Hard gel polish is another type of builder gel. It can be sculpted and shaped to artificially lengthen your nail. It’s not the same as regular gel polish (which is much softer) as regular gel doesn’t cure hard enough to extend nails.
Because hard gel polish is a type of builder gel, it too can be used alongside other gel polishes. Most forms of hard gel polish are hypoallergenic, which is a huge bonus for those with sensitive skin. Acrylic nail extensions can achieve a similar look, but contain more allergens, which is why hard gel is so popular.

Another issue with acrylics is they can cause more damage to your natural nails than gel manicures. Hard gel is more flexible and durable than acrylics. Acrylics use more solvents in their formula, which can be drying to the natural nail, causing it to weaken. This can mean when the acrylic extensions are removed, the health of the nail is worse than before the manicure.

With hard gel, the application is different, and it allows the nail to be better nourished and protected. Gel is flexible, which increases their resilience. Acrylic nails are rigid, which means any movement can damage the nail plate by creating small cracks and chips.
