in looking at the ingredients i bet the lecithin is the thickener.
'more concentrated' isnt the same as 'thicker'. more concentrated would mean more than 3% and that would be more than max recommended. email reply from the reviv serums guys:
The percentage of Redensyl in our Hair Stimulating Serum is 3%, the strongest formulation percentage recommended by its Swiss inventor Induchem AG for a once-daily application. The 60 mL bottle should last between 37 to 75 days (about one to two full droppers, 0.8 mL to 1.6mL, once daily). The measurement does not need to be exact, and we recommend applying enough serum for good coverage. For some, this might mean using more product than the instructions specify.
