The Nailgrowth Miracle Serum from Sally Hansen promises longer, stronger and instantly smoother cuticles. The serum is enriched with Biotin which is said to improve nail growth. I cannot claim that this product made my nails grow any faster, but it certainly improved their condition. The serum absorbs quickly, is non-greasy and provides your nails with a beautiful, refreshed look. My cuticles were softer, and my nails were less dry after applying the product. The serum has a thick consistency, and can be applied with a dropper and then massaged into the cuticles. The application process is simple, and mess-free. I would not recommend this product to someone who has nails that grow naturally fast, but if you’re looking for something to soothe dry/brittle nails, this might be the miracle product you’ve been waiting for.
