This brand has the best products for lash and hair growth, so happy I found it through my friend💗

Serum is not working. I order together with my friend. After few months we had barely visible result. 1mm longer? Please. Not for this money. Nanolash will be my number one. Higly recommend.

Fantastic serum, made my lashes so much longer and thick! Would recommend over Grande any day

I loved the eyelash growth serum it actually works! And the package came fast.

I’ve been using Sins’N Lashes lash serum for over a year now every night before I go to bed, and it grows my eyelashes like crazy! I also started taking biotin pills while using it and it has boosted my lash growth as well! Highly recommend this product! Also, I get compliments on my lashes all the time especially when I have mascara on, but even when I use clear mascara they are still very long!

it was really perfect serom, did worked well with me and I loved it.

This was second time ordering the sins and lashes serum and I did not receive it. I contacted sins and lashes customer service through email and they told me to wait for a month because the investigation takes longer. I stayed patient and waited for more than a month just for sins and lashes to tell me that they think my package was delivered and they won’t refund or reship me. I have never had such a bad experience. I will making a brief tiktok about this matter shortly. Do not buy from them or you will end up losing your money and getting scammed like me! :)

I just want to say thank you to Sinslashes Customer service. I was not able to pick up my order on time and it went back to Germany. Isabelle from Customer service was so kind and always returning my mails to give me information about my parcel and assuring me that they were going to return it as soon as they get it. That's what happened and they did their best to resend it as soon as it reached them. So if we are looking at the way they handle customer service I can only recommend them.

I’ve been using it with castos oil and it did magic

I never received my package, I’ve been mailing since 2 weeks and they haven’t answered any of my mails, it’s impossible to contact the company. I just want my money back. They are active on social media but they’re not working in customer service area, this company sucks.

Subject: Urgent: Refund Request for Undelivered Order

Dear SinsLashes team,

I placed an order which was supposedly shipped via DHL from Germany to my address in central Barcelona (Plaza Catalunya). Despite my address being perfectly valid and well-known, the package was never delivered. I was informed that DHL “couldn’t find the address,” which is clearly an error.

I emailed you two weeks ago with no resolution, and I am now formally requesting a full refund for the undelivered order. I have been patient, but the lack of response is unacceptable.

Please confirm my refund within 48 hours, or I will be forced to take further action through:
• Filing a complaint with the European Consumer Centre (ECC Spain)
• Reporting the issue to DHL and local consumer protection agencies
• Initiating a chargeback through my bank or credit card company

I expect this to be resolved immediately.

I ordered the Dream Hair Bundle, Eyelash Serum Duo, and Vanity Bag — but when my package arrived, the hair products had completely leaked, one of the serums was missing, and the vanity bag wasn’t even included.

I emailed customer service straight away with everything explained and even followed up again after getting no reply. Still nothing.

At this point, I just want a full refund for the missing and damaged items. The lack of communication is honestly unacceptable. I was excited to try this brand after seeing it on TikTok, but this has been such a letdown. Definitely not the experience I expected.

Scam! I waited it for it to deliver for almost a month and when it finally delivered I was extremely disappointed it’s emptyyyyy!! Why do such a thing it costs me a lot!!

I was impressed by all the great reviews for this serum but the truth is their customer service is non-existent. I never received my package and I sent proof of this to their customer service team and have not responded or even acknowledged my email. Very poor!

i’ve ordered this lash serum back in july and i’ve tried one more after this one but it doesn’t compare at all. very good lash serum

Product has ran out after 1 week.

Do not buy from this store; it’s a scam. I didn’t even receive a confirmation email and tried to contact them without any response.”

Great results, my lashes are so full and long

I loved the product and the results! I just wish they followed through with the free serum for a review coupon they gave me

I loved it and I'm planning on reordering a new set of 3 serums 🥰🥰
