Summary
Identifying the right care for your hair type is the foundation of an effective routine. Hair diagnosis, from texture to hydration needs, helps choose appropriate hair care products and establish a consistent daily routine.
How to identify your hair and scalp type
Implementing hair care without knowing your hair type is like walking blindfolded. The shape of the hair fiber, its porosity, and the condition of the scalp guide the choice of shampoo, product textures, and washing frequency. To build a suitable routine, you must first observe the hair's actual texture, then link this observation to its needs: hydration, nourishment, repair, or lightness.
In practical application, this can range from a gentle sulfate-free shampoo to masks with phytokeratin, aloe vera, or plant oils, depending on the hair's reaction and the behavior of the lengths.
The 4 hair types according to the André Walker classification
The André Walker classification divides different hair types into four families, further broken down into subcategories a, b, and c, where the curl pattern tightens as the letter progresses.
Type 1 corresponds to straight hair, often more reflective to light because sebum easily travels along the fiber. Type 2 forms S-shaped waves, which are more or less flexible depending on whether it's type 2a, 2b, or 2c. Type 3 forms true curls or spirals, with more bounce. Finally, Type 4 has very tight coils and significant shrinkage when exposed to humidity.
Porosity, thickness, and scalp type
A reliable hair diagnosis is based on three axes: porosity, thickness, and scalp. The water glass test can provide a simple indication: if the hair sinks quickly, the cuticles are often more open; if it floats, the penetration of active ingredients may be slower.
- Fine fiber: more fragile, dries quickly, and requires light care to preserve volume.
- Medium fiber: more balanced, it easily accepts different care textures, from fluid to rich.
- Thick fiber: more robust, it often requires more hydration and a more generous leave-in time to limit frizz.
The nature of the scalp is just as important. Normal, dry, oily, or combination, it influences washing frequency, shampoo choice, and the overall balance of the routine. These parameters evolve with seasons, diet, or hormonal changes: the difference plays out over time, hence the importance of regularly readjusting your routine according to the actual evolution of the hair fiber.
How to test your hair type at home
The most accurate reading is done on clean hair, without heavy styling products. Start with a gentle shampoo, then apply a little aloe vera to damp lengths, focusing on the lengths if the roots get oily quickly. Then, gently scrunch towards the scalp before letting it air dry or using a diffuser.
Once dry, the natural movement appears more clearly. Straight strands indicate type 1 straight hair; S-waves indicate type 2; defined spirals indicate type 3; and very tight coils with shrinkage indicate type 4.
This identification is not fixed. Hair can change with sun exposure, seawater, cold weather, certain treatments, or hormonal changes. Re-evaluating your hair type twice a year helps maintain a stable routine and care that is as close as possible to its real needs.
To combine shampoo, hydration, and targeted actions according to different hair types, this guide provides complementary benchmarks: natural hair care.
Daily care for straight and wavy hair
Straight and wavy hair share a common need: avoiding overload. However, the routine is not built the same way depending on the hair type, because hydration, textures, and application gestures do not meet the same expectations.
Care for fine or thick straight hair
Care for straight hair requires lightweight formulas. For normal to fine hair, a silicone- and sulfate-free shampoo helps cleanse without weighing down the fiber, while limiting excess sebum at the roots. Conversely, thick straight hair accepts slightly more flexible textures to tame unruly strands.
- Sulfate-free shampoo: gently cleanses without stripping the hydrolipidic film or stimulating sebum overproduction.
- Light conditioner: provides necessary hydration without weighing down, to be applied primarily to lengths and ends.
- Lightweight masks: a light formula every 7 to 10 days is often sufficient for normal hair, whereas overly rich products can flatten the hair.
- Cool air drying: helps maintain volume without weakening the fiber or accentuating frizz.
For oily roots, spacing out washes remains relevant. Additionally, a light dry shampoo absorbs sebum between washes without drying out the lengths.
Routine adapted to wavy hair type 2
Type 2 encompasses three profiles: 2a for soft waves, 2b for more visible definition, 2c for a denser texture often prone to frizz. To delve deeper into the needs of curly hair, this content dedicated to curly hair helps precisely identify the fiber's profile.
For wavy hair, the scrunching technique involves gently pressing damp lengths upwards with a light gel to encourage the shape without stiffening it. The next day, a simple mist of water is often enough to reactivate the movement. For the driest wavy hair, especially 2c, enhanced hydration with aloe vera usefully complements the routine, right from the first applications.
Care for curly and coily hair types 3 and 4
The spiral or zigzag shape of curly, coily, and afro hair slows down the natural distribution of sebum between the roots and the lengths. The fiber therefore remains more exposed to dryness, making precise targeting of care essential. The tighter the hair type, the more central nutrition becomes in the routine.
Hydration and nutrition for curls and coils
Elyara formulations for curly and coily hair are based on simple, but well-chosen active ingredients. Aloe vera helps soothe and limit frizz, shea butter provides deep nourishment, glycerin supports hydration, while phytokeratin helps restructure weakened hair. In practical application, a mask combining phytokeratin, aloe vera, and castor oil provides a complete solution for types 3 and 4.
Provitamin B5 coats the fiber and visibly thickens the hair. This support extends the effect of the mask between treatments. For 3c to 4c textures, often more prone to breakage, alternating between oil baths and nourishing masks each week helps maintain hydration without weighing down the hair.
Essential gestures to preserve curls daily
Each textured hair type reacts strongly to the regularity of actions. Afro hair has a fiber more vulnerable to dehydration and breakage, which makes the routine more important than one-off treatments.
- Wet detangling: on wet hair, with a conditioner, detangling is done from ends to roots using a wide-tooth comb.
- Silk pillowcase: a silk or satin pillowcase limits nocturnal friction and helps the hair retain its hydration.
- Gentle hairstyles: overly tight ties weaken tension areas and promote breakage, especially at the hairline.
- Limited heat: a diffuser on low heat is preferable to a flat iron or overly hot hairdryer, especially for the ends.
For types 3 and 4, washing often finds its balance between once and twice a week. A sulfate-free shampoo followed by a nourishing conditioner forms a solid base for a lasting routine. This rhythm respects the hydrolipidic film and prevents drying out the lengths.
Care for afro hair can also include a light leave-in treatment between washes. A few drops of light oil on the ends are often enough to prolong suppleness and limit breakage in the driest areas.
Oil baths adapted to types 3c to 4c
The oil bath remains a very relevant deep treatment for curly, coily, afro hair, and more generally, thick hair prone to dryness. Coconut oil intensely nourishes, while castor oil and jojoba oil help strengthen the fiber.
For a type 4, leaving it on under a heated cap overnight promotes penetration. A warm towel placed over it can further improve absorption. Rinsing is done with lukewarm then cool water to smooth the cuticles.
In practice, an oil bath every two weeks, combined with a weekly mask, supports continuous repair. This rhythm is well suited to a routine focused on hydration, maintaining length, and preventing breakage, especially for the driest textures.
Hair care frequency based on your profile
The frequency of care is as important as its formulation. If too infrequent, the active ingredients don't sufficiently compensate for established dryness. If too close together, they saturate the fiber, weigh down the hair, and can sometimes imbalance the scalp. The difference plays out over time.
Frequency and leave-in time for hair masks
To determine the correct frequency for hair masks, the starting point remains the hair type and the actual needs of the hair fiber. Dry or very sensitized hair, especially some colored hair after bleaching, requires up to two applications per week. Conversely, normal hair is satisfied with a more spaced-out rhythm, while fine and oily hair benefits from a maximum of one weekly application.
The leave-in time follows the same logic. A mask should be applied to slightly damp, towel-dried, and detangled hair, preferably to the lengths and ends. A lukewarm, then cooler, rinse helps smooth the cuticle once the mask is rinsed out. Details of useful adjustments in case of excess or lack are accessible via the link below: hair mask frequency.
| Hair profile | Mask frequency | Leave-in time |
| Very dry / very damaged hair | Twice a week | 15 to 30 min (heated cap) |
| Dry / moderately damaged hair | 1 to 2 times a week | 15 to 20 min |
| Normal hair | Every 7 to 10 days | 5 to 10 min |
| Fine / oily hair | Maximum once a week | 5 to 10 min |
An interval of 5 to 7 days between two applications is suitable for most routines. Beyond three masks per week, the risk increases: dull lengths, heavy feel, roots that get oily faster. These signals indicate that applications should be lightened or spaced out.
Adjusting care after coloring or chemical treatment
After coloring or a chemical treatment, the routine must evolve for a few weeks. A first repairing mask within 48 hours helps tighten the cuticles and limit material loss. Phytokeratin finds its full place here: the treatment acts where the fiber has been weakened.
- After standard coloring: 1 to 2 masks per week to preserve color, support hydration, and limit the appearance of brittle hair.
- After bleaching or lightening: 2 to 3 applications per week for 4 to 6 weeks to support repair.
- After Brazilian straightening or relaxer: 2 masks per week, for example, Monday and Thursday, for 4 to 6 weeks.
- Sign of under-use: rough ends after 3 weeks of routine indicate a need to switch to 2 weekly applications with a phytokeratin-enriched formula.
In addition, a light leave-in treatment extends protection between washes. Weekly observation of shine, softness, and suppleness allows for more accurate adjustment of the rhythm, right from the first applications.
Complete routine for a balanced scalp and lengths
Keeping the same day for the mask helps establish a stable routine, especially when needs vary by season or hair condition. A monthly oil bath, or bi-monthly for severely dry hair, usefully complements hair care without overloading the lengths.
Balance comes from the whole. Combining shampoo, mask, oil bath, and leave-in treatment in a coherent order helps meet the actual needs of the hair fiber, whatever the profile.
Frequently asked questions
How do I know my hair type?
The most reliable assessment is done on clean hair, after a gentle sulfate-free shampoo and without styling products. Then, let the hair air dry or use a diffuser, and observe its natural shape: straight strands correspond to type 1 straight hair, S-waves to type 2, spirals to type 3, and very tight coils to type 4, common in afro hair.
In addition, two indicators refine the diagnosis. The water glass test helps evaluate porosity, while comparing it to a sewing thread helps estimate if the hair fiber is fine, medium, or thick. This cross-referencing provides a more accurate reading and guides you towards the most targeted care according to actual needs.
What are the different types of hair care products?
Hair care products are categorized by their function in a routine. Shampoo cleanses the scalp and prepares the hair fiber before the treatment steps. Then, conditioner and mask provide hydration and nourishment, with textures adjusted according to hair type.
Before washing, an oil bath made with coconut, castor, or jojoba oil deeply nourishes the hair fiber. Then, leave-in treatments, such as serum, light oil, or mist, extend protection between washes: in practical application, each formula addresses a specific need, whether it's repairing, defining, volumizing, or maintaining comfort, depending on the hair type.
What hair type is the most difficult to maintain?
Type 4 often requires the most attention, especially for 4c subtype Afro hair. The very tight curl pattern of the fiber hinders the natural distribution of sebum, which increases susceptibility to dryness. Unlike straighter hair, breakage can occur more quickly if the routine lacks consistency.
For this hair type, balance lies in consistency: weekly masks, regular oil baths, detangling on damp hair, and nightly silk protection. Treatments chosen according to the need for suppleness, hydration, and strength help preserve the hair fiber in the long term.
