An Experimental Electric Comb May Stave Off Baldness

Key Points:

• Researchers at Beihang University in China developed an experimental electrical comb called "Detangle" that significantly promotes hair regrowth in mice with androgenetic alopecia, outperforming common treatments like minoxidil and finasteride.
• The Detangle comb combines electrical pulses with a unique tooth design to enhance the delivery of therapeutic molecules deeper into the skin, addressing limitations of current topical treatments that struggle to reach hair follicles effectively.
• In mouse studies, Detangle achieved nearly 100% hair regrowth on shaved areas after 28 days, compared to about 70% regrowth with minoxidil, without causing any noticeable skin damage.
• Androgenetic alopecia, caused by sensitivity to the hormone DHT, was targeted using a plasmid promoting blood vessel growth and SRD5A2 siRNA to suppress DHT production, both delivered via the comb.
• While promising, the technology is still in early stages and requires further research, including human trials, before it can be considered a viable treatment for the estimated 1.5 billion people affected by pattern baldness.
