Rapid Lash works well for some, but not all. I also lost a lot of my lashes after wearing lash extensions for a year or so, and false ones for many years prior. Mine came back after taking BioSil. So did most of my eyebrows and hair which had thinned from age. Suddenly, I had to have my nails filled every 2 weeks, not 3 and had to do my colour touch up sooner too....but there is a price for all progress
I use the liquid, as the pills are too $$ and don't work as well. Its quite nasty tasting, so bury it in a strong tasting juice like apple or cherry, OJ is too acidic. You use 10 drops and I use a shot glass size of juice to mix it with....hold your breath and chug it
The liquid is better absorbed and used by your body, and will work quicker too. It took about 3 months before I saw results, as it takes a while for your lashes to grow, but they went back to the lashes I had when I was younger. Mine had also thinned from age, as had my hair and eyebrows.
BioSil will also help your nails, which is where you will notice it working first as nail growth is a tad faster or you just notice it more, your hair, where you will see little fuzzy new hairs around your hairline first, and your skin, which will have a nicer, plumper, firmer look and its good for your bones too, gives you some protection against thinning. Yeah, I should own stock in the company, I love it that much! For a simple reason, IT WORKS. So many other things don't, or just work for some. BioSil so far has worked for everyone I've recommended it to, it just takes time.
I have used RL for over 3 months now and it hasn't done anything. Not sure why as so many others get great results and have picture proof that it worked. I envy them so much! No improvement in my lashes at all, but I will press on until the entire tube is done. I did hear some dermy doc say that all any of the lash growth products can do is to give you the lashes back that you had when you were younger, as it won't make new hair follicles appear, but has to work with what you have. Kinda makes sense, even if its not what I want to hear, as my lashes always were sparse and I really want the look I had with the extensions, full, long and lush. Its worth a try if you have the extra $, but I'd go for the BioSil if you have to choose. Way more bang for your buck and good for your entire body. HTH!
