Balsamic vinegar gives hair gloss, shine and a soft texture. It is also able to make the cuticles (that coat and protect the hair) swell slightly, giving the whole mane a more voluminous appearance. Why use a plum version of it? For the love of plums, of course!
Vinegars characteristically taste very sour; however, balsamic vinegar is distinctively different with a rich, sweet and sour flavour and thick, syrupy consistency. It is prepared from white grapes and wine vinegar. It is placed in wooden barrels and aged for up to 25 years. Each variety gains some flavour from the type of wood used for barrels.
The traditional method of production originated in Italy and has been used there for centuries. Makers of traditional balsamic vinegar are as protective about the status of the true aged varieties as you would expect a wine grower to be about the character of a good vintage.
Using various vinegars for cosmetic purposes goes back centuries and formed an important part of ancient hair rinses and skin treatments because of their acidity and ability to help preserve natural cosmetics.
