butter LONDON Horse Power Base Coat Nail Polish – Clear Strengthening Treatment with Biotin & Horsetail Extract

butter LONDON Horse Power Base Coat is a restorative nail primer formulated with horsetail extract, biotin, vitamin B and calcium to strengthen, protect and help revive damaged, fragile nails.

Whether your nails have suffered from chipping, peeling, frequent polish wear or general weakness, this treatment acts as a prepping and repair step before color. The clear basecoat is lightweight, quick-drying and designed to create an even foundation that reduces staining and supports healthier-looking growth. It combines botanically inspired ingredients with fortifying vitamins to support nail resilience without harsh additives; the formula is cruelty-free and gluten-free.

How does Horse Power help heal and strengthen weak nails?

The ingredients in Horse Power target common causes of brittleness and splitting. Horsetail extract provides silica-like support for surface texture while biotin and vitamin B contribute to a more resilient nail matrix, and calcium helps reduce breakage.

• Horsetail extract: supports nail surface structure and smoothness
• Biotin: nutrient that assists in promoting stronger nails
• Vitamin B: helps nourish and revitalize fragile nail plates
• Calcium: reinforces nails to resist chipping and splitting

How should I apply this basecoat for best results?

Start with clean, dry nails free of oils and residues for optimal adhesion. Apply one even coat of the basecoat, allow it to dry fully, then follow with your chosen nail polish; for treatment-focused results, wear the basecoat alone between manicures.

• Clean nails with polish remover or soap and water
• Apply a single thin, even coat and let it dry completely
• Use under polish as a primer or solo as a strengthening layer
• Repeat every manicure or nightly during repair cycles

Will Horse Power prevent nail staining from colored polishes?

Yes — this basecoat creates a clear barrier that reduces pigment transfer from bold or dark nail lacquers. Applied correctly it helps preserve the natural tone of the nail and extends polish wear by improving adhesion.

• Acts as a protective primer under color polishes
• Minimizes yellowing and staining from intense pigments
• Improves polish longevity and prevents premature chipping
• Suitable for frequent polish users who want to protect nails

Is this formula safe for people with sensitivities?

butter LONDON formulates with cleaner ingredient choices and excludes common harsh toxins, and this basecoat is gluten-free and cruelty-free. As with any cosmetic, patch testing is recommended for highly sensitive individuals.

• Gluten-free and cruelty-free formulation
• Free from many common harsh chemicals used in traditional polishes
• Patch-test before regular use if you have very reactive skin
• Non-staining clear finish suitable for most nail types

Who is this for: butter LONDON Horse Power is ideal for anyone wanting to revive brittle, peeling or easily broken nails, polish lovers who need a protective primer, and users seeking a cleaner-strengthening treatment without animal testing. It suits daily polish routines and periodic repair programs—especially useful for those rebuilding nail strength after damage or frequent color changes.
