I have been having eyelash extensions for 20 years.. long before it became really fashionable. I would not have them done without using black diamond. I’ve used it for many years now. It just makes them last longer without a doubt. False economy not to use it.
So I tried this in high hopes after viewing the reviews, but after trying this out myself a few times, I saw no difference in retention whatsoever! Big shame ): didn’t irritate my eyes at least
So sorry to hear the sealant didn't work out for you. Please contact us at help@mylashstore.com.au and we'll be happy to try and work something out for you.
No. Don’t buy.
Hi Lisa,
So sorry to hear the diamond coating sealant wasn't to your liking. Our customer support team will be in touch to see if there's anything we can do for you.
This is the number #1 thing that has helped me go longer between infills. As i have an oily skin type it's always a struggle to keep lashes on. However this product allowed me to go from fills every 2 weeks to every 3 weeks / 3 & half at times ! Even my lash tech was surprised at how well they held up. I apply daily, start the day you get your lashes done and they won't budge. Less is more as U only need a light layer, if too much is applied lashes can clump and stick together.
Not sure if it’s helping keep my lashes more than normal
Been looking for a while for a sealant that gives my extensions the support without making them look and feel like cardboard. Very natural look and no clumping . Will be buying again
Really love this product as it helps with glue retention. Would recommend to any lash artist.
👍
Get it!
I only bought 1 to try out.
I gave this to my sister and her lashes outlasted my other clients who don't have it.
I would like to see this product in a smaller bottle for affordability.
This sealant has quickly become my salons best selling product! Overtook cleansers, growth serums and even spoolies. Well worth it and clients love the results.
