Hair Growth Kit
A complete, clinically-inspired system for real hair regrowth.
Why it works
Formulated around the biology of hair loss
Hair thinning isn't a surface problem — it happens at the follicle level. The Hair Growth Kit is built around two ingredients specifically studied for their role in follicle activity and scalp health.
Derived from turmeric callus, Capilia Longa has been studied in clinical settings for its ability to reduce hair loss and stimulate new follicle activity. In independent studies it has shown a reduction in hair loss of up to 89% and an increase in hair density of up to 52% over 150 days.
GHK-Cu is a naturally occurring copper peptide widely researched for its role in tissue repair and scalp regeneration. It helps reinforce hair fibre structure at the root, supports scalp barrier function and has been studied as a stimulator of follicle activity since the 1970s.
What our customers say
Real results
Hair loss doesn't have to be permanent
Most men accept thinning as inevitable. It isn't — when you treat it at the follicle level, before the window closes.
Real Odenson customer. Consistent daily use over 150 days. Individual results vary.
How to use it
A 5-minute routine. Nothing more.
Start with a clean, dry scalp to maximise serum absorption.
Light, even pressure in multiple directions. Stimulates blood flow and opens micro-channels for the serum.
Apply directly after rolling. On non-rolling days, apply on its own.
Spray cleanser on the roller head and air dry. Keeps needles effective and your scalp protected.
How it compares
Why the Odenson system
There are a few ways to address hair thinning. Here's an honest look at how they compare.
~ = partial or conditional benefit. Minoxidil requires a prescription in some countries and can cause scalp irritation and increased initial shedding. Hair transplants start from ~15,000 USD and carry surgical risk.
What to expect
Your 150-day growth journey
Hair growth is gradual — here's an honest picture of what most users experience and when.
The first sign the scalp is responding is usually reduced shedding in the shower. You may also notice your scalp feels different after rolling sessions — this is normal and a good sign.
Scalp condition visibly improves — less dryness, less irritation. Fine, light regrowth may begin appearing in thinning areas. Existing hair often feels stronger and looks healthier at this stage.
Most users notice new growth along the hairline or crown. Hair looks noticeably fuller in thinning areas. This is the milestone most users first share with friends or notice in the mirror.
Stronger, thicker-looking hair with improved density. This is the full commitment window the kit is designed around — and the deadline for claiming your money-back guarantee if you haven't seen improvement.
Frequently asked questions
How often should I use the Hair Growth Kit?
Scalp Derma Roller
Use the derma roller 2–3 times per week on thinning or affected areas. Always clean the roller before and after each use with the included roller cleanser to maintain hygiene and protect the scalp.
Hair Growth Serum
Apply the hair growth serum daily. On days you use the derma roller, apply the serum immediately after rolling. On non-rolling days, apply the serum on its own to support scalp health and ongoing hair growth.
Do I need to keep using the kit to maintain my results?
Once new hair growth has progressed and fine vellus hairs have matured into stronger, thicker terminal hairs, you won’t need to use the Hair Growth Kit as intensively as during the initial growth phase.
For maintenance, we recommend:
- Using the scalp derma roller once per week
- Continuing to apply the Hair Growth Serum regularly to support scalp health and follicle function
Ongoing maintenance helps preserve hair density, support the natural hair growth cycle, and keep the scalp in optimal condition — especially if you’re prone to thinning over time.
Can I cut my hair while using the Hair Growth Kit?
Yes — you can continue to cut or trim your hair while using the Hair Growth Kit. Trimming the hair length does not affect how the follicles function or how new hair grows from the scalp.
That said, if you’re targeting specific thinning areas, it’s best to avoid shaving the scalp completely during the active growth phase. Keeping some hair length can make it easier to monitor progress and allows the scalp to stay better protected, especially when using the derma roller.
The Hair Growth Kit works at the follicle and scalp level, so regular haircuts won’t interfere with results as long as the scalp routine remains consistent.
How long does one bottle of Hair Growth Serum last?
Each 100ml bottle should last approximately 50 days if you use 2-3 pumps per day.
How long does the Scalp Roller last?
With proper care, the Scalp Roller should last up to 6 months. If the needles become dull or damaged, it’s time for a replacement to ensure the best results.

Most men wait until thinning is advanced before acting — by then the window for results is significantly smaller. The earlier you treat it, the more follicles there are left to work with.
