Discover your hair’s needs today—for the well-being of your hair and to save time in your morning routine.

Why perform a hair diagnostic?

Your hair tells much more than just a styling story: its texture, shine, and movement reflect its unique nature. A hair diagnostic is the art of reading between the strands to reveal what makes them magnificent.

By precisely identifying its characteristics, you create the foundation for a personalized hair routine that highlights its full radiance. This precise step guides you toward the most harmonious care and accessories, while supporting your hair's evolution through the seasons, your habits, and your desires. It is the ideal starting point for a hair ritual that enhances your natural beauty.

Understanding your hair’s nature

Every head of hair is unique and is defined by several characteristics that, together, form its identity. Knowing them opens the way to targeted care and respectful styling.

Understanding your hair involves observing:

Texture: Fine, medium, or thick—it influences the volume and sensitivity of the fiber.
Shape: Straight, wavy, curly, or coily—it guides the choice of techniques and accessories.
Density: The number of hairs per square centimeter determines the perception of volume.
Porosity: Low, medium, or high—it indicates the hair’s ability to absorb and retain moisture.
Scalp Condition: Balanced, dry, or oily-prone—it plays a key role in the overall health of the lengths.

Observing and analyzing these parameters allows you to choose accessories that reveal all the natural beauty of your hair while respecting its balance.

Adapting your care and accessories

A personalized hair routine is like a tailor-made wardrobe for your hair: it adjusts to its texture, density, and daily condition. To compose it, everything starts with an adapted hairbrush that respects the fiber.

Your hair will be enhanced by care designed for its condition, type, and your environment (humidity, diet, pollution, heat). Target your needs with precision: adapted products (shampoo, mask, treatment) and quality accessories (eco-designed comb, hairbrush).

Once the importance of the diagnostic is understood, the next step is knowing how to apply it daily: let's discover the simplest and most effective methods for analyzing your hair.

How to perform an effective hair diagnostic?

Your hair deserves the same attention as your skin during your skincare routine. A home hair diagnostic or an online hair diagnostic is the first step toward building a personalized hair routine adapted to your nature.

The more you know your lengths and your scalp, the more you can offer them what they truly love. Whether it’s a quick self-diagnostic or a free hair test, the goal remains the same: understand, adapt, enhance.

At home: simple steps

Performing a home hair diagnostic takes only a few minutes and requires only a mirror… and a bit of curiosity. Here is how to become an expert on your own hair:

Observe it: Shine, volume, suppleness.
Touch to understand: A soft strand has received what it needs; a rough strand is calling for more care.
Test the porosity: Drop a clean hair into a glass of water.It floats → low porosity, it retains moisture well.It sinks → high porosity, it absorbs care quickly but loses it just as fast.
Analyze the scalp: Is it dry, sensitive, balanced, or oily-prone?

In just a few steps, this DIY hair test guides you toward the right products—from shampoo to mask—and toward the most respectful styling accessory for your fiber.

Professional tools used

Want to go further? A professional hair diagnostic offers an ultra-precise reading of your fiber and scalp. Experts use:

Magnifying cameras to analyze the state of the cuticle.
High-precision sensors to measure hydration, elasticity, and hair density.
Targeted questionnaires to study your habits and environment.

This in-depth hair analysis (or hair consultation) allows for the recommendation of not only ultra-personalized care but also the specific hairbrush that will make all the difference.

You now have the keys to analyze your hair, alone or with professional help. The next step? Concretely identifying your hair type to further refine your routine.

Hair types: how to recognize them?

Identifying your hair type is a bit like discovering its "identity card": every detail counts. Texture, thickness, movement, shine… everything can be read by sight and touch. A good hair diagnostic—whether done online or at home—allows you to understand how your hair behaves and which accessories will best showcase it.

This is the key to composing a personalized hair routine that respects your needs, while enjoying natural hair care and styling accessories that make your life easier.

Fine, thick, coily, curly, straight…

Every hair nature tells its own story. To compose a personalized routine and choose the right hairbrush, you must know how to read these signs:

Fine hair: Very small diameter, often imperceptible to the touch; it bends easily and sometimes looks flat. Its radiance is subtle; light passes through it easily.
Thick hair: Large diameter, a feeling of density; it offers more resistance to styling. Naturally, it provides generous volume and holds shapes well.
Curly hair: Visible curls starting from the root or mid-length, with a natural bounce and a tendency to shrink as it dries.
Coily hair: Very tight curls, in a spiral or "S/Z" shape. Voluminous with a dry texture, it requires reinforced hydration.
Straight hair: A smooth surface without waves from roots to ends. It reflects light very well, hence its silky appearance.

Porosity, density, and scalp

Hair porosity refers to the ability to absorb and retain moisture. Well-closed scales keep water and treatments in better, making the hair soft, supple, and easy to style. Conversely, higher porosity absorbs products quickly but loses moisture just as fast, requiring richer and more regular care. Knowing this parameter allows you to choose between light or nourishing textures to optimize every ritual.

As for hair density, it refers to the number of hairs present on the scalp. High density naturally offers volume and body, even when individual hairs are fine, while lower density often requires specific styling—blow-drying, texturizing products, adapted accessories—to maximize the visual effect and give an impression of mass.

Finally, the condition of the scalp is just as essential as that of the lengths. Dry, sensitive, balanced, or oily, it directly determines the vitality of the hair. A healthy scalp promotes regular growth, limits breakage, and supports the resistance of the fiber. When it is weakened, targeted treatments like serums or gentle shampoos rebalance its comfort and restore strength and radiance to the hair.

By knowing the shape, density, and condition of your scalp better, you can go further. Use the Bachca hair diagnostic tool to obtain a complete and personalized analysis.

Which brush to recommend for each profile?

Finding the right brush is like uncovering the secret that will reveal all the beauty of your hair. Depending on your hair type and the needs of your scalp, certain accessories become true allies.

Curly hair

Curly hair needs suppleness, hydration, and a respectful touch. Its spiral structure makes the fiber more fragile, as moisture has difficulty circulating along the curl. A detangling and volume brush or a wide-tooth comb preserves the natural shape without breaking the bounce or causing frizz. It helps keep curls supple, defined, and shiny from morning to night.

Flat hair

Flat hair, often fine, demands volume and lightness. A well-designed volume brush gently lifts the roots, airs out the fiber, and creates an immediate impression of density. In a few strokes, the lengths regain thickness, natural movement, and an airy effect that dynamizes the whole hairstyle.

Sensitive scalp

A sensitive scalp calls for respect and special attention. Tightness or irritation can be soothed thanks to a soft brush equipped with flexible pins, which gently stimulate circulation without aggression. You thus transform styling into a true moment of comfort, where every stroke of the brush becomes a relaxing and beneficial massage.
