What Happens When RF Is Applied to the Scalp?2026.03.21
The Relationship Between Temperature and Regeneration
“What exactly does RF (radiofrequency) do?”
This is a common question in scalp treatments.
The answer is simple:
RF activates regeneration by controlling temperature.
Unlike lasers, which target pigments,
RF works by raising tissue to a specific temperature, triggering biological responses.
How Do Cells Respond to Temperature?
Human cells are highly sensitive to temperature.
When RF generates heat in the range of approximately 40–45°C,
this is not simple damage but rather:
A controlled biological stress
This triggers:
- Heat shock protein (HSP) expression
- Activation of fibroblasts
- Collagen and elastin remodeling
In other words:
Temperature acts as a trigger for regeneration
Why Apply RF to the Scalp?
In the scalp, several important changes occur:
① Improved Blood Circulation Around Hair Follicles
RF-induced heat dilates blood vessels, leading to:
- Increased oxygen supply
- Improved nutrient delivery
This directly contributes to:
Creating an environment where weakened follicles can recover
② Remodeling of Fibrotic Tissue
In AGA, the scalp often shows:
- Stiffened tissue
- Restricted follicular movement
RF helps to:
Soften and remodel the surrounding tissue
③ Activation of Hair Follicle Stem Cells
Through thermal stimulation and wound-healing responses:
Dormant hair follicles may become active again
Why Temperature Design Matters
RF is not effective if used randomly.
- Too low → no biological response
- Too high → tissue damage
Therefore:
Controlling the optimal temperature range is critical
Why Morpheus8 Is Effective
Morpheus8 allows:
- Direct energy delivery into deeper layers via microneedles
- Precise control of depth in millimeters
This enables:
Targeted temperature delivery to specific layers
such as:
- Dermis
- Subcutaneous tissue
- Hair follicle surroundings
The AVAN TOKYO Approach
At AVAN TOKYO, we focus on:
Designing temperature, not just applying energy
We carefully control:
- Depth
- Energy level
- Treatment area
to create:
The optimal environment for follicle activation
In addition, combining with stem cell conditioned media:
Enhances regenerative signaling
Final Thoughts
In hair restoration, the key is not simply stimulation.
It is creating the temperature at which cells respond
“Regeneration Can Be Controlled by Temperature”
Scalp treatment is evolving from:
“Applying or taking treatments” → “Designing the biological environment”
At AVAN TOKYO, we integrate:
temperature, depth, and regeneration
to maximize the natural regenerative potential of hair.
