It's a product I've used many times and will definitely use again, and the effects are noticeable if you continue to use it. I have long hair, so I pump it about six times, and it's a great value for the money, so I love it.
I received the mist and milk as a gift. Thank you for being my first winner. I've used several La Sana products over the years, and I think the mist is consistently easy to use and perfect for busy mornings. However, I honestly think the Silky Hair Spray has a better scent, shine, and smoothness. The milk isn't sticky or heavy, and it does feel like it protects my hair, but I didn't feel like it kept it moisturized as long as the oil.
I bought it because my favorite idol is an ambassador for it.
I've been using La Sana's leave-in treatment Hair Essence for about 20 years (though I've been unsuccessful with other products). While this hair mist isn't as effective as the Hair Essence, I've been a regular customer for quite some time, but I haven't used it in a while. So, I finally bought it. I apply the Hair Essence the night before, blow-dry my hair, then spritz it on the next morning before brushing (my current favorite is the Aveda paddle brush). It calms my hair and makes it feel nice. It's La Sana after all. The mist is great, too.
It has a nice scent and when you apply it, your hair becomes smooth and tangle-free.
