How do I go about applying Lipogaine on my long hair/Daily routine question

[sts9]

i don't know if it's all in my head but i feel like i'm a really good responder to this lipogaine topical solution and the big 3 shampoo. i'm only on day 4 of applying (2x daily) and the mid section/front of my hair feels noticeably thicker and added volume and my crown is definitely getting some life to it without a doubt. i wish i would have got on lipogaine years ago
