all you need is:
half a grapefruit
an egg,
a tablespoon of olive oil.
please do not include the grafefruit pulp as it can be quite disastrous, trust me on this. i thought its a good thing until i have to clean my hair twice to get rid of those pulps stickin to my hair. gosh!
and this is how you do it:
squeeze the grapefruit juice, beat up the egg and add in the olive oil. tadaaaa..apply it to your dry hair and leave it for 20minutes.
the result to me, is not very impressive. but still it does good for your hair.
