Herôme Nail Hardener Extra Strong 10 ml

Caution: Consumers with thin, weak nails should always be advised to use the strong nail hardener first. The extra strong nail hardener should only be used if this fails to improve nail hardness. The extra strong nail hardener must be used on one nail for several days to test compatibility prior to regular use. The extra strong nail hardener should not be used immediately after removing false nails. Herôme Nail Hardener Extra Strong is designed for particularly soft, thin nails that split easily. It guarantees long, hard nails after being applied for 2 weeks.
