i have read thru this looong thread and i must say its really informative.. since i gained more than a handful of useful price information, i thought i should contribute alittle of my own findings ..
personally, i have been using nizoral for about 6 months, and have been varying the doses to test effectiveness.. here is what i found out with regards to hair loss..
2% Nizoral -
very effective in stopping hair loss i.e. esp for the following day, hair loss is drastically reduced barring any onset of illness (yes getting sick seems to cause hair to fall more readily).. but 2% is too harsh (scalp feels funny) so i downgraded to 1% with conditioner..
1% Nizoral -
wasnt very effective when i first started.. hair loss is reduced slightly only.. and after many many trial and errors.. i found that the best effect i got is to shampoo normally first (i suggest something moisturizing.. i use dove shampoo) to get rid of all the dirt that might prevent Nizoral absorption
then i use the 1% on the scalp and massage scalpe for 3-4mins.. okay massage is not very important but
leaving the nizoral on the scalpe for 3-4 mins is VERY important; MUST have discipline here
another point to add, i use nizoral 1% EVERYDAY because i notice when i use EVERY OTHER DAY, i will experience cycles of increase hair loss

(note: altho instructions say to shampoo twice each application, i only do it once after normal shampoo.. seems like no effect on hair loss so save the nizoral 1%)
sorry for sounding like a broken record but i must stress the discipline in letting nizoral 1% rest on your hair for 3-4mins.. there were times when i didnt maintain discipline, hair loss increased and wondered if nizoral is losing its effect for me..
I should also add that i am using minoxidil for hair growth (Growell 5%) and it seems to be working well.. but is alittle heavy on the wallet at $78 for 60ml @ NTUC.. I am thinking of buying online.. Kirkland - any issues with this brand? i understand some are having scalp problems with this.. if not recommended, i might go for the more expensive Rogaine?
Anyone can recommend an online brand i should use if Growell is working for me?
