Ultrasound treatment at 30khz shown to significantly inhibit DHT-induced secretion of catagen-related factors in human dermal papilla cells

Induction of hair growth in hair follicle cells and organ cultures upon treatment with 30 kHz frequency inaudible sound via cell proliferation and antiapoptotic effects (spandidos-publications.com)   <------ LINK

Saw this on reddit.  Here's the poster's TL;DR:

 

Some interesting bits:

• 30khz ultrasound exposure for 4 hours a day grew hair significantly faster than control, and even faster than minoxidil (but not significantly faster than minoxidil)

• Expression of balding-related genes that normally occur as a result of DHT was significantly reduced in the ultrasound treated samples (potentially stopping the hair-loss effects of DHT without needing to remove DHT!)

• This study is the first to report this phenomenon (published less than 1 month ago.)

• Measurements of gene expression were taken 2 days after treatment and the results were still significant

One downside:

• Researchers used 144 dB amplitude ultrasound, which is above the safe exposure limit of 110 dB for continuous ultrasonic exposure, meaning it might be difficult to turn this into a safe, practical treatment.

However, we have no idea if this level of loudness is necessary to produce the results in the study. 144 dB was the only loudness tested: it might work just as well, or even better, at lower amplitudes. Additionally, we have no idea if 30khz is the optimal frequency, and we have no idea if 4 hours per day is the optimal "dosage" of ultrasonic sound. More research of this phenomenon is necessary to answer these questions.

it's time to rethink baldness if someone is willing to risk radiation exposure for more hair.

Yeah, 4 hours a day vs 15 mins application of Minoxidil and barely any extra benefit, i think the dedication would kill adherence. 

Hell, most give Minoxidil up because they think they don't see results.
