One of the benefits of apple cider vinegar is that due to its acetic acid content, rinsing with it (after shampooing and conditioning) can help control the bacteria and/or fungi that can cause scalp and hair problems.

These include product build-up, itchiness and dandruff.

If you're squeamish about using something that's used for cooking on your head, we've discovered a beauty girl’s secret: There are commercial beauty rinsing vinegars.

It was Ira Nopuente of cosmo.ph who first tipped us about Yves Rocher Raspberry Rinsing Vinegar and its benefits.

After two uses of this product, spaced two days apart, our hair and scalp were free from itching and build-up. It was also shinier and it seemed healthier.

Korean brand A'pieu also has a hair vinegar, as we are sure do other brands.

Start with a vinegar rinse after you shampoo and condition. Make sure your hair is not dripping and apply the product on the scalp and hair, massaging thoroughly. Leave on for 2-5 minutes before rinsing. Tip: We use a spray bottle to apply the product.
