Shellac is a blend of gel and nail polish. Because it is like a polish, it can't be used to extend your nail. Because it is like a gel, however, it does add strength and durability. In the long term Shellac is much less damaging to nails than traditional Gels (or Acrylics).
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 simple answer is your nails are dry causing peeling and brittle nails. Shellac cannot damage or weaken your nails once applied and removed correctly.
Shellac is thinner and softer than gel polish, but harder than traditional varnish.
Although gel manicures can be beautiful and long-lasting, they can be tough on nails. Gel manicures can cause nail brittleness, peeling and cracking, and repeated use can increase the risk for skin cancer and premature skin aging on the hands.
The gel dehydrates your nails, making them dry and fragile, so you want to apply moisturiser or oil on your cuticles and nails. Often! Keeping the cuticle nourished and supple helps a new and healthy nail to grow, so focus most of your attention on that area.
If you're one of them, these tips from dermatologists can help you reduce the damage: Choose soak-off gel nails instead of acrylic nails. While gel nails can cause nail brittleness, peeling, and cracking, they're more flexible than acrylic nails. This means your own nails are less likely to crack.
Who Shouldn't Use Shellac Polish? If you have brittle or thin nails to begin with, you might want to take some steps to improve your nail health before trying shellac (or any gel manicure), as getting shellac can cause further damage if the manicure is applied to already damaged nails.
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.
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.
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.
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.
Unfortunately, leaving your CND™ Shellac™ manicure on for too long can result in service breakdown; lifting, chipping, discolouration etc.
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.
The bottom line
If you're trying to switch up your manicure, shellac nails are definitely worth a try. They're long-lasting, cute, and easy, and as long as you get them removed properly, they won't cause any major damage.
Another reason the SNS procedure tends to weaken nails is the removal process. This is an inflexible product, so any breaks or lifting usually takes your own nail with it! People prone to picking or removing can also peel away layers of their own nails with the product.
They are worried about the possible harmful effects of UV light exposure." Additionally, while Shellac appears to help avoid the damage to the nails caused by acrylics, SNS goes a step further, according to Vo. “SNS is positively good for nail health.
The Down-Low on SNS
Unlike your typical lacquer or gel polish, SNS is applied as a powder in multiple coats that hardens onto the nail. Where Gel nails rely on a UV lamp to set the polish in place, SNS eliminates the need for unnecessary exposure, causing people to think of it as a healthier alternative.
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.
Keeping your skin moisturised will extend the life of your shellac nails and keep your hands looking healthy and youthful. Use hand cream during the day (reapply as often as needed) and a richer cuticle oil at night before bed. The oil will treat your fingers overnight and keep nails from flaking for lack of moisture.
A basic manicure, with the right polishes, is the healthiest for your nails. When we say the 'right polishes' we mean the best nail growth polish or breathable nail polish. The harsh chemicals in many polishes often degrade our nails. Using an organic polish that contains vitamins, is the best way to avoid damage.
There is very little evidence that SNS is any better or worse for your nails than gel polish, hard gel or acrylic. What causes damage to your natural nails is not the product itself, but the application and removal process. This is why your technician will advise you not to pick at or peel off your gel or acrylic.
You might hear people use Shellac as a generic term for gel polish because it's the original, patented product, but Shellac is a product only offered by CND. Arnold says unlike traditional gels that are difficult to release from the nail, Shellac removes with no nail damage and no downtime needed between applications.
