A healthy scalp is the foundation of healthy hair. Whether you’re noticing increased shedding, finer strands, or overall lack of volume, it often starts with the condition of your scalp. Polynucleotides are transforming how we care for our hair by focusing on regeneration and healing — improving both scalp and strand from the inside out.

Results That Speak for Themselves
Polynucleotide scalp treatments are designed to boost circulation, calm irritation, and nourish your follicles from within. Over time, this helps improve texture, reduce shedding, and support long-term hair vitality.
This treatment supports both the scalp and delicate areas like the eyebrows — helping rehydrate the skin and encourage natural, healthy growth where thinning or dryness has occurred.
Your journey begins with a consultation. We’ll take the time to understand your scalp health, hair concerns, and goals. After a detailed assessment, your practitioner will create a personalised plan tailored to your needs.
During the session, Polynucleotides are gently injected into targeted areas of the scalp using fine needles. The treatment typically takes 20–30 minutes and is generally well-tolerated with minimal discomfort.
There’s no significant downtime. Some mild redness or sensitivity may occur, but this usually fades within 24–48 hours. Most people return to their regular routine straight after their appointment.
Women often see thinning around the parting or crown, often triggered by hormonal changes, stress, thyroid issues, or ageing. It doesn’t always show as bald patches — instead, hair becomes finer, flatter, and harder to style. Over time, the scalp may become more visible. Lifestyle, nutrition, and genetics all play a role in how hair behaves.
How Polynucleotides Help
By deeply hydrating the scalp, calming inflammation, and supporting follicle strength, polynucleotide treatments improve texture, add shine, and help maintain healthy volume — no hormones required.
Hair thinning in men can start early, sometimes even in their late teens or twenties. Commonly due to DHT sensitivity, stress, or genetics, this type of thinning usually begins around the temples or crown and can progress without intervention. Hair may become weaker, shed faster, or stop growing altogether.
How Polynucleotides Help
Treatments target follicle function, support blood flow, and calm the scalp environment — helping restore resilience and maintain thicker-looking hair. With regular care, men can slow the signs of thinning and encourage stronger regrowth.
Results That Speak for Themselves
Polynucleotides are naturally derived DNA fragments known for their ability to support cell regeneration and tissue repair. When applied to the scalp, they work by deeply hydrating the skin, improving microcirculation, calming inflammation, and promoting a balanced environment where hair can grow stronger and healthier.
• Rebalance the Scalp: Soothe inflammation, reduce sensitivity, and restore optimal conditions for hair growth.
• Hydrate and Nourish: Deeply moisturise dry or tight scalps for improved comfort and follicle function.
• Stimulate Regeneration: Encourage healthy cell turnover and repair scalp tissue to support thicker, fuller-looking hair.
• Boost Circulation: Improve oxygen and nutrient delivery to the follicles.
Polynucleotide treatments are an excellent solution for women experiencing hormonal or age-related hair thinning. They improve scalp health, reduce inflammation, and support long-term follicle strength without hormones or surgery. Sisu Clinic offers personalised polynucleotide protocols designed to treat thinning at the part line, crown, or diffuse shedding with minimal downtime.
Yes. Polynucleotide therapy is ideal for maintaining a healthy scalp — even before hair loss begins. It works by hydrating the skin, reducing inflammation, and supporting collagen production, helping to create the perfect environment for strong, resilient hair.
Absolutely. Polynucleotide injections help stimulate dormant follicles and improve the health of thinning areas like the temples or crown. It’s ideal for men noticing early signs of recession or slow regrowth.
Polynucleotide scalp treatments offer a natural alternative to chemical-based products. They restore hydration, support cellular repair, and improve the condition of the scalp — all of which can reduce shedding and support fuller regrowth.
Improving scalp health starts with hydration, reducing inflammation, and supporting cell renewal. Polynucleotide therapy works by delivering regenerative molecules into the scalp to restore balance, boost circulation, and improve overall skin condition. This provides a healthy foundation for stronger, fuller hair — naturally.
Eyebrow thinning can be caused by overplucking, hormones, or ageing. Polynucleotides can be safely used in the brow area to support healthier skin, reactivate follicles, and encourage natural regrowth over time.
A dry, irritated scalp is often a sign of dehydrated skin and poor barrier function, which can impact follicle health and hair quality.
Polynucleotide scalp therapy works by regenerating the skin from within:
• Deeply hydrates and soothes tight, flaky areas
• Supports collagen production for stronger scalp structure
• Improves circulation for healthier follicles
Ideal for: Dry, sensitive, or post-colour scalps, and anyone looking to restore comfort and balance.
Shedding can be triggered by stress, hormones, illness, or inflammation in the scalp. When the follicle weakens, strands fall out faster and regrow more slowly.
Polynucleotide injections help restore balance by:
• Calming inflammation that damages follicles
• Improving hydration and nutrient delivery
• Supporting stronger, longer hair growth phases
Ideal for: Men and women noticing seasonal shedding, post-COVID or postpartum shedding, or general hair density loss.
Topical products only treat the surface — the root cause is often poor scalp circulation or inflammation.
Polynucleotides go deeper:
• Rebuild the scalp’s cellular structure
• Boost oxygen and nutrient flow to each follicle
• Extend the hair’s growth phase and reduce breakage
Ideal for: Anyone with chemically treated, over-styled, or stress-weakened hair.
