Lesson 4 of 4 in this stage
Nails: growth, breakage and cuticle care
Understand where nails grow, distinguish growth from retained length, and learn useful daily care.
Locate the nail matrix that produces new nail, the nail plate and surrounding skin. Retaining length is different from accelerating growth.

The visible hard part is the nail plate, with the nail bed beneath it. Growth begins at the matrix near the base, not at the free edge you trim. An existing plate does not heal like a skin wound; damaged material must grow out and be trimmed. The cuticle helps protect the base, so cutting or pulling it away is not a consequence-free cosmetic step.
The matrix at the base produces growth; the nail plate is the visible structure. Caring for the plate protects growth already produced.

A nail can grow at the base while repeatedly breaking at the tip, leaving its visible length unchanged. Frequent wet work, detergents, abrasion and forceful gel or artificial-nail removal can weaken the plate. Oil or cream may improve flexibility and surrounding skin comfort without proving faster production at the matrix. Less breakage and faster growth are different claims.

A useful simple routine
Keep a manageable length, gently smooth snagging edges and moisturize nails and surrounding skin. Use suitable gloves for wet work and cleaning, and do not use nails as opening tools. Avoid peeling gel off or assuming supplements are necessary for every brittle nail. Pain, swelling, separation or a new dark band warrants medical assessment, particularly when one nail changes.
Know what each visible part does
The nail plate is the hard visible structure, the nail bed lies beneath it, and the matrix near the base contributes to forming new nail material. Surrounding skin helps protect the growing area. Aggressively cutting living cuticle tissue or scraping beneath nails with sharp tools can cause injury or inflammation.
What actually supports nail care?
Moisturize hands and nail edges, particularly after washing, and reduce repeated exposure to harsh detergents and prolonged wet work with suitable protection. Brittle nails do not automatically signal a vitamin deficiency; friction, chemical exposure and skin conditions can also matter. Pain, swelling or persistent unusual colour or shape changes call for medical assessment rather than cosmetic hardeners alone.
Your turn
Use what you learned
For the claim 'this oil makes nails grow faster', how do final length and breakage frequency differ?
See the answer and why
Final length may increase through less breakage. Faster growth requires tracking new growth under controlled conditions, not merely a photo of longer nails.
