Review title is Product is great; but the packaging needs to be fixed... [SEP] - As I noted in the title, the *product* is as described.  I use it for various things, not my hair (what little there is of it, LOL!), but it's a good strong peroxide for those NON-health instances where one needs a good strong peroxide.<br /><br /> - The one problem is with the packaging:<br />The caps are just half a hair's width too long for the neck of the bottle, and that's why people have had problems with leaking bottles.  If just maybe 1/16th of and inch is shaved off the bottom of the cap, it screws down tightly and No More Leaks.  I might have cut a bit more or a bit less off of my cap; I didn't measure it exactly, but it proved the principle.<br /> - Anyway, if just a shorter cap was used for packaging, it would prevent leaks.
