I loved getting my hair washed. Its those little life pleasures that feels good, well priced ( dependng on where you go) and does not make you gain weight.
Its a good scalp massage, while removes those excess flaky dandruff, releaves head ache and relaxing.
I still remember when I was little when we still lived in Paka, Terrenganu, when my dad had a hair wash after a haircut in a salon. I still remember the foam covered wih bits of hair that was in a bowl.
I used to get my hair washed everymonth which was the same time I got my haircut because it was only rm 10 to do both. However this was at Arau, Perlis, where everything was well priced.
So why don't you try it sometimes.
