Lately, my ends had been really dry, to the point of feeling like they were split even though they are not, from the last time I had my hair highlighted. I typically only use a few drops after I've straightened my hair to keep it from frizzing. The other day, however, I decided to use a couple of pumps--not drops, but whole pumps--and only on my ends. My hair has been great ever since, no joke, after doing this just a couple of times and without any greasy feeling or weight. I highly recommend this! Also, I've had this sample for what seems like a long time, and it's lasting forever.
