erm yes it wouldnt hurt, but then you spend unnecessary money on
accessories or shampoos or conditioners lor.
got a doctor told me, he once saw a man who went to buy shampoos
and conditioners, and he feel like telling him that is no use one,
better take propecia lol.
it's a placebo effect..
I don't find it's exactly unnecessary, cause you still would
have to wash your hair.
If it's to the extent of buying a $50 shampoo. yes that's
extreme.
But if it's $10.. and it really improves the condition of the
hair.. then haha most will swear by it
