Onion juice can help with hair loss according to science.
For one, onions are high in dietary sulphur, a nutritional element our bodies need.
Sulphur is found within amino acids, which are components of protein.
In order to grow strong hair, proteins which are sulphur rich are needed and this is where onion juice comes in.
When added to the hair and scalp, onion juice can provide extra sulphur to support strong and thick hair, thus preventing hair loss and promoting hair growth.
