Sally Hansen Nailgrowth Miracle Clear Nail Serum — Nail Strengthener with Biotin & Peptides, Fast‑Absorbing Protection

Sally Hansen Nailgrowth Miracle® is a clear nail serum that uses concentrated peptides and biotin to strengthen nails, protect them from breakage, and support visibly longer growth in days.

Formulated for brittle or slow-growing nails, this treatment combines advanced peptide technology with biotin to nourish the nail plate and condition cuticles. The lightweight, clear formula can be worn alone or under polish, absorbing quickly without stickiness. In consumer testing, nails measured noticeably longer in two weeks when used as directed.

How does this serum help nails grow faster and resist damage?

The Nailgrowth Miracle® serum targets the nail matrix with concentrated peptides that support structural integrity while biotin helps improve nail resilience. Together they reduce splitting and chipping, allowing nails to grow out healthier and appear longer over time.

• Peptide-rich formula supports natural nail structure
• Biotin helps promote stronger, less brittle nails
• Fast-absorbing, non-greasy texture so nails can grow uninterrupted

What results can I expect and how soon will I see them?

Visible improvement in nail length and condition can appear within a couple of weeks; consumer measurements showed up to 59% longer nails at two weeks in a fixed-point study. Individual results vary by starting nail health and consistent use.

• Noticeable smoothing of nail surface and cuticles after first applications
• Measurable length gains reported in two-week testing
• Best results with daily application and proper nail care

How do I use this nail treatment and can it go under polish?

Apply a thin coat to clean, dry nails and surrounding cuticle area once daily or as directed. The clear finish dries quickly and is suitable as a base under nail polish or on bare nails for a natural look.

• Use on one or both hands, focusing on the base and free edge
• Layer under color or wear alone for a glossy, protective coat
• Reapply after removal or as part of a daily nail-care routine

Are there any texture or cosmetic benefits besides strength?

Yes — the serum softens and smooths cuticles while improving the nail surface for a neater, healthier appearance. Its clear formulation provides shine without altering polish color or finish.

• Instantly softens cuticles for easier grooming
• Improves nail surface texture and sheen
• Clear, non-yellowing formula compatible with other nail products

Who is this for: Sally Hansen Nailgrowth Miracle® is ideal for anyone with weak, brittle, or slow-growing nails who wants a straightforward, science-forward treatment. It’s suitable for polish wearers and those who prefer natural nails — especially helpful for people who regularly experience splitting or chipping and want to support healthier, longer growth without thick or oily products.
