Exo-Grow® with Dermapen 4 Gold: The Next Generation of Hair Regrowth
Woman receiving scalp microneedling treatment with exosome solution applied between parted hair.
Hair thinning, shedding, and slow regrowth can be triggered by everything from postpartum shifts to stress, hormonal fluctuations, bleaching, or traction from extensions. For many, the solution isn’t another pill or lotion but a regenerative push that speaks directly to the scalp’s cellular environment.
At The Hair Clinic, we’re proud to offer one of the most advanced treatments available in New Zealand: DP Exo-Grow® exosomes combined with Dermapen 4 Gold microneedling. This cutting-edge treatment combination delivers cell-derived signalling molecules directly into the scalp, helping to awaken sluggish follicles, reduce inflammation, and stimulate visible regrowth.
Led by Dr Mark Morunga, NZ’s Key Opinion Leader for Exo-Grow, our clinic sets the standard for evidence-based exosome protocols.
What Is Exo-Grow® and How Does It Work?
Exosomes are microscopic vesicles that act as messengers between cells. They carry growth factors, proteins, peptides, and lipids that influence how nearby cells behave. In the context of hair loss, these exosomes improve follicular communication, reduce inflammation, and create a healthier environment for hair to grow.
The DP Dermaceuticals MG Exo-Grow® system we use is completely cell-free and does not rely on human or animal growth factors. Instead, it uses highly purified, medical-grade exosomes that promote regeneration without risk of immune response.
During the treatment, the exosome solution is applied directly to the scalp and infused via Dermapen 4 Gold microneedling, a device that creates micro-channels in the skin to enhance delivery and kickstart the body’s own healing cascade.
Treatment Process: What to Expect
As featured in BeautyEQ, the treatment begins with a consultation to assess your scalp health and suitability. Following this, a clinical nurse applies the MG EXO-GROW tonic directly to the scalp using a fine syringe, parting the hair to ensure accurate placement.
Microneedling then follows. Tiny channels are created to promote blood flow and stimulate a healing response in the skin. These micro-injuries allow the exosomes to penetrate effectively and encourage dormant follicles to re-enter the growth phase.
Most patients describe the sensation as similar to facial microneedling, as prickly with a warm or tingling feel. The session takes around 20 minutes, and it’s common to experience some tenderness or redness for 24-48 hours afterwards.
Post-treatment care includes:
Avoiding intense exercise, sun exposure, or hair washing for the rest of the day
Skipping salon colouring during your treatment window to spot new baby hairs easily
Following your at-home scalp care routine (provided as part of your plan)
Visible Results from 8-12 Weeks
While some patients notice less shedding within weeks, the most common timeframe for visible regrowth is between eight and twelve weeks, with improvements continuing over several months.
Reported benefits include:
Thicker, denser strands
Healthier scalp with less irritation or flaking
Increased shine and softness
Slowed or halted shedding
More active follicles visible under dermatoscopy
