Last week I purchased this hair serum for the first time and I am blown away with how much I love this product. A little goes a long way and my hair is incredibly soft and luxurious feeling, not greasy, oily or weighed down. I have never been more happy with a purchase and that surprises me. For me, most products like this end up in the garbage can. Thank you for making this product! I am anxious to try another product in this line.
