Treatments for splitting nails begin with regular maintenance and protecting them from harsh chemicals. Individuals who are plagued by splitting nails should consider beginning a regimen of thoughtful prevention paired with restorative techniques, according to Mayo Clinic. Ongoing nail hygiene may improve nail strength and curb splitting.
Good nail care includes regularly trimming the nails and shaping rounded tips. Nails also need moisturizers and may benefit from hand cream that is carefully massaged into the nails and cuticles. A weekly application of nail hardener may help protect the splitting nails, advises Mayo Clinic. Biotin is a nutritional supplement that research suggests may help repair and strengthen nails.
