Understanding your low porosity hair care is crucial for developing an effective hair care routine that truly works. Hair porosity determines how well your hair absorbs and retains moisture, influencing everything from product selection to styling techniques. At İstanbul Care Clinic, our experienced intermediary organization helps clients understand their unique hair characteristics to achieve optimal hair health and appearance.
Low porosity hair presents unique challenges and benefits that require specialized care approaches. With the right knowledge and products, individuals with low porosity hair can achieve healthy, beautiful results while avoiding common pitfalls that lead to product buildup and styling difficulties.
What is low porosity hair?
Low porosity hair is characterized by tightly closed cuticles that resist moisture absorption. The hair cuticles lie flat against the hair shaft, creating a protective barrier that makes it difficult for water, oils, and other products to penetrate the hair strand.
Key characteristics of low porosity hair:
- Cuticles are tightly closed and flat
- Moisture absorption is slow and difficult
- Hair tends to repel water initially
- Products often sit on the hair surface
- Once moisturized, hair retains moisture well
- Less susceptible to damage from environmental factors
This hair type is often genetic but can also result from minimal chemical processing or damage. The tight cuticle structure provides natural protection but requires specific care strategies to maintain optimal moisture levels.
| Hair Porosity Type | Cuticle Position | Moisture Absorption | Product Penetration |
|---|---|---|---|
| Low Porosity | Tightly closed | Slow / Difficult | Poor |
| Medium Porosity | Slightly raised | Moderate | Good |
| High Porosity | Very open | Rapid | Excellent |
What is Medium porosity hair?
Medium porosity hair represents the ideal balance between moisture absorption and retention. The cuticles are slightly raised, allowing for optimal product penetration while maintaining good moisture retention capabilities.
Medium porosity characteristics:
- Balanced cuticle structure
- Moderate moisture absorption rate
- Good product penetration
- Effective moisture retention
- Responds well to most hair products
- Maintains color and chemical treatments well
Benefits of medium porosity:
- Easiest hair type to manage
- Accepts and retains treatments effectively
- Requires minimal specialized care
- Responds to various styling techniques
- Natural resilience to damage
Most people with medium porosity hair can use standard hair care products without significant issues, making it the most manageable hair porosity type.
What is High porosity hair?
High porosity hair features raised or damaged cuticles that allow moisture and products to enter easily but struggle to retain them. This condition often results from chemical processing, heat damage, or environmental stress.
High porosity characteristics:
- Cuticles are raised or damaged
- Rapid moisture absorption
- Poor moisture retention
- Quick product absorption
- Prone to frizz and tangling
- Requires frequent moisturizing
Common causes:
- Chemical processing (coloring, perming, relaxing)

- Natural aging of hair
High porosity hair requires intensive moisturizing treatments and protective styling to maintain health and manageability.
How to know if you have low porosity hair
Determining your hair porosity is essential for selecting appropriate products and treatments. Several simple tests can help identify low porosity hair characteristics.
There are two easy hair porosity tests you can try at home:
The Float Test:
- Take a clean strand of hair from your brush
- Fill a clear glass with room temperature water
- Place the hair strand on the water surface
- Wait 2-4 minutes and observe
Results interpretation:
- Hair floats: Low porosity
- Hair sinks slowly: Medium porosity
- Hair sinks immediately: High porosity
The Water Drop Test or Spray Test:
- Spray or drop water onto clean, dry hair
- Observe how quickly water is absorbed
- Note the water’s behavior on hair surface
The spray test provides immediate visual feedback about your hair’s porosity level and helps confirm results from other testing methods.
Spray test procedure:
- Section clean, dry hair

Frequently Asked Questions
Low porosity hair has tightly closed cuticles that resist moisture absorption. Products tend to sit on the surface, and hair takes longer to get wet but retains moisture well once hydrated.
Try the float test: place a clean hair strand in water. If it floats, you likely have low porosity hair. You can also spray water on your hair if it beads up, that indicates low porosity.
Low porosity hair isn’t bad it’s naturally protective and retains moisture well once hydrated. It just requires specific care techniques like using lightweight products and heat for deep conditioning.
Use lightweight, water-based products with humectants like glycerin. Avoid heavy oils and butters. Look for penetrating oils like argan or grapeseed oil and sulfate free, clarifying shampoos.
Apply products to damp hair, use heat during deep conditioning, choose humectant rich formulas, and layer lightweight moisturizers. Steam treatments are particularly effective for moisture penetration.
Lightweight oils with small molecules work best: grapeseed oil, argan oil, sweet almond oil, jojoba oil, and apricot kernel oil. Avoid heavy oils like castor or coconut oil.
Wash frequency depends on your scalp type and product usage. Generally, 2-3 times per week works well, with weekly clarifying to prevent buildup. Oily scalps may need more frequent washing.
Low porosity hair resists moisture but retains it well, while high porosity hair absorbs moisture quickly but loses it rapidly. Low porosity needs lightweight products and heat; high porosity needs heavy, protein rich products.
