Initial Impressions and Goals
I decided to try Nutra Nail's 5-7 Day Growth Formula with the goal of strengthening my naturally weak and bendy nails. I've always loved nail art but my short, flimsy nails made it difficult. This product promised stronger nails, which was my primary concern.

I started using the formula about four months ago, applying it religiously twice a day for the first two months. I wanted to give it a fair chance before offering my review.

Application and Consistency
The formula itself has a pleasant consistency; it's not sticky or overly fragrant. Application is straightforward using the included brush. I typically apply a generous amount, ensuring coverage of the nail and surrounding cuticles.

I've tried using it with and without nail polish. I found it worked better without polish, allowing the formula to fully penetrate the nail bed.

Results and Observations
While the '5-7 day' claim is a bit ambitious, I did notice a significant improvement in nail strength. My nails became less bendy and less prone to breaking. The length increased, but this was more gradual than a dramatic, rapid growth spurt.

For optimal results, I recommend using it consistently for at least three weeks, applying twice daily. This longer-term use helps maximize the strengthening effects.
Final Verdict
Overall, the Nutra Nail 5-7 Day Growth Formula is a decent nail strengthener that delivers on its promise of healthier nails. While you won't see overnight miracles, consistent use does lead to noticeable improvements in nail strength and flexibility.

It's not a magic bullet for rapid nail growth, but it's a valuable tool for those who struggle with weak, brittle nails. I recommend this product to anyone seeking stronger, healthier nails, especially if used consistently for an extended period.
