Utilizing Sound to Treat Hair Loss

Utilizing Sound to Treat Hair Loss

I have followed the hair loss world for over 20 years, and discussed it on this site for 8.5 years. However, practically each and every single month, I still checked out something on hair that completely surprises me. The most recent is courtesy of this thread on Reddit.

Sound Hair Growth

Biomedical Reports. Choi et al. Inaudible Sound Therapy and Hair Growth A brand-new study from South Korea that came out last month suggests a role for sound therapy in treating hair loss. It is entitled “Induction of hair growth in hair follicle cells and organ cultures upon treatment with 30 kHz frequency inaudible noise.”

According to the authors, these inaudible frequency sound waves favorably affect scalp hair through 4-hour treatments that:

  • Induce proliferative and anti‑apoptotic impacts in human dermal papilla cells (hDPCs) and external root sheath keratinocytes.
  • Prevent the unfavorable effects of dihydrotestosterone (DHT) upon hair growth.

The authors conclude that:

“Overall, the outcomes recommended that inaudible sound may work in dealing with hair loss and might be used to establish a new hair loss treatment method.”

They provide two hypotheses on why inaudible sound vibrations are triggering hair growth:

  1. The promotion of hair growth occurs due to activation of the Wnt/ β-catenin signaling path by means of the acoustic waves.
  2. The hair growth takes place as a result of mechanotransduction (mechanical tension) from the cell membrane of hair roots cells. This tension is an outcome of modification by the inaudible sound.

Note that uasound therapy and related gadgets are typically utilized to enhance drug shipment systems. In 2020, I talked about a study that utilized uasound activated nanoparticles to treat androgenetic alopecia. Also in 2020, I went over sonophoresis and radio frequency as new prospective ways to provide topical finasteride.

Molecular Vibrations

This phenomenon is not as incredible as one would anticipate. For many years, we have actually known that even things like low-level laser light (LLLT) treatment, massage/mechanotherapy, scalp wounding, and even friction can result in hair growth in some.

And in the way-out-there world, we have actually checked out anecdotal reports of hair regrowth on people who got unintentional scalp injuries from fire and even lightening. I believe I should hereon call all such phenomena as “molecular scalp vibration” stimulated hair growth.

The authors of this latest study cite a number of supporting studies. This consists of ones that recommend that low-intensity vibrations and sound effect the body at the cellular and genetic level.
