Plinest Hair Polynucleotide Treatment
Plinest TM Hair (Polynucleotides) & Medical Microneedling
If you’ve noticed your hair is thinning, shedding more than usual, or looking less dense, it can feel frustrating- and sometimes overwhelming. PlinestTM
Hair is an injectable polynucleotide treatment designed to support the scalp environment and encourage healthier-looking hair over time. It’s a popular option for people who want a non-surgical, regenerative-style approach to hair and scalp support.
At Dr Fiona Steedman Aesthetics, treatments are tailored to your goals, your scalp, and your lifestyle-with a focus on subtle, natural-looking improvement.
What is Plinest Hair?
PlinestTM Hair is a highly purified polynucleotide gel delivered via small injections into the scalp (intradermal microinjections). It’s presented in a 2ml pre-filled syringe and is specifically suggested for trophic action (nourishing support) on hair and eyebrows.
Polynucleotides used in these treatments are highly purified DNA fragments, commonly sourced from fish-derived DNA in medical-grade processes.
How does it work?
PlinestTM
Hair is designed to support the scalp by:
● Improving the quality of the scalp tissue (a healthier “soil” for the hair)
● Supporting hydration and elasticity within the skin of the scalp
● Encouraging a stronger environment around hair follicles over time
It’s best thought of as a scalp and follicle-support treatment, rather than an instant “hair growth miracle”. Results are gradual and vary by individual.
Who is it for?
Have diffuse thinning (often seen with hormonal or stress-related shedding)
Want to improve hair quality, resilience, and scalp condition
Are looking for a plan that can work alongside other hair strategies (topicals, supplements, LED etc.)
PlinestTM Hair has been discussed in the context of female hormonal hair loss, with clinical reporting of tolerability and patient-reported improvement in a small cohort.
It may not be suitable if hair loss is primarily due to an untreated medical cause (e.g., iron deficiency, thyroid imbalance)- we can guide you on what to check with your GP if needed.
Areas we can treat
- Scalp (most common)
- Eyebrows (selected cases)
Combination Approach: PlinestTM Hair + Microneedling with SkinPen™
For suitable patients, combining bio-stimulation (polynucleotides) with controlled micro-injury (microneedling) can address multiple pathways-scalp quality, microcirculation, and follicle signalling. Early data indicate combination protocols can improve hair density and shaft diameter compared with monotherapy.
What to Expect on the Day
Consultation
We’ll discuss:
● Your pattern of hair change, triggers, timeline
● Medical factors and medications
● Your goals (density, shedding, scalp health)
Treatment:
The product is placed into the scalp with:
● Microdroplet injections
● Intradermal depth

Aftercare & follow-up
You’ll get clear aftercare instructions and a plan for review.
How many sessions will I need?
Protocols can vary by clinician and individual, but Plinest™️ Hair protocols commonly describe:
● Phase I: 1 session every 7-14 days for 4 sessions
● Phase II: 1 session every 21-30 days for a further 4 sessions
Not everyone needs both phases-we’ll build a plan around your scalp, your shedding pattern, and your response.
Can Plinest Hair be combined with other treatments?
Yes-it’s often used as part of a broader hair plan.
If appropriate, we can discuss combination planning and what’s realistic for your goals.

Frequently Asked Questions
Does Plinest™️ Hair hurt?
Most people describe it as manageable. We can use comfort measures and techniques to reduce sensitivity. Scalp injections can feel sharp and “stingy” but are quick.
How long does the appointment take?
Yes-combination therapy can be beneficial.
Is there any downtime?
Minimal. You may have small bumps or mild redness in the scalp for a short period and occasional bruising.
How many sessions will I need?
Many protocols describe 2ml per session and a structured course (often starting with 4 sessions at 7-14 day intervals, then further sessions spaced 21-30 days apart if indicated).
We tailor this to you.
When will I see results?
Hair and scalp changes are gradual. Most people assess progress over 8-16 weeks and beyond.
Will it work for male pattern baldness (androgenetic alopecia)?
If hair loss is due to androgenetic alopecia, you may need a combined plan (and expectations must be realistic). We’ll advise honestly based on your pattern of loss.
Can I wash my hair after treatment?
Usually yes, but we may recommend waiting a short period. You’ll receive exact aftercare guidance at your appointment.
What should I avoid after treatment?
Common advice includes avoiding intense exercise, heat exposure (sauna/steam room), and alcohol for a short period post-treatment, plus avoiding scalp irritation. We’ll provide personalised instructions.
Is Plinest™️Hair safe if I’m pregnant or breastfeeding?
Injectable aesthetic treatments are typically not recommended in pregnancy or breastfeeding. If this applies to you, we can discuss safer alternatives and timing.
I have a fish allergy-can I still have polynucleotides?
Polynucleotides are derived from fish DNA sources.
If you have a fish allergy, please tell us-we may advise avoiding treatment depending on your history and risk profile.
Can I combine this with minoxidil?
Often yes, but spacing and sequencing matters. We’ll build a joined-up plan if combination therapy makes sense for your goals.
Are there side effects?
Possible side effects include redness, swelling, tenderness, headache, bruising, and (rarely) infection or inflammatory reactions. A full consent discussion happens before treatment.
