I got this because I had some thinning along my hair line and wanted my many "baby hairs" to stop sticking up all over the place and needed something to help them grow. It's only been a month in, but I can already tell it is working. What I do is every night when I am doing my nightly routine washing my face/brushing teeth I first wash my face/get all my makeup off, and once I have used my cleanser then washed off I use this. I use this before putting my toner and serums on. I apply it all along the hairline and since this bottle comes with a dropper, it makes it precise and helps it not go everywhere. After I apply a few drops all along my hairline on my forehead I gently rub it in with my fingertips and then take a brow brush or brow spool and brush it in and back like im going to put my hair in a ponytail. I let that sit for about 20 minutes then wash it off with water. This is particularly good on nights if you use or apply masks or skin treatments, because you have to let the mask sit for a certain amount of time so doing this with it helps take care of both at once. I have also started to use this on my eyebrows as well to help with over plucking so I can grow my eyebrows back in and its really actually working! I have been trying so long to try and get my sparse hairs to grow in and full and nothing has worked but this stuff. I take a few drops and put it on each brow and rub it in the brow line then take a brow spooling and brush it in. Wait about 15 to 20 minutes then wash out with water then your done. The key is consistency and this will work. The smell is like a cleaner version of like a Vicks Vapor rub, but not super strong. I love using this stuff at night because it opens up my nasal passages before bed. This product comes in a glass jar with a glass dropper and rubber dropper head. This stuff really works! This stuff has done so good so far I can't wait to see what a few more months will do. Next I am going to start trying this stuff in my hair for split ends and I have full faith they are going to start looking fabulous 👌Update** I'm so mad at myself, because I wish I would've taken a before picture to put with progress photos to show how much this has had an effect on my hair growth! This is doing great for my hairline, but I noticed alot of the reviews on this was for baby hairs and for regular hair growth, so I wanted to put forth some info on if and how well this does for other areas such as eyebrows, and let me tell you, this stuff is absolutely AMAZING for that! The photos above are my eyebrows at about 3 to 3 and 1/2 weeks in using this product. I only had hair where the inside of the green boxes are, and honestly the picture doesn't do it justice, because this product helped fill in those areas too. All the outside of the green boxes is from using this product. I cant believe what I'm seeing grow, it's amazing :) The picture with my lashes is to show where I apply this along my lash line where the green line is. Those are my natural lashes with nothing on them and this stuff has made them full and longer. (I do not apply the dropper itself along the lash line, after applying to my eyebrows and hair line when rubbing the product in I use what is left on my finger and swipe gently along the lash line.) I will update again to post another photo of what it looks like once I get to the 2 and 1/2 to 3 month mark.
