Dandruff, dry or itchy scalp are the most common problems, to treat it with home remedy all you need is a lemon. Lemon alone can be very drying so mix lemon juice with few drops of olive oil to moisturize your scalp. If you have an oily scalp then use lemon on its own. Squeeze a lemon to the crown of your head and massage it into the scalp for few mins. Leave it on for 5-10mins and rinse off.
Follow up with a regular shower.
You can also add few drops of lemon juice to your shampoo or conditioner to treat dry, itchy scalp, massage the shampoo for few mins before you rinse off. The acidity in lemon will exfoliate the scalp, removing the dry skin and dandruff.
