Nutrient gaps
This is the big one.
-
Iron deficiency → brittle, thin, or spoon-shaped nails
-
Biotin (B7) → peeling and splitting
-
Protein → weak, slow-growing nails
-
Zinc → white spots, fragile texture
If your nails look sad and you’re tired or getting sick a lot, that combo matters.
Dehydration (yes, really)
Nails need moisture just like skin. Not drinking enough water—or overdoing caffeine/alcohol—can make nails dry and prone to splitting.
Too much water + chemicals
Ironically, constant soaking weakens nails:
-
Frequent hand-washing
-
Dishwashing without gloves
-
Acetone nail polish remover
-
Gel/acrylic manicures back-to-back
Nails swell in water, then shrink when dry → micro-cracks → break city.
Thyroid issues
-
Hypothyroidism can cause brittle, slow-growing nails
If nail problems come with hair thinning, feeling cold, or low energy, it’s worth checking.
Aging + hormones
As estrogen drops (especially during perimenopause/menopause), nails often become drier and more fragile. Totally normal, annoyingly real.
Stress + overuse
Chronic stress messes with nutrient absorption and growth cycles. Add nail biting, picking, or using nails as tools (we’ve all done it), and… snap.
What actually helps
-
Eat protein at every meal
-
Iron-rich foods (or supplements only if needed)
-
Biotin (small doses, not megadoses)
-
Cuticle oil daily (non-negotiable)
-
Gloves for cleaning
-
Take breaks from gels/acrylics
If you want, tell me what your nails look like (peeling layers, vertical ridges, soft bends, sudden breaks), and I’ll narrow it down way more precisely 💅
