While I haven’t found any studies exploring the benefits of apple cider vinegar rinse for hair there is plenty of anecdotal evidence .
Apple cider vinegar when diluted with water can help restore the natural pH of the acid mantle of your hair and scalp. It also contains natural AHAs which gently exfoliate the scalp removing build up of skin cells and hair products.
How much you need to use varies from person to person, but start with 1 tablespoon of vinegar to a cup of water, adjusting the dilution up or down until your find what works best for you. As a rule of thumb dry hair needs less apple cider vinegar than if you have oily hair or an oily scalp.
You can use a simple dilution of water and apple cider vinegar, but try adding a few drops of essential oils –
Mix 1 tablespoon apple cider vinegar with one cup distilled or filtered water. Add 5 drops of rosemary or lavender essential oil.
How to use: You may only need the vinegar rinse once or twice a week. Experiment to see what works best for you.
After shampooing your hair put your head back and pour the rinse over your hair and scalp. Leave for a couple of minutes then rinse. Using a squeezy bottle or similar makes application simple and cuts down on potential spills.
Any lingering vinegar smell will go once your hair is dry.
