Hair loss affects both men and women – often in different ways but with equal emotional weight. For some, it’s a sudden shift. For others, a slow, unsettling progression: more scalp showing in the mirror, a receding hairline, patches thinning without warning. So what actually causes it? Hair loss rarely has a single trigger. It can be driven by genetics, stress, hormonal fluctuations, nutrient deficiencies, inflammation, or underlying health conditions. 

At Takroni Clinic, we take a different approach. Using advanced diagnostic tools like the Tricotest, and regenerative treatments including PRP, Exosomes and Polynucleotides, we identify the root cause and build a personalised plan to support lasting regrowth. If you’re looking for clarity – and real answers – you’re in the right place. Using a genetic test called TrichoTest we can personalise your treatments by analysing your unique genetic variations and lifestyle factors. Our regenerative treatments include PRP, exosomes and polynucleotides to help support a healthy scalp, reduced hair shedding and improved hair growth.

What are the main causes of hair loss?

Hair loss is not one condition – it’s a symptom. A response to internal imbalance. To treat it, we must understand what’s driving it.

The most common causes include:

• Androgenetic alopecia: Also known as male or female pattern baldness. This genetic form of hair thinning affects both sexes, often progressing gradually over years.
• Telogen effluvium: A reactive hair loss triggered by physical or emotional stress, surgery, illness, or hormonal change.
• Autoimmune hair loss: Conditions such as alopecia areata, where the immune system disrupts the normal hair cycle.
• Nutritional deficiencies: Low iron, B12, zinc, or vitamin D can all impact the hair follicle’s ability to grow strong strands.
• Thyroid imbalances, inflammation, and chronic illness: These can all contribute to excessive shedding or poor regrowth.
• Effects of hair styling and heat 
• Effects of the use of certain medications

At Takroni Clinic, we start with the Tricotest — a non-invasive, in-depth diagnostic assessment designed to give us a clear picture of your scalp and hair health. Rather than guessing, we gather clinical data on hair density, follicular activity, inflammation markers, and potential hormonal imbalances.

While it may not pinpoint the exact cause of your hair loss, the Tricotest helps us identify patterns and assess which treatment options are most likely to succeed — from PRP and exosomes to tailored supplementation plans. It’s a smarter, medically guided way to approach hair restoration.

How do I regrow my hair?

Hair regrowth requires precision, patience, and the right biological conditions. That’s why we begin with the Tricotest— a state-of-the-art DNA analysis that allows us to personalise your treatment plan from the inside out.

Using a simple cheek swab and lifestyle questionnaire, the test analyses genetic markers that influence hair health. It reveals which treatments are likely to be more effective for you, which active ingredients your body may respond best to, and even the ideal delivery formats — whether topical, oral, or injectable.

Armed with this insight, we can recommend regenerative therapies that directly stimulate the follicles and support longer-term regrowth, all tailored to your unique biology.

• PRP (Platelet-Rich Plasma): Using your body’s own growth factors to reactivate dormant follicles
• Exosomes: Next-generation cellular messengers that support hair regeneration can be microneedled into the scalp which further helps stimulate follicles.
• Polynucleotides: DNA-based molecules that repair and revive the scalp environment.

Each works differently, and they’re often used in combination. There’s no ‘one-size-fits-all’ but we can work together using clinically proven treatments to help improve your scalp health, reduce the rate of hair shedding and hopefully stimulate new hair growth.

Does PRP actually regrow hair?

Yes – particularly when the follicles are still alive but underperforming.

PRP (Platelet-Rich Plasma) involves drawing a small sample of your blood, spinning it to isolate the platelet-rich component, and then injecting this concentrate directly into the scalp. Platelets contain key growth factors that increase blood flow, encourage collagen production, and stimulate follicular activity.

At Takroni Clinic, a course of PRP is administered at monthly intervals for best results.Patients may begin to see results within 3–6 months, including reduced shedding, stronger strands, and new growth in sparse areas.

PRP is particularly effective for:

• Early-stage genetic hair loss
• Stress-related or postpartum hair shedding
• Hair thinning in perimenopausal or menopausal women
• Men with receding hairlines or crown thinning

Is PRP treatment good for hair?

PRP is considered one of the most effective non-surgical hair restoration options available today. Because it uses your own blood, the risk of reaction is minimal, and the process is relatively quick – usually under an hour per session.

Benefits include:

• Thicker, stronger individual hairs
• Reduced shedding
• Healthier scalp circulation
• Improved follicle longevity

At Takroni Clinic, we typically recommend a course of three sessions spaced four weeks apart, followed by maintenance every 6–12 months, depending on your response and ongoing hair goals.

How long does PRP last for hair?

PRP results are not permanent, but they are lasting – particularly when supported with the right home care and nutrition.

On average, results from PRP last 9 to 12 months, with some patients maintaining improvements even longer. Regular top-ups help extend the benefits and keep hair follicles functioning optimally.

Do exosomes work for hair growth?

Exosomes are one of the most exciting frontiers in regenerative medicine- and hair growth is no exception.

These tiny vesicles act as molecular couriers, delivering genetic material and growth signals between cells. When applied to the scalp, they tell dormant or damaged hair follicles to re-enter the growth phase.

Unlike PRP, which depends on your own biology, exosomes offer consistency and higher concentration of regenerative signals, making them ideal for improving hair growth and reducing hair shedding with clinically proven results. 

At Takroni Clinic, we use only lab-purified, ethically sourced exosomes, derived from colostrum or rose stem cells. These high-quality formulations are selected for their regenerative potential, safety profile, and growing support in clinical literature.

By using these specific sources, we aim to enhance scalp health, support follicular repair, and stimulate stronger, more resilient hair growth — all underpinned by careful patient selection and a results-led protocol.

Which is better, exosomes or PRP?

They’re both powerful, but they work slightly differently.

• PRP is autologous (from your own blood), excellent for early hair loss, and promotes natural follicular repair.
• Exosomes are lab-derived and act more like potent signals for cellular regeneration, ideal for more stubborn or advanced cases.

In some cases, we recommend combining the two – first reconditioning the scalp with PRP, then reinforcing results with exosome therapy.

For those needing additional support, we may also introduce Polynucleotides – injectable treatments that support DNA repair, reduce inflammation, and prime the scalp for better regrowth outcomes.

The Tricotest: Getting to the root of it

Before any treatment, we recommend the Tricotest – a cornerstone of our hair restoration protocol. The analysis of genetic factors and your medical history allows us to personalise your hair loss treatment to the highest level. 

This in-depth diagnostic maps out:

• Scalp health and hydration
• Follicular density and distribution
• Growth phase ratios
• Inflammatory markers
• Hormonal and metabolic indicators

It reduces the guesswork when it comes to deciding on treatment options and allows us to offer our patients the most personalised approach available in hair restoration today Ready to take the next step?

Hair loss may feel overwhelming, but with the right diagnostics and a treatment plan that’s rooted in regenerative science, there is are solutions that can be effective for you, whether you’re experiencing early thinning or more significant hair loss, our team at Takroni Clinic is here to help.
