I have a few questions regarding these two substances,

(a) As a 27 year old, NW 2.5 heading toward NW3, how much would it cost on a weekly and monthly basis to maintain what I have using these two products? For instance how much is a bottle/ box of each on average, and how long would they last for?

(b) What would be the ratio for them maintaining hair in individuals – would it be nearly 100%, or 75%, or as low as 50%.

(c) Do these products thicken hair, or perhaps even cause regrowth of hair at the temples, and on a lightly visible bald patch at the back?

Thanks.
