Product description

For Nails That Are Solid as a Rock Deborah Lippmann, manicurist to the stars, started out as a songstress and, as a result, many of her nail products are named after major pop icons, and other pop culture songs and figures. Make wimpy, thin nails both stronger and longer with Hard Rock Hydrating Nail Hardener and Base Coat. Especially Suited For: All skin types. Before adding a pop of color, try Deborah Lippmann Hard Rock Hydrating Nail Hardener and Base Coat. If applied daily, it will help weak nails grow naturally, because of the inclusion of Aucoumea Klaineana extract, a natural resin from west African trees in the formula. Aucoumea also helps to strengthen nails, and prevents ridges for smoother, healthier nail growth. This nail hardener also contains protein-building biotin (a cell regenerator) for strengthening, and hydrolyzed soy protein for hydration, to keep your nails strong yet pliable. For Best Effect: Apply a light, single coat, and add one coat on top of another daily for a week. Then remove and begin again. If you have just removed artificial nails of any kind, you may also use Hard Rock daily. Start with it as a base coat, add two coats of color, and finish with Hard Rock as a top coat, while re-growing nails. Then, after about three months, just use it once or twice each week to keep nails strong and beautiful.

Celebrity manicurist Deborah Lippmann, luxurious hand & foot care treatments. In 2018, Allure magazine awarded Deborah Lippmann winner of the best nail polish formula.

User questions & answers

Question:	Cruelty free
Answer:	Teslas and iPhones are also made in China. It all depends on whether the designer is trying to make it on the cheap or not.
Question:	Can I use this under nail polish
Answer:	Sharper than normal pair of clippers. So it clips through your nails like butter (instead of sometimes bending), your nails have cleaner edges so it doesn't peel, and it lasts longer - sometimes cheaper pairs will fall apart after not so long.
Question:	Once applied, does leave a shine
Answer:	I just checked amazon.com. You may buy a wire cutter for about $5.00. Why on earth would you use a $20 NAIL CLIPPER to "cut though 22 Gauge wire"?
Question:	Where can i buy the original nail optimizer made by olan laboratories
Answer:	Sharp blades and other tools are made using AUS-34 stainless steel, but even the highest quality stainless steel is not completely rustproof. It’s best to dry them after use.
