It is basically black powder if I'm to put it honestly. Re toppik being cheaper, here in India it is 5-6 times more expensive so even though I can afford it. The opportunity cost is high.
I believe you're going to have great results (=completely like before you started losing them). Ein got his results after 5-6 months and you're already having awesome results after about 36 days on bica.
I believe Ein was having results earlier than that, within the initial months, but didn't notice the hairs until they grew longer. It would be the same case for others who have a great baseline. Since my hair was that bad, growth can be noticed rapidly.
