I received a sample of this in my Birchbox and it has lasted absolutely forever. I love the smell - it's faint and reminds me of my grandmother (not in a bad way, more in an old fashioned smell kind of way). I blow dry my hair halfway and then use one small squirt to run through my damp hair. It leaves my hair so silky and smooth after with the faint hint of the seaberry smell. I don't know if I can afford to buy this again, it is very pricey, but it will last a very long time.
This is a wonderful hair serum. It smells amazing and keeps hair from drying out. It does not weigh down my hair and does not make it oily either. It made my fine, dry ends feel conditioned but not limp. It works great as a detangler if used before brushing. A little bit goes a long way, so it should last quite a while.
