This is a high-end hair care product and worth experiencing.
First of all, about the packaging, the mask is contained in a opaque white core inside and is covered by a transparent green plastic layer that looks very luxurious and feels quite sturdy in the hand.

There is no scent. The packaging has all the details on it and how to use it. The texture is nice and smooth. For effectiveness it's hard for me to say if works. It did not really do the job for me. But I take showers at night. I think it would work if you took the time to do your hair.

I like things simple when it comes to my hair. I'm a wash, product and go girl. My hair has recently undergone a change and became extra dry. Leave in conditioner kept weighting my hair down. This product has been amazing! It gives moisture without the weight. Not only that, but it increases smoothness in the texture. My hair has continued to look better each day i use this.
Soooo good!

Secondly, I have noticed that each strand increasingly appears & feels smoother which makes which enhances the shine of my nearly 50-yr-old hair!
