Struggling with thinning hair and wondering how to increase hair density? In this guide, we break down the best solutions by Dr. Serkan Aygin, recipient of the Best Hair Doctor in Europe award (Paris, 2019).
Whether you’re considering natural remedies, medication, PRP, laser therapy, or hair transplants, discover the most effective methods to boost your hair density today.
What is Hair Density?
Hair density refers to the number of hair strands per square inch (or square centimeter) of the scalp. It is a critical factor that determines how full or thick your hair appears. Hair density is often confused with hair thickness, but these are two distinct characteristics:
- Hair density: Measures the number of hair strands growing per area of the scalp.
- Hair thickness: Refers to the diameter of each hair strand, meaning how fine or coarse a single hair strand is.
For example, someone may have a high hair density with fine hair strands, resulting in a voluminous but soft texture. Conversely, another person may have a lower hair density but thick strands, giving a fuller appearance with fewer hair follicles per square inch.
What is High Density Hair?
High-density hair means a person has a large number of hair strands growing per square inch. Generally, a density of over 2,200 hairs per square inch (85–90 follicles per cm²) is considered high. Individuals with high hair density have a fuller, voluminous look even when their hair is not styled.
Characteristics of high-density hair:
- More than 150,000 hair strands on the scalp (average for high-density individuals)
- Requires more product to style and maintain
- Holds volume well without excessive teasing or styling
What is Low Density Hair?
Low-density hair means fewer hair strands growing per square inch. Typically, a density of less than 1,500 hairs per square inch (50–60 follicles per cm²) is categorized as low. People with low-density hair may notice more scalp visibility, especially when their hair is parted or wet.
Characteristics of low-density hair:
- Less than 100,000 hairs on the scalp
- May appear thin or sparse, especially when hair is straightened
- Benefits from volumizing products and hairstyles that add fullness
Hair Density Chart
To determine hair density, experts use a hair density chart, which helps classify hair types based on the number of follicles per square inch. Below is a general breakdown:
Hair Density Level | Follicles per cm² | Hairs per square inch | Scalp Visibility |
Low Density | 50–60 | <1,500 | High |
Medium Density | 60–85 | 1,500–2,200 | Moderate |
High Density | 85–90+ | >2,200 | Low |
To measure your own hair density, you can try the hair density scanner online tool, contact us for a free online consultation, or use a simple parting method:
- Part your hair in different sections.
- Observe how much scalp is visible.
- Compare with the density chart to estimate your category.
Understanding hair density is essential for choosing the right hair care products, styling techniques, and treatments to maintain or improve the appearance of your hair.
What Causes Low Density Hair?
Several factors can contribute to low hair density. A precise analysis requires a consultation with a professional dermatologist or trichologist, but you might want to consider the following as a brief guide:
- Genetics: A primary factor determining hair density; some people naturally have fewer hair follicles.
- Aging: Hair follicles shrink and produce thinner hair over time, leading to reduced density.
- Hormonal Imbalances: Conditions like androgenetic alopecia, DHT imbalances or thyroid disorders can affect hair growth.
- Poor Nutrition: Deficiencies in iron, biotin, protein, and essential vitamins can weaken hair.
- Stress & Lifestyle: Chronic stress, smoking, and poor sleep can impact hair follicle health.
- Medical Conditions & Medications: Autoimmune diseases, chemotherapy, and certain medications can cause hair thinning.
- Scalp Health Issues: Conditions like dandruff, seborrheic dermatitis, or clogged follicles can affect hair density.
Dr. Serkan Aygin’s 7 Most Effective Treatments on How to Improve Hair Density
If you’re wondering how to increase hair density, there are multiple solutions ranging from advanced medical treatments to natural remedies.
Bear in mind, below are the most effective methods as practiced by Dr. Serkan Aygin:
1. Stem Cell Therapy
- Uses stem cells to regenerate hair follicles and stimulate new hair growth.
- Can increase hair density by promoting follicle rejuvenation.
- Still in research phases but shows promising results for thicker, fuller hair.
2. PRP (Platelet-Rich Plasma) Therapy
- PRP involves drawing a patient’s own blood, processing it to extract growth factors, and injecting it into the scalp.
- Boosts hair follicle activity, improving hair thickness and density.
- Works best for early-stage hair thinning rather than complete baldness.
3. Laser Therapy
- Uses low-level laser light to stimulate cell activity in hair follicles.
- Red light can increase blood circulation, leading to healthier and denser hair growth.
- Often used in combination with PRP or topical treatments like Minoxidil.
4. Dermaroller
- A microneedling tool that creates tiny punctures in the scalp to boost collagen production and stimulate hair follicles.
- Increases the absorption of topical hair growth serums.
- Works well with Minoxidil or natural oils like castor oil.
5. Hair Transplant
For individuals with severe low hair density, a hair transplant offers permanent results by redistributing healthy hair follicles. Some of the best techniques for density improvement include:
- FUE Sapphire: Uses a sapphire blade for precision and higher graft survival rates, leading to a more natural and denser result.
- DHI (Direct Hair Implantation): Transplants hair follicles directly without creating incisions, offering a fuller appearance with higher density.
- Long DHI: Dr. Serkan Aygin’s trademark fo reven better, denser results.
- Hair Transplant for Women: Unlike male transplants, density-focused techniques help preserve natural hairline aesthetics in women.
- Stem Cell Hair Transplant: Combine stem cell therapy with hair transplantation for the best possible results.

6. Medication (Minoxidil & Rogaine)
- Minoxidil (Rogaine) is FDA-approved and stimulates hair regrowth by increasing blood flow to the scalp.
- Works well for mild to moderate hair thinning, but results take 3-6 months to appear.
- Requires consistent use—stopping can lead to hair loss recurrence.
7. Natural Remedies
If you prefer non-invasive solutions, natural remedies can help improve hair density by nourishing the scalp and strengthening hair follicles:
- Hair Density Serums – Contain peptides, caffeine, biotin, and botanical extracts to boost thicker hair growth.
- Aloe Vera – Soothes the scalp, reduces inflammation, and enhances follicle health.
- Diet & Nutrition – Consuming foods rich in olive oil, omega-3 fatty acids, eggs, nuts, and leafy greens can improve hair growth and density.
