Spoon-shaped nails (koilonychia) · Splinter haemorrhages (thin dark vertical lines under the nail) · Clubbing (enlargement of fingertips with distinctly curved nails) · Unexplained dark streaks or discolouration under the nail plate · Painful separation of the nail from the nail bed (onycholysis)
Consult a general practitioner if nail brittleness is accompanied by unexplained fatigue, hair loss, weight changes, or if your nails become thick, painful, severely discoloured, or detach from the nail bed.

Iron and Protein Rich Nutrition
What it is
Provides amino acid building blocks and oxygenates the nail matrix for healthy growth.
Why it might help
Keratin synthesis depends on sulfur-rich amino acids (cysteine) and adequate microvascular oxygen supply supported by haemoglobin.

Topical Urea Cream (5-10%)
What it is
Acts as a potent humectant that binds water into hyperkeratotic and brittle nail structures.
Why it might help
Low-dose topical urea improves nail plate hydration and flexibility by binding water inside keratin complexes.

Choline-Stabilised Orthosilicic Acid
What it is
A bioavailable form of silicon that supports structural nail integrity by facilitating collagen cross-linking within the nail plate. Seek medical evaluation if brittleness is accompanied by hair loss, cold intolerance, or unexplained fatigue.
Why it might help
Clinical trials suggest oral silicon supplementation improves nail roughness and reduces brittleness over twenty weeks of continuous use.

Horsetail Leaf Infusion Soak
What it is
Horsetail (Equisetum arvense) is naturally rich in mineral silica and flavonoids, providing a nutrient-dense botanical bath to strengthen frail nail beds.
Why it might help
Traditional herbal use highlights mineral absorption through cutaneous application, though robust clinical data on topical horsetail remains limited.

Acetone-Free Solvent and Glass Buffer Routine
What it is
Removing harsh drying solvents and replacing metal files with fine-grit glass files minimises mechanical trauma and lipid stripping from the nail keratin matrix.
Why it might help
Acetone significantly strips natural nail lipids and water content, exacerbating onychochizia. Glass files produce smoother keratin edges than metal or coarse emery boards.

Warm Paraffin Wax Bath
What it is
Deep heat therapy combined with occlusive wax seals moisture deep into the nail matrix and cuticle layers while promoting capillary perfusion.
Why it might help
Thermal occlusion enhances skin barrier hydration and temporarily increases localized blood flow to periungual tissues.
