On average, they last up to 2 weeks, with some lucky few getting a good 3 weeks in!
Your shellac nails should remain shiny and chip-free for 14 to 21 days if you take care of them responsibly. Don't worry about your day to day activities: taking out keys, working on the computer and (light) cooking are no match for shellac.
Shellac was the first hybrid polish, produced by CND, and you can expect manicures to last about two weeks. Some may find that the chip-free finish lasts longer than this, but it's recommended that you get them removed after 14 days as by this time your own nail will have started to grow out.
Unfortunately, leaving your CND™ Shellac™ manicure on for too long can result in service breakdown; lifting, chipping, discolouration etc.
Even if you're not pulling the polish off, Dunne says that frequent Shellac manicures can take a toll on your nails. “During the removal process (especially if not done properly), you can risk removing layers of your natural nails and weakening the nails,” she explains.
If you just allow your gel nails to grow out, they can become weak and brittle as a result of being exposed to water and air, which could potentially damage your natural nails.
Step 1: Give Your Nails a Break
Most nail technicians suggest giving your nails at least a week-long break every eight weeks. Shellac, gel, dip dye, and acrylics require buffing the nails beforehand, and the harsh acetone for used removal compromises the top layer of the nail.
“For natural nails, a three- to four-week break usually will be sufficient to allow discoloration to fade, whether nails are yellow-orange or have white patches,” said Batra.
Gel manicures benefit those with weaker nails and lasts just that little bit longer than Shellac. However, the removal process is quite lengthy. Shellac is a thinner polish, so if you want to give your nails more space to “breathe' and have sturdy natural nail beds, this one's for you.
Over time, the bond between your nail and the polish starts to break down, causing the gel to lift away. And while we really do get how annoying it is, we urge you not to start picking or peeling.
Shellac is much less damaging to nails than traditional gels (or acrylics), and if your goal isn't to make your nails longer, then they're a great choice. Shellac looks like a thick glossy gel polish, and the main benefit is that it reduces chipping.
This is rule number one for shellac nails – DO NOT peel them off. Peeling off the shellac nails yourself can damage your natural nails by peeling off the stronger layers of your nails leaving the weaker nails exposed.
In our experience, SNS can last up to one week longer than Shellac nails without chipping, and SNS also creates a thicker-looking nail from all that powder getting added on. But we've found Shellac to be a little less damaging to our nails long-term than SNS nails.
After 1 week
Some nail types are very thin, weak, or oily. Thin and weak nails can't be buffed well enough to create the little “velcro” action that adheres the polish to the nail.
Because shellac nails use traditional nail polish, in addition to a gel layer, they're a little more prone to chipping than methods like the gel application, which means you may need touch-ups more than with other types of nails.
The Bottom Line. Shellac manicures are so convenient! They're chip-free, have zero dry time, and last up to three weeks. But both the application and removal process cause damage to your natural nails.
This is why heading to a professional to remove shellac nails is a good idea. A liquid solvent used to remove stubborn polish. Like traditional nail varnish remover, but seriously strong (I'm talking removing Sharpie strong). Cotton pads will be soaked in acetone, and wrapped around each nail, to dissolve the polish.
Adverse Reactions
Several cases of allergic contact dermatitis of the eyelids due to shellac in mascara, cheilitis due to shellac in lip products, allergic dermatitis due to shellac in a hairspray, and allergic dermatitis in black ink most likely containing shellac for tattooing have been reported.
CND™ SHELLAC™ Color Coat should be cured for one minute in the CND™ LED Lamp (preset button 2S) or two minutes in the CND™ UV Lamp.
“Lifting occurs when there isn't a correct bond between the product and the nail plate. Therefore, the best way to prevent lifting is through proper prep of the nail plate and product control. It's important to be very thorough when removing cuticle stuck to the nail plate—a quick swipe of the file isn't enough!
Since gel nail polish can be worn for weeks on end without even the tiniest chip, stretching the life of your manicure is tempting. However, Hadley suggests removing a gel manicure after two to three weeks maximum to avoid damaging nail beds and cuticles.
Gel polish lasts between 2-3 weeks at the minimum, while regular polish is lucky to go a week without chipping.
"Gel manicures could last up to two weeks with proper nail prep and at-home care, such as cuticle oil and hand lotion," says Duguay-Gordon. And if you're careful, they can last up to four weeks.
Soak a cotton pad in 100% pure acetone. Place the cotton pad around your finger and wrap aluminium foil around it, do this for each finger and allow to soak for 15 minutes. This step may need to be repeated a few times until all product is dissolved and able to be gently wiped or scraped off.
CND Shellac vs OPI GelColor Curing Speed
If you were using a LED lamp GelColor would have an edge over Shellac in speed and how well it cured the coating. But if it was in a UV lamp they both will cure at pretty much the same speed but Shellac would have an edge as it's formula will cure better then GelColor's formula.
