I love acv for my hair too... with warm water of course. I have started masaging in coconut oil. I will tell you how it goes.

Causes of itchy scalp range from dry skin to fungal infection and Apple cider vinegar is one of the most effective ways of treating itchy scalp. This is because of the anti fungal and anti bacterial properties of apple cider vinegar which will deal with the root causes of the itchy scalp.

A straight forward way of treating itchy scalp is to apply apple cider vinegar to the root of your hair and allow it to stand for 30 minutes before washing your hair. As stated above the apple cider vinegar will kill bacteria and fungi that might be causing the itchy scalp.

Another way is to combine apple cider vinegar with other herbs such as rosemary, lavender, lemon and sage. You do it by first putting two teaspoons of the herb in a muslin cloth and pour boiling water over the herb to infuse them. Mix the resultant herbal infusion with apple cider vinegar and apply it to the scalp and rinse after 30 minutes.
