Very pricey but for the amount I choose to use the bottle will last a long time.
I agree this stuff is expensive. My sense is that, regardless of your age, one 5 oz bottle will last your lifetime. I know it will last mine. As a philosophy major, I don't trust myself to make a home brew...It sounds like a nice product...but I do have some sticker shock.
I'm hard put to see what makes this blend any more effective than using, say, just argan or jojoba oil (both of which I've used and like).
I also just got a couple of good-sized bottles of apricot oil on sale at my local health-food store....also good for skin and hair.
