The end!

I think you are probably right. I figure the water in the product settles to the bottom a bit over time. That is probably why it says on most bottles to shake well before each use. What really gets on my nerves is when you have a pump bottle of body lotion and you get near the end of it, there will still be quite a bit of lotion left in the bottom of the bottle, but the pump will not bring it up. So if you don't want to waste the lotion you end up haveing to either cut the bottle so your hand will fit in or turn it upsidedown and try to get the lotion into another container.

Yep, I sure do especially products for the hair that are in tubes. I don't like to blowdry my hair since it's so fine and basically dry. I prefer to use a gel after getting out of shower and letting my hair by itself since it will dry in less than 10 min. When I get near the bottom of the tube, it doesn't seem quite as effective. Like it loses some of it's "pick me up, fix me up." I get up in the morning and look like Alfalfa.

I think mine do and they do lose that zing. By the time my hair products are half used they start losing that greatness that they used to have. Perhaps next time we should check for an expiration date this way we know how long until we have to toss the product.

I do not have a problem so much with hair products but do find some skin creams go a bit yellowy rather than stay white after a time so I tend to open new. I know with some products you are only supposed to use for six months after opening but never check expiry myself. Best hair product that I have found that last is pantene leave in conditioner. Fantastic and can put on wet and dry whereas others can leave hair sticky. Ellie :)
