As a beauty salon owner with over 14 years of experience in the beauty industry, I am considered an expert in this field. With a deep passion for the industry, I have witnessed firsthand how eyelash extensions can enhance one's confidence and beauty. However, the damage that traditional salon lash extensions can cause to natural lashes is alarming. Based on my extensive knowledge and experience, I created Underlash™ - a safer alternative to traditional lash extensions. Our lashes have undergone rigorous testing and have been well-received by our clients. With Underlash™, you can achieve the beautiful, confident look you desire without compromising the health of your natural lashes.

I'll admit I was skeptical about these lashes lasting for up to a week - but they did! I got 6 days out of mine. The Kit has everything you need in one, especially the very useful applicator tool to both apply and press them on with the special, long lasting glue. Instead of sitting on top of the lashes, they glue on underneath and look so natural. Defiantly worth the splurge!

I was first introduced to Underlash while working on a shoot for the brand, I was amazed at how easy they were to apply and how natural they looked, I’ve never been a fan of eyelash extensions on my clients as they can look too fake. Underlash lashes enhance the clients eye’s without over powering, I always recommend underlash to my brides who want longer lasting lashes for their celebrations over extensions every time, there is no comparison. There is no damage to the natural lash either which is another reason i love them so much!

worth the effort !

I've been using the natural lashes in brown for a few months now and have had a bumpy ride with them, it took a while to figure out how much of the glue and seal I needed to have them stay put but also not look visibly "gluey". Once I figured it out its been much easier ! They are quick to apply once you've had practice, you just need patience to get through the "trial and error" stage.
A warning to those with hay fever or watery eyes - because they can't get wet for 48 hours having watery eyes from allergies etc. can make it a little annoying as it can mess with the bond !
All in all I definitely intend on continuing to use them for the foreseeable future <3

Once you start you cant stop

I have always been a serial last girl, however with the cost of living, i could no longer afford the upkeep of getting them done by a professional. I saw underlash come up on instgram and thought it was such a good idea, and cost effective. Ive used them for almost a year. There amazing. Quick to do and i can get 2 weeks out of mine.
I have now gotten my sister and work friends onto them.

The best lashes

I love how these lashes are so light and customisable being in a strip that you can cut, instead of segments. I did initially have some trouble with white flaky bits and them being stiff but I contacted Underlash and they gave me such helpful advice and even sent me a free lash serum. The customer service was so great! It turned out I was using too much of the sealer which was causing the buildup. Absolutely love these lashes and will definitely continue using them!
