This review synthesizes current research on onion-derived preparations for scalp and hair health, highlighting their potential benefits in hair regrowth, microbial reduction, and follicular support, while noting gaps in standardized formulations and controlled clinical trials.
The conversation discusses using onion juice and coconut oil for hair loss, with mixed opinions on its effectiveness. Minoxidil and finasteride are suggested as more reliable treatments.
Castor oil may reduce DHT and help with hair growth, while onion juice lacks evidence for effectiveness. Alternatives to natural topicals include RU58841, olive leaf extract, baicalin, and curcuminoids.
A 29-year-old male experienced hair loss and found improvement using a combination of onionhairoil, castor oil, ketoconazole shampoo, and aloe vera gel with vitamin E, while discontinuing minoxidil and finasteride due to side effects. He emphasizes the importance of scalp massage and oiling for hair growth and reduced hair fall.
Minoxidil can cause significant hair shedding, especially for those who don't need it, and should be used cautiously under medical advice. Natural remedies like onion, rosemary oil, aloe vera, coconut oil, and a healthy lifestyle can help recover from minoxidil-related hair loss.
The conversation concludes that the hair is a wig or hair system, not a real transplant. Some users humorously suggest treatments like finasteride, minoxidil, rosemary oil, onionoil, scalp massage, and prayers.
