To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Really helps boast your nail growth and strengthens the existing nails. It's the perfect product for me because I have very long but brittle nails so it helps to have a strengthener. It does have a slight bluish color when applied to the nails but I don't mind that since it does such a wonderful job.
