What Chemicals Harden Nails?

Formaldehyde

• Keratin owes its strength to its structure, which is a system of cross-links and protein strands. Formaldehyde works by adding additional cross-links to the nail plate by chemically reacting with the existing protein, and bonding with it. Excessive use of formaldehyde will cause brittleness and in some cases, an allergic reaction.

DMU

• Dimethyl urea works in a very similar way; however, unlike formaldehyde DMU hardens the nail plate without causing brittleness and it is an unlikely irritant. DMU is able to strengthen the nail bed without excessive cross-linking, meaning the nails have a balance of toughness and solidity.

Gelatin

• This is a popular ingredient in nail-hardening products even though scientists discredit its benefits. It does, however, work as a very effective shield to protect the nail while it is naturally growing itself and becoming healthy. This in turn means that the nail has an opportunity to naturally build strength and harden.

Vitamins

• You can increase the performance, strength and resilience of any part of the body, by simply maintaining a healthy diet with a decent intake of vitamins. Ensuring that you consume enough vitamins and minerals, your nails will continue to sustain natural strength.
