I had weightloss surgery and lost a lot of hair from it, which is typical. My hair stylist recommended Milkshake because it was natural and didn't have the chemical that grows hair back when you use it, but the minute you stop, your hair falls out again. Her other client who had brain surgery saw regrowth really quickly so I knew I wanted to try it. This spray feels like I'm praying water in my scalp, and leaves a mild minty feeling and smell. It wears off quickly and feels so nice on my scalp. I have fine hair so residue was a concern (like from serums), and this leaves absolutely no residue. My scalp stays healthy so no drying/flaking either. I've seen so much regrowth that I was dealing with all my baby hairs popping up! Now they are longer baby hairs and close to be long enough to lay flat. I saw regrowth and a reduction of loss within about 30-60 days of use. Thanks for making a natural, affordable, and effective product!
