14.2 Nail Repair
Key Takeaways
A crack in the enhancement, with an intact natural nail and no blood, is opened with a file so new product has a key, then rebuilt and reshaped.
A tear into the nail bed, the matrix, or living skin, or any bleeding repair, is stopped and referred; do not glue the wound, and check bleeding only under 49 Pa. Code § 7.94.
A small plate crack that has not reached the bed may be supported with a fabric wrap and a resin or thin overlay when the skin is intact; do not wrap fungus, green stain, or an open separation.
Glue is limited to a tip or a small non-living crack; it does not fix a lift or onycholysis, and a plate that cannot support length is shortened instead.
When only the enhancement is cracked
A crack in the enhancement product, with an intact natural nail and no blood, can be repaired. Open the crack with a file so new product has a key, a groove the fresh acrylic or gel can lock into. Then rebuild and reshape. Smearing product over an unopened crack leaves the seam underneath, and the crack returns. Pennsylvania does not publish a repair method. Keying the crack is standard nail-technology instruction.
The smile line is a frequent site. It is the curve where the free-edge color of the enhancement meets the color over the nail bed, and it flexes with every grab. A crack across that curve is still a product crack when the plate below is whole and the skin is unbroken.
When the injury reaches living tissue
A tear that reaches the nail bed, the matrix, or living skin is not a cosmetic glue job. The same stop applies to any repair that is bleeding. The matrix sits under the proximal nail fold and forms the plate. An injury there can change the nail that grows afterward. Stop. Check bleeding under 49 Pa. Code § 7.94, and only with powdered or liquid astringent on clean cotton or a clean towel. A styptic pencil is prohibited. Refer the client when the tear enters living tissue. Do not glue a wound closed. Glue would hold blood and debris on the open bed and would pretend the injury is a broken tip.
Supporting a short crack in the plate
A small crack in the natural plate that has not reached the bed may be supported if the surrounding skin is intact. A fabric wrap, such as silk or fiberglass, with a resin or a thin overlay, bridges the crack and spreads the stress. Do not wrap over fungus, a green stain, or an open separation. Covering them seals the problem in. If the skin is infected, refuse the service.
Uses and limits of adhesive
Glue is for a tip or a small non-living crack. It is not a substitute for removing a lift, and it is not a treatment for onycholysis. Onycholysis is separation of the plate from the nail bed. Gluing a separated plate down traps moisture, the same hazard as sealing a lift. Leave the separation open, remove loose enhancement, and refer if the skin is infected or the cause is beyond nail technology.
Strength after the patch
After a repair, rebalance the stress area so the patched spot is not the weak point. A lump over a crack collects the bend, and the nail breaks there again. Thin the old apex if it has grown forward, and rebuild the apex over the stress area. If the natural nail is too short or too damaged to support an extension, shorten the enhancement instead of adding length. Extra length on a broken plate increases leverage and pulls on the crack.
Home care matches a fill. Gloves for long wet work, no use of the nail as a tool, and a return before the extension becomes a lever. Oil the surrounding skin after the product is finished.
Salon duties while you repair
The room stays ventilated under § 7.91, because filing a crack and open liquid product still release dust and vapors. Under § 7.92, implements that touch the client are sanitized immediately after use and kept sanitary. If blood appears, stop and follow § 7.94 before any overlay. Do not finish the patch and check the bleeding afterward.
Cracked product across the smile line
A client cracked an acrylic enhancement across the smile line while opening a carton. The line runs through the product. The natural nail is intact, there is no blood, and the sidewalls and hyponychium are whole. Do not smear a bead over the closed crack, and do not call a drop of glue a repair. Open the crack with a file so new product has a key, rebuild, and reshape. Rebalance the stress area so the patch is not a lump. The plate can still support the existing length, so restore that length rather than adding more.
A split the client wants glued shut
Another client split the natural nail into the bed and wants it glued so the pieces will grow together. The tear reaches living tissue. Stop. If it is bleeding, check the bleeding only with powdered or liquid astringent on clean cotton or a clean towel, never with a styptic pencil. Do not glue the wound, and do not lay silk, resin, or an overlay on the open bed. Refer the client for medical care. Do not add length on that nail. An extension would lever the tear. A neighboring nail with only a small plate crack, intact skin, and no separation may still be supported with a fabric wrap and a resin or a thin overlay. The injured nail is not that case.
Matching the damage to the decision
| Situation | Repair decision |
|---|---|
| Crack in the enhancement only; natural nail intact; no blood | Open the crack with a file so new product has a key, then rebuild and reshape |
| Small plate crack that has not reached the bed; skin intact | Support it with a fabric wrap, such as silk or fiberglass, and a resin or a thin overlay |
| Lift, or plate separated from the bed | Do not glue the separation down; remove loose product and leave the pocket open |
| Green stain, fungus, or infected skin | Do not cover it with product or a wrap; refuse the service if the skin is infected |
| Tear into the bed, matrix, or living skin, or any bleeding repair | Stop, check bleeding under § 7.94, refer, and do not glue the wound |
An acrylic enhancement is cracked across the smile line. The natural nail underneath is intact, and there is no blood. How is that crack repaired?
Open the crack with a file so new product has a key, then rebuild and reshape.
Glue the crack shut and dismiss the client without rebuilding.
Treat the smile line as a matrix tear and glue it closed.
Smear fresh product over the unopened crack so the surface looks smooth.
A client split the natural nail into the bed. The split is bleeding, and the client wants the tear glued closed. What should you do?
Apply a styptic pencil to the split, then finish the overlay as booked.
Cover the open bed with a silk wrap, then add a long extension over it.
Stop, check the bleeding with astringent on clean cotton, and refer the client.
Glue the wound closed so the two pieces of plate can grow back together.
Which use of glue fits standard nail-technology practice?
Setting a tip, or securing a small crack with no living tissue.
Pressing an onycholytic plate back down onto the nail bed.
Closing a small bleeding tear of the nail bed after filing.
Sealing a green bacterial stain under a lifted enhancement.
