Keratin Booster

Keratin Booster by ProNails is an intensive keratin serum that absorbs instantly into the nail plate to restore strength to damaged, brittle nails. It needs no drying time and leaves no residue, so it's easy to reapply several times a day.

It targets the cause of layered breakage, dryness and loss of elasticity, so the nail bends instead of splitting. With daily use, improved strength is noticeable in three to four weeks. It's suitable for all nail types, even very damaged ones.

Benefits

• Restores strength to the nail.
• Helps prevent breakage and nails that peel into layers.
• Restores hydration and elasticity.
• Instant absorption, no residue.

Key ingredients

• Hydrolyzed keratin: replenishes the protein the nail is made of.
• Panthenol and allantoin: restore hydration and elasticity.
• Biotin and hydrolyzed silk: help create a smoother, stronger nail.

How to use

On clean, dry nails, apply the serum with the brush from the free edge towards the cuticle to cover the whole nail plate. Use it several times a day; it absorbs instantly. On very damaged or brittle nails, keep up the daily routine for at least three to four weeks before assessing the result.
