This Amazon eyelash growth serum is just $14 for Memorial Day

Many experience thinning hair on their heads, but did you know that your eyelashes can also start to look bare and sparse? There's no one cause for hair loss, but it can be blamed on genetics, stress and other medical conditions. If you've been relying on extensions, endless mascaras and expensive growth serums that leave you disappointed, there's hope! For Memorial Day, Amazon slashed the price of Bartslash Advanced Eyelash Growth Serum to $14. The affordable pick enhances hair growth and leaves your lashes fuller than ever.

The growth serum promises to thicken, lengthen and lift eyelashes. Bartslash's specially crafted formula helps to promote new growth and nourishes existing hairs so they appear bolder and more pronounced. The serum is apparently so effective that in a brand study, 95% of customers reported they saw eyelashes grow 50% in length in six weeks of using the product consistently.

The formula contains a polygonum multiflorum extract, which nourishes hair and adds luster and shine. The extract is packed with proteins and vitamins that are essential for healthy hair growth — think of it as a daily vitamin for your eyelashes. The natural and gentle ingredients make the serum suitable for all skin types.

Shoppers say it's the best bang for your buck.

One shared: "I absolutely love this stuff!! Has helped me save on expensive eyelash extensions every few weeks. This, paired with my fav mascara, works wonders!"

The serum delivers results in just weeks! "I tried a more expensive product before this one, it worked just a little bit. This product , for less than half, has already worked more in two weeks then the other one did in two months! Make sure you do it twice a day, it works great under mascara. Thank you for a great product!," a five-star reviewer mentioned.

"Amazing stuff....grab it now!" a serum user raved. "Ok so after a lot of trepidation, I thought ....why not? So I did. I bought one. Thinking to myself about another scam, but what the heck if it doesn't work I will just send it back. Well 4 weeks later and this 58-year-old woman with short, breaking eyelashes and patches where none grow at all now has luscious lashes. I use it twice a day but not all the time. I simply forget, so I might remember 3 or 4 times a week. But as you can see by the photo, my lashes look great."
