BL Lashes Black Diamond Lash Sealant for Eyelash Extensions | Overnighter Lash Sealer & Waterproof Coating for Retention & Aftercare (0.24 fl.oz, Black)

Works great for extensions

Great product, fast delivery 😊

I wanted to wait and use this product with a new set of lashes all the way till the next refill to get a good sense of how well it works, and if it's worth my money. My experience is that I didn't see any significant difference between the longevity of the extensions when I used the product verses when I didn't. The lashes lasted about the same time, however, I will still keep buying and using this sealant because I did notice that my lashes looked darker, and fuller. I cook a lot, I'm around heat and steam almost everyday, I also work 12 hr shifts where I'm on my feet a lot and I sweat, and I noticed that my extensions actually drooped, and looked a little weathered. This product lifted them and made them look new. I did notice that my lashes were maybe slightly harder after using but not uncomfortably at all, if I hadn't read about the hardening in other reviews I probably wouldn't haven't noticed it at all.

I don't usually have the time or motivation to leave a review, but I am so pleased with this product that I had to make the time. I pay a small fortune every two weeks to get my eyelashes extensions applied, but still by the end of the two weeks the ones on my right eye are almost always gone. I think it might have to do with the side I sleep on and rubbing my eyes inadvertently when I sleep. Two things have helped tremendously. First and foremost this sealant is working wonders. I'm only two days away from a touch up and I have most of my eyelashes, even on the right eye! Two, I wear a sleep mask now. No more rubbing my eyes while I sleep even if I want to! Finally, regarding the sealant, another issue I had with eyelash extensions was keeping them completely clean and neat, i.e. after a few days different eyelashes might start pointing in different directions, etc. This product is not only great for keeping my eyelashes on, but it's also great for grooming them to look like new.

Ok, I finally tried eyelash extensions for the holidays. I love the look but I don't like the upkeep. I purchased this black diamond coating and saw a huge difference from my first fill to my second fill. The first fill I waited 2.5 weeks before I had the fill and I was not using this product, now I am at 3.5 weeks and credit this product for my lashes still looking so great. I put it on in the morning and it straightens out my lashes very nicely. I let the product dry and then gently brush out the lashes with a dry lash brush. I don't know how long I will keep the eyelash extensions. I don't like the itchey feeling I get sometimes and I don't like it that I can't wash my whole face and use all the eye shadows I like to play around with. I think I'm going to TRY to find a eyelash serum that really works and will grow my own lashes! The trick is finding one that actually works!

I bought this stuff prior to vacation to keep my lash extensions up. While I think it may have helped some, I actually can’t be sure since they my lashes lasted the same amount of time without. Then you never know if they would have fallen out faster while on vacation had I not used it. I believe the price is definitely not worth the hype. The price for the amount of product is extremely marked up. Don’t be a sucker for false promises and over hyped advertising.

I am so disappointed in this eyelash coating. I have been getting eye lash extensions for over a year and usually go 2-3 weeks in between refills. Someone suggested I try a oil free for my lashes. All of the products my eye lash artist uses are Blink, I decided this coating was probably a great option. I read all the reviews and they were very mixed, but I thought I would give it a try. WORST MISTAKE EVER! I used it twice the first week. I didn't feel like it offered much of a change in the look, but decided to keep trying it. I noticed by day 7 after an eye lash fill, over half of my lashes had fallen out. This has NEVER happened to me. I went in for a fill that week thinking it was a fluke. I discussed the product with my eye lash artist and she was shocked as well. I decided to try again, using it only once during the week. After 5 days, my eye lashes were half gone again! I will NEVER use the coating again, NEVER! You would think the coating would be compatible with the Blink glue used with my extensions, instead it is like it breaks it down. This one little product has cost me $320 in early fills for my lashes. Do NOT buy this!!!

I bought this in hopes it would help my lash extensions to stay on longer and so far, so good. Before I used this, my lashes were staying on for about 2.5 weeks and were in need of a serious fill by then. I am now at the 2.5 week point and my extensions still look great! I've pushed my fill appointment out to next week, testing to see how long this really helps keep the extensions looking good.One thing I wasn't sure about when I purchased the item was if it was going to be a black coating or clear...it's clear. I really like how it goes on, making my lashes appear as though they are wet without looking like I overdid it with mascara. I don't use it every day, although I think some do. I typically use it every three days or so, when my lashes begin looking a little dull. This gives them the right amount of pick-me-up they need. I would definitely recommend it.
