If you have 900 Hp with 8 Health Charms, the base Hp is 500. After 75 kills, 500 x 0.75 = 375 Hp will be subtracted and your Max Hp will be 900 - 375 = 525 (instead of 900 x (1 - 0.75) = 225).
The counter only resets if you unequip the hood. Otherwise, you will only lose the kills counted if you die or retry in an area, and only in that area. Any screen transition where xp/items are kept is sufficient to keep you kill counter.
