Lesson 4: Onycholysis Nails

In this lesson…

Onycholysis Nails

Onycholysis is the painless separation of the nail plate from the nail bed, typically starting at the tip or sides and progressing backward, creating a white or yellowish discoloration. Common causes include trauma (excessive manicuring, injury), fungal infections, psoriasis, thyroid disorders, or reactions to nail products.

Signs:

• Visible separation of the nail from the bed

• Discoloration (white/yellow due to trapped air or debris)

• Possible thickening or brittleness if fungal infection is present

Treatment:

1. Trim nails short to prevent further lifting.

2. Avoid trauma (aggressive manicures, picking) and irritants (harsh chemicals, acrylics).

3. Treat underlying causes:

   • Antifungals (for fungal infections)

   • Thyroid or psoriasis management (if systemic)

4. Keep nails dry and wear gloves during wet work.

Note: Full recovery takes months as the nail regrows. Consult a dermatologist if separation persists or worsens.
