I bought this on a whim as it was pretty inexpensive so I thought what the heck. As you get older your hair starts thinning, at least mine has. You can massage a few drops directly onto your scalp or add it to your bottle of shampoo. The simplicity of adding this to your shampoo was especially appealing for me so that’s the route I’m taking. I can’t say it has helped as it’s too soon to tell, but I can say it hasn’t hurt anything. I’ve used it 3 times and am keeping positive thoughts that it will thicken my hair. I’m a huge essential oil user, and since this contains ginger, angelica and ginseng I was attracted to this from the get go. It’s like a healthy cocktail for your hair.
