Why do a hair diagnosis?

Dry, brittle, flat, or tangled hair… Faced with these recurring problems, it's often tempting to use many products without really addressing the cause. However, the solution begins with a simple and often overlooked step: understanding the true nature of your hair. This is exactly what ahair diagnosisallows you to do. A real hair health check-up, it analyzes texture, porosity, scalp condition, and the specific needs of each hair type to guide you toward the right accessories and practices. At Bachca, we've developed a free and accessible online hair diagnosis to help everyone find the brush best suited to their hair. Here's everything you need to know about hair diagnosis: what it is, how to do it, and why it truly changes the way you care for your hair.

What is a hair diagnosis and why is it essential?

Hair diagnosis is a comprehensive evaluation of the condition of the hair andscalp. It takes into account several criteria: hair texture (fine, thick, curly, straight), porosity level, degree of fragility, and specific daily problems encountered: lack of volume, frizz, breakage, dryness, sensitive scalp.

Why most hair routines are ineffective without diagnosis

Using an unsuitable brushfor your hair type is like applying a cream for oily skin to dry skin: at best ineffective, at worst counterproductive. A brush that is too dense on fine hair weakens it. Bristles that are too rigid on a sensitive scalp irritate it. Hair diagnosis helps to avoid these common errors and to invest in truly suitable accessories.

A simple step for lasting results

A well-performed hair diagnosis only takes a few minutes, but its benefits are felt in the long term: less breakage, easier detangling, a better stimulated scalpand visibly healthier and shinier hair.

How to perform a self-diagnosis of your hair at home?

Before consulting a professional or using an online tool, you can start with a simple at-home test: the porosity test. This test assesses the hair's ability to absorb and retain moisture, a key indicator for choosing the right hair care products and accessories.

The water glass test: instructions for use

Take a few clean hairs from your brush and gently place them on the surface of a glass of water. Observe their behavior after a few minutes.

If the hairs float on the surface, their porosity is low: they absorb little moisture and tend to be smooth and resistant, but may lack deep hydration.

If the hairs sink slowly, their porosity is medium: this is the most common profile, a sign of balanced hair.

If the hairs sink quickly to the bottom, their porosity is high: the hair absorbs a lot but retains moisture poorly. It is often dry, porous, and prone to frizz.

Limitations of the home test

The porosity test provides a useful indication, but it is insufficient for a complete hair diagnosis. It does not provide information on hair texture, thickness, scalp condition, or the most suitable accessories. Therefore, it is recommended to supplement this initial assessment with a more comprehensive method.

The three ways to perform a comprehensive hair diagnosis

There are several approaches to conducting a thorough hair diagnosis, each with its advantages depending on the time available and specific needs.

Some hair salons offer hair assessments using professional tools: magnifying cameras, scalp analysis, evaluation of hair density and resistance. This is the most precise method, particularly recommended in cases of significant hair loss, persistent scalp problems, or severely damaged hair. However, it requires a visit to the salon and can sometimes incur a significant cost.

Many hair care brands offer online questionnaires to help identify hair type and needs. These tools are practical and accessible, but they primarily guide users towards cosmetic products (shampoos, masks, serums) and do not always take into account essential brushing accessories for a balanced hair care routine.

FAQ's

What is a hair diagnosis and what is its practical use?

A hair diagnosis is an evaluation of the condition of the hair and scalp that takes into account texture, porosity, thickness, and specific hair issues: dryness, breakage, lack of volume, frizz. It helps identify the hair's real needs to adapt one's routine: choice of products, washing frequency, styling techniques, and especially the selection of the right brushing accessories. Performing a hair diagnosis helps avoid using unsuitable tools that can weaken hair or irritate the scalp in the long term.

How can I tell if my hair has high or low porosity?

The simplest porosity test involves placing a few clean strands of hair in a glass of water and observing their behavior after a few minutes. Hair that floats has low porosity: it absorbs little moisture and remains smooth but may lack nourishment. Hair that sinks quickly has high porosity: it absorbs quickly but retains moisture poorly, making it dry and prone to frizz. Hair that remains suspended in the middle has normal porosity. This test provides a useful initial indication, but for a complete diagnosis tailored to accessories, the online Bachca questionnaire remains the fastest and most accurate method.
