A mask with banana will be primarily for your hair length to add shine and structure to your hair. But it can also be a nice nourishing option for your scalp, BUT note that not every scalp type will necessarily react well to a mask like this so do first a patch test before applying it on your whole head to see if you get any itching, oiliness or redness from it. To apply it, brush this mask throughout the ends first and work your way up the strand. Put on a shower cap and allow it to sit for 30 minutes to one hour. Then, wash the mask off under running water with a scalp massager, then work shampoo into your hair and scalp thoroughly.The banana can be tough to wash out.
