?
Before buying, send photos in natural light to the team. Color confirmation is the simplest way to avoid exchanges and frustration.
How long does it last?
Durability depends on routine, technique, maintenance, and care. With good care, premium human hair can accompany the client for many months.
Which technique is most invisible?
It depends on the root and hair density. Invisible Slim Tape, Nano-Keratin, and well-distributed professional applications tend to be very discreet.
When should I choose the Hiperflex Method?
Choose Hiperflex when you want a professional application focused on preserving natural hair, reducing root tension, and allowing hair to continue growing more safely while wearing extensions.
Clip-In or Hiperflex?
Clip-In is for temporary and self-use. Hiperflex is for those who want a fixed professional technique focused on protecting natural hair while using lengthening or volume.
100g, 150g or 200g?
100g is for minor filling. 150g is the balanced option for many clients. 200g or more is indicated for greater lengthening, dense hair, blunt cuts, or results with very full ends.
How do I know if I need more hair?
If your hair is short, thick, heavily layered, or has dense ends, you typically need more grams for the extension to blend without creating a step.
Can I dye or tone it?
Since it's human hair, technical adjustments may be possible, but should be done by a professional. We never recommend home bleaching or changing color without a strand test.
How do I care for it after purchase?
Use moisturizing products, heat protectant, an appropriate brush, correct root drying if there's a fixed technique, and avoid sleeping with wet hair.
Still have questions?
Even with the complete guide, final confirmation can prevent mistakes in color, quantity, or technique. Send photos in natural light and state your desired result.
