you can try the loreal spray.
it is just like water, and when u spray it to your hair will be firm but it won't be too hard and its non-sticky as well.

yeah i think that this one is just great for you and ts.
it gets your hair firm, but it wont make it sticky, and you wont get that really wet look effect.
looks really natural but still firm.

and yeah, it is widely available.
pharmacies, even supermarkets also got.

yes, it is loreal fx style o water, not gel o water.
gel o water is a different one, where it is very sticky and all.

the one that i posted is more towards hair styling.
a hair serum is more towards nourishing, as in long term, it'll make your hair better, or so they claim.
i've used some serums before. it's good, makes your hair softer, but you have to use it everyday. once u stop, your hair will become like normal.
plus, it does not have that 'holding' effect.

so, it's your call.

it's quite expensive, since it's loreal.
last time it was Rm19+ i think.

i think using hair conditioners everyday won't cause any problem like grey hair.
as long as you're using a normal, everyday product, i think there's nothing to worry about.

wow you bumped my post from 2 years back

anyway, i still see a lot of the spray being sold all over the place
still in production
so my answer would be,
tesco got
