Extra effort for little payoff
[Received in exchange for my honest review] So, I've been testing this overnight serum for a few weeks now, and while it's not bad, it's also not something I could foresee being a holy grail, either.

[I received this product in exchange for my honest review] The packing was literally just in a brown box. The smell is not the best but not the worst. It really did make my hair soft and shiny. This is a very good product and I would use it again!!!!
Frizz free & healthy shine!

On days I don't use it there is a drastic difference in the appearance and feel of my hair the next day. I don't notice a long term difference from wash to wash, but my hair appears more youthful and healthy with it.

I would buy this product again and again

I received this product free to give a honest review on so here it is. Just buy it! I put this in dry hair at night, and woke to the softest hair ever! Easy to maintain and less frizz. I would recommend washing your hair the next morning, but the softness carries over to your clean hair making styling a bit easier also. Have definitely noticed less breakage
I would buy this product again!
