For hundreds of years the onion has been one of the most used hair remedies to treat hair problems or simply to improve its appearance. There are many beneficial properties attributed to the onion, such as the ability to accelerate hair growth, eliminate oil from the hair, stop hair loss and delay the appearance of gray hair.

We now know that its attributes are purely due to its two main active ingredients, Quercetin and Sulphur (also known as the beauty mineral).


Dioscorides was a doctor and botanist in Ancient Greece. He wrote the masterpiece ‘DE MATERIA MEDICA’ (Latin name for the Greek word: “medical material”) which it became the reference medicine manual for more than 16 centuries. His work brings together information and studies on medicinal plants, animal products and minerals. Dioscorides carried out one of the greatest tasks of research and data-gathering to create the largest and oldest pharmaceutical guide known. Its texts were translated into multiple languages ​​and widely distributed until the 16th century. In De Materia Medica, he describes the properties of onion, its many benefits and its properties as a hair remedy: “…by friction, for bald spots, as it causes faster hair than the false sponge ”.

JOHN GERARD (London, 1545–1612)

In 1597 John Gerard was an English naturist, herbalist and surgeon who published The Herbal or General History Of Plants, a book dedicated to the study and analysis of different plants. He describes the characteristics of each plant and their properties. It became one of the most important and consulted books of its time. In chapter 93, page 171, the author refers to the onion and its properties with the following comment: “the juice of onions anointed upon a pild or bald head in the sun, bringeth the hair again very speedily ”.


There is currently a study published in the Journal of Dermatology in PUBMED by Dr. Sharquie KE where he examined the results of onion juice applied to the scalp in 23 people suffering from alopecia areata. Those 23 people had onion juice applied twice a day for two months. Participants began experiencing hair growth after just two weeks of treatment. At four weeks, hair regeneration was observed in 17 people and in 6 weeks hair growth was evident in 20 people. The study concluded, after examining the results, that the use of onion juice as a natural and home remedy for people with alopecia areata problems had a very beneficial effect.


Currently, there are multiple reviews on the internet of women and men using the properties of onion as an aid to accelerate hair growth or to eliminate oil and dandruff. These reviews can easily be found on the Internet, YouTubeforumsmagazines and websites.

Many beauty secrets are published by different high traffic blogs where they present the benefits of onion as a hair remedy reassuring that hair can indeed grow 2.5cm in a month, (well above the usual average).
