shampoo, 1 bottle say saint ives for coloured hair = rm50? lasts 2 months washing hair twice a day, 4 months for once a day washing, dont wash like they do in hair saloons where they double wash and such.

i would have thought everyone already has shampoo costs calculated into their monthly expenses, so i didnt bother to write shampoo expenses in. i guess not everyone uses shampoo on a regular basis
