Choosing the best shampoo shouldn't be so challenging, but with so many options promising stronger, shinier, smoother hair, it’s easy to end up with a bottle that isn’t doing your hair any favours.
The secret? It starts with understanding your hair type.
Your hair type influences everything from how often you wash to which shampoo will deliver the best results. Fine, flat hair has very different needs to colour-treated hair. Dry, damaged strands need something different again to curls, coils and waves.
Using the wrong shampoo can leave hair feeling weighed down, stripped, frizzy or lacking volume before you’ve even reached the styling stage. The right shampoo, on the other hand, helps support healthier-looking hair from the very first wash.
Before you add another bottle to your shower shelf, take a few minutes to understand your hair’s structure, texture, scalp type and overall condition. A simple hair strand test can help you check whether your hair is fine, medium or thick, while an elasticity test can show if your strands are strong and hydrated or in need of repair.
Once you know what you’re working with, finding your perfect shampoo match becomes a whole lot easier.
How To Identify Your Hair Type
Before choosing a shampoo, it’s worth getting to know how your hair naturally behaves. Understanding your hair structure, texture, scalp type and elasticity will help you choose products that work with your hair, not against it.
Hair Structure
Hair structure refers to the thickness of individual strands and the density of your hair overall.
- Fine hair: Thin, delicate strands. Hair can appear limp and is prone to breakage. Avoid heavy shampoos that weigh it down.
- Medium hair: Balanced strands that can hold styles and products well. Most shampoos suit this type.
- Thick hair: Coarse or dense strands that may need hydrating or smoothing formulas to manage volume and frizz.
How to test: Roll a single strand between your fingers. Fine hair feels almost invisible, medium hair is easy to feel, and thick hair feels firm and coarse.
Hair Texture
Texture is about how your hair naturally falls: Straight: Flat from root to tip; may need volumising products.
- Wavy: Loose S-shaped bends, benefits from hydration and frizz control.
- Curly: Defined spirals, needs moisture to hold shape and prevent frizz.
- Coily / Kinky: Tight, springy curls prone to dryness and shrinkage, requires gentle cleansing and intense hydration.
How to test: Observe your hair after washing and air-drying, without styling products. Notice the natural pattern it falls into: straight, slightly bent, spiral, or tight coil?
Scalp Type
Your scalp affects how your hair behaves daily, from oil production to sensitivity.
- Oily: Hair becomes greasy quickly. Look for balancing shampoos.
- Dry: Scalp may feel tight, itchy, or flaky. Hydrating shampoos restore moisture.
- Sensitive / Reactive: Prone to redness or irritation. Gentle, barrier-supporting formulas work best.
- Normal: Balanced; most shampoos are suitable.
How to test: Examine your scalp before washing. Press fingers to your scalp to check for oiliness, look for flaking or irritation, and note how quickly hair becomes greasy after washing.
Hair Strand Test
Once you know your hair type, you can do a simple hair strand test to learn more about your hair’s health and needs.
- Wash and air-dry your hair so it’s clean and product-free.
- Take a single strand from the middle of your head.
- Roll it between your fingers to check thickness (fine, medium, thick).
- Observe its natural pattern for texture (straight, wavy, curly, coily).
- Examine the ends for split ends or dryness.
Hair Elasticity Test
Hold the strand at both ends. Gently stretch it.
Try and yest a few strands from different areas of your head for a full picture. Hair can vary depending on exposure to heat, chemicals, or natural oils.
Results:
- Healthy hair: Stretches slightly and returns to its original length. Strong, hydrated, and resilient.
- Low elasticity: Snaps easily or stretches unevenly. Hair is fragile and may need protein or strengthening treatments.
Choosing the Best Shampoo For You
Now that you’ve identified your hair type, structure, texture, and scalp needs, it’s easier to select a shampoo that works for you. Here’s a guide for common scenarios:
Dry or Thirsty Hair
If your hair feels rough, tangles easily or struggles to hold moisture between washes, hydration should be your starting point.
Look for: Moisture-rich shampoos that gently cleanse while helping replenish hydration and improve softness.
Signs you need it:
- My hair feels dry by the end of the day.
- I struggle with frizz and flyaways.
- My hair never feels soft, even after conditioning.
NAK Recommendation: Hydrate Shampoo helps replenish moisture while improving softness, smoothness and shine. Ideal for dry or dehydrated hair needing a hydration boost.
Colour-Treated Hair
Fresh colour deserves the right care to help maintain vibrancy, shine and softness between salon visits.
Look for: Nourishing shampoos that help support colour longevity while keeping hair hydrated and healthy-looking.
Signs you need it:
- My colour fades quickly between appointments.
- My hair feels dry after colouring.
- My colour lacks shine and vibrancy.
NAK Recommendation: Nourish Shampoo helps replenish moisture and support colour vitality while keeping hair soft, smooth and healthy-looking. Ideal for maintaining shine and extending the life of your colour.
Fine, Flat or Limp Hair
If your hair lacks body, falls flat quickly or feels weighed down after washing, volume-focused formulas can help create lift without residue.
Look for: Lightweight shampoos that add fullness and movement while keeping hair feeling fresh.
Signs you need it:
- My roots fall flat by midday.
- My hair struggles to hold volume.
- Heavy products make my hair greasy.
NAK Recommendation: Volume Shampoo helps create fullness and body while maintaining softness and shine. Its lightweight formula leaves hair feeling refreshed, bouncy and lifted from root to tip.
Damaged or Fragile Hair
Heat styling, chemical services and everyday wear can leave hair feeling weak, brittle and more prone to breakage.
Look for: Protein-rich shampoos that help reinforce the hair structure while improving strength and resilience.
Signs you need it:
- My hair feels weak or overprocessed.
- I notice more breakage when brushing or styling.
- My hair feels stretchy when wet.
NAK Recommendation: Structure Complex Protein Shampoo helps strengthen and reinforce damaged strands with protein-rich care, improving resilience, manageability and overall hair condition.
Curls, Coils or Waves
Curly hair often needs a delicate balance of cleansing and moisture to maintain definition without feeling stripped.
Look for: Gentle, moisturising shampoos that cleanse without disrupting your natural curl pattern.
Signs you need it:
- My curls look better days after washing.
- My hair feels dry after shampooing.
- My curl definition disappears quickly.
NAK Recommendation: Curl Shampoo gently cleanses while helping support curl definition, softness and bounce for healthier-looking curls, coils and waves.
Blonde or Tone-Sensitive Hair
Blonde, highlighted and grey hair can develop unwanted warmth and brassiness between salon visits.
Look for: Toning shampoos that help neutralise unwanted yellow tones while maintaining hair condition.
Signs you need it:
- My blonde is looking yellow or brassy.
- My highlights have lost their brightness.
- My cool tones fade quickly.
NAK Recommendation: Blonde Plus Shampoo helps maintain brighter, cooler blonde tones while keeping hair soft and manageable.
Common Mistakes That Affect Results
Even the right shampoo can fail if your routine isn’t correct:
- Washing too often or not enough: Most hair types do best every 2–3 days.
- Using too much product: A 10-cent piece-sized amount is enough.
- Skipping scalp massage: Boosts circulation and helps shampoo work effectively.
- Rinsing too quickly: Residue can weigh hair down.
