Great results.
I have been using it for a year great results. I have hair similar to Caroline's with thinning at the temples. I am filling in nicely. We are also close in age for reference.

Works but makes your hair sticky
This does work as I’ve seen baby hairs growing in..but it’s sticky & clumps your hair together and you can’t just style your hair as usual! I suggest using it at night before bed so you can wash it out the next morning BEFORE you style your hair! Wish it had a nice citrus scent!

Formula doesn’t leave a residue.
I have noticed new hair growth more on my crown than anywhere else. I love how the formula disappears and does not make my hair greasy or flat before I style it.
