I feel like this has been a holy grail hair product for many women for a long time, including me. Everything this leave-in conditioner says it does it does; I mainly use it as a detangler after I get out of the shower and my hair is still wet. I let it soak into my hair and than use a wide tooth comb and comb through my hair; it is so easy to get through with this product! No tugging or losing clumps of hair! This leave-in is also repair split ends, add shine, create silkiness, keep color from fading, and seal and control frizz. I literally feel as if this does all of those things. I tend to have split ends no matter how little heat I use, no matter what products I use for my hair, and no matter how gentle I am with my hair. I believe when I get my haircut the hairdressers thin my hair out (without me asking for it) and it has caused alot of damage with my hair. However, this formula is gentle on my hair and I use it every time I was my hair (every other day.) It does not weigh my hair down, does not make my hair look or feel greasy, and I love using it with my hair oil of choice-right now my Morrocanoil. I have come to except the fact that better quality hair products are pricier but the $18 price tag for 4 ounces really isn't that bad to me as I don't go through it too quickly because I don't shampoo everyday. I received a sample size from a family member and I love filling it from the bigger one when I am scheduled to travel. One of the added perks of this leave-in aside from the fact that it's already a 10 is the smell! It's so heavenly! It's such a clean, luxurious smell; it makes me excited to style my hair! If you have never used any It's a 10 product I highly recommend starting with this one first-it's sure to please!
