In a study with the US National Library of Medicine National Institutes of Health, hair-loss preventing the effect of Grateloupia elliptica was analysed.
The study noted: “This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss.
“When immortalised rat cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased.
“In addition, the G. elliptica extract significantly inhibited the activity of 5α-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia.”
