Best supply store in Denver. The employees and owners are SO nice and helpful! Definitely going back everything Im in Denver!

David was very helpful. It’s my first time doing my own nails and with the little information I gave him he knew exactly what I needed. Definitely coming back!

This store has everything. To me it’s like candy land but for nail supplies. I always find everything I need here and definitely for a good price!

BEWARE . BEWARE . BEWARETHE NEW OWNER IS SO RUDE!HE SOLD ME DEFECTIVE PRODUCT AND REFUSED TO RETURN IT!I bought a foot scrub and left the store. When I got to the salon I opened it and the product was not pomegranate raspberry and it changed color. I called the store and immediately returned to the store 15 minutes later. The owner had the audacity to tell me I didnt buy the scrub there as I stood there with my receipt in hand. I explained the contents were faulty. He refused to investigate it, smell it or try to see what might have happened. Instead he insisted I tampered with his product and refused to return it.I CALLED THE PRODUCT COMPANY DIRECTLY and guess what? They confirmed the product was bottled incorrectly and that it changes color in sunlight!!!! I call Cosmo to explain my findings and told him he should apologize for accusing me of lying and tampering with his product. He hung up on me and refused to give me his email so I could forward the email from the company confirming the product was faulty. He is EXTREMELY UNETHICAL. My school, my students, my salons and my fellow nail techs have all decided to ban this store. He acted in a disgusting way and even though I prefer to shop local I will no longer go there. I am owed an apology. He has lost so much business over a $20 tub of foot scrub. Its a shame.

Very good customer service. So much variety. 100% whatever you need to look for they got!

Been going here for years- until today when I was chased down by an employee who forced hand sanitizer on me after I told them I’d just used mine in the car prior to coming in. It is not legal to force people to dump chemicals on their hands! I have extreme sensitivities to products and use only what my skin does not react to. I will resort to ordering files and other nail products from other suppliers from now on if the pro stores don’t have what I need. This place is nowhere close to friendly or professional like it was when Johnny was here.

Went in yesterday for a acrylic started kit really good price for what’s included! The guy who help me out was so helpful and nice (I believe his name was david.) Everything on the kit was great except the nail glue was dry i went back today and they exchanged it no questions asked. Also they have a hand you can practice with for $10 and its a great material. Definitely will be coming back for all my supplies

They have the line Kiara sky there and Morgan Taylor. Its like a nail warehouse!

Ive been here twice and i love it the supplies are so affordable and the products are amazing and the employees are so sweet! they need a raise!!

I been shopping here for years they recently changed ALOT!! Store looks great lots to choose from friendly staff.. Also received a free gift for my purchase. Cosmos is the spot! Guy at the counter was super nice and helpful.

David was very helpful and we had all that we needed

Love this place...great service and great prices...clean and organized...5 star!

I didnt remember where was the store n i found it and bought the massage oil that i was looking for my massages thank you.

I usually come with my friend and we were there yesterday around 5/6 pm and it wasn’t packed. The owner/workers are extremely nice and help you right away. I highly recommend this place they have a lot of stuff and the prices aren’t bad

Everyone was super friendly and helpful they had everything I was looking for and more! Lots of good products and you don’t need any cosmetology licensing to purchase! First time going here, I traveled all they way from Eastern Fort Morgan and I will be returning. I highly recommend. 👍🏼

I’m really disappointed of this store. I’m new in the nail business and decided to give these people a try. After the third time they somehow charged my card twice and I had to dispute it with my bank, what ever. Put it past me, I decided to go again to them, and each time I go I spend at least $200,, they gave me empty products:,( I had to drive back down there in which I don’t even live near the area. You’d think they would be extra apologetic but no, it seemed like they doubted me and made me feel so uncomfortable and awkward. They couldn’t even say sorry and when they did decide to give me something new they just put it in front of me and said here you go and walked away. That’s super rude....😢 LESSON LEARNED,, check your items in the store as soon as you buy it in front of their faces and check you bank account as soon as payment is processed.

Best selection of all things nails, great pricing and staff was very, friendly, knowledgeable and helpful. I also appreciated the steps taken for safety due to COVID-19.

My first time visiting the store seemed a little overwhelming because it’s packed with so much merchandise. Several employees asked if I needed help with anything. I had several questions regarding locations for specific items, prices, and even asked for a smaller quantity of a specific monomer. Staff were super helpful, and they even filled a 16 oz bottle of the monomer I was looking for so I didn’t have to purchase the full gallon! I live out of state, but will definitely come back next time I’m in town. Compared to the prices I’m used to paying out of state, I thought Cosmo had extra great deals on polishes and acrylic powders.

I really appreciate their customer service...and they always seem to have all my nail care needs!!

Great selection, service and pricing

The guy is extremely rude and unprofessional. The old owners are extremely nice and easy to work with, especially when you’re a regulars business owners and always bought products from them vs. these people.

Hi Guys, had to write a review on Cosmo. They have great customer service. Very helpful and informative. Answered all my questions and made great suggestions on product. A professional supply store thats open to the public. Yall should stop in and see their great prices too. i highly recommend Cosmo Beauty Supply. 😀

Hands down best supply house I have ever been in! They have everything you need to do nails plus more! Everyone is very knowledgeable and even more helpful! They always have the new shellac colors weeks before Salon Centric or state does!!! Also has a lot of really good brand names!! Will always shop here for all of my nails supply needs!!!! Thanks for being such a great business!

Are are so helpful I have questions and they always give me the answers. Great deals. And great products

This store has a HUGE selection! And everyone who works there are very helpful and so nice! Definitely will be back!

I love this place! The staff is extremely helpful (and funny)! Prices are so much better than Sally Beauty Supply and the selection is huge. They have a large supply of shellac colors.

New owner is so rude! I have been doing business with the old owner who was so nice. I spent $800 yesterday and I wanted to exchange the nail powder and they accused me of stealing $35 of nail powder because I didn’t have receipt. I didn’t have receipt for it it was 100 miles away from there. I have receipt and I will NEVER GO BACK TO THIS PLACE! They talked to me like I wasn’t a business owner but a thief off the streets. I even asked them to check their cameras and they would not even look!

Love this place! I always come here to get my dipping powder! They also have a lot of varieties of nail polish. Arcylic and many more! Price is cheap compared to other places. Highly recommended!

I am always Beyond pleased when I get to stop into my favorite nail supply store! Staff is always very friendly, the shelves are clean organized, well stocked and the prices are ridiculously inexpensive! Cosmo nail and beauty is the only place I go for my nail supplies!

Great experience . Clean and great price

Didnt have much for nails😞. But wonderful customer service

Oh my, this place is a nail supply shop open to the public with a massive selection of items. Polishes: there are so many colors and the prices here are low. Really low - better than what you typically find online. They carry Orly, Essie, China Glaze and more with gel polishes including CND & Gelish. And chrome powders!Walking through the store, I can see that if you wanted to set up a salon, this place would carry just about everything you would need, including furniture.The staff is super friendly and happy to help, answering any questions and making suggestions. I only wish they had more in the realm of nail art which is the only area that this place is lacking - stamping plates or vinyls would be nice but even so, Ill make the hour long drive any time I need to add more colors to my collection.

Great customer service. And they had everything that I needed and more. I love this place.

If you need polish this is the place to go. Gel, regular, dip. Great place.

They are nice and helpful

It was verry good ...thanks you all where verry help thanks

Like going there it has everything and is not that expensive...

Very friendly, knowledgeable and helpful! They also have just about everything nail wise! Definitely making this one of my regular stops!

A manicurists dream. The staff is so helpful and friendly and they actually stock for us nail techs!

If you are a nail technician this is your place to shop. Great prices.

Selection is very limited. Not sure if it’s because I’m from Houston where there’s so many options but I was not impressed.

Johnny and his brother are super helpful, knowledgeable and hilarious!

Great customer service and great place to find nail supplies
