Recently, my nails have been in a serious need of TLC! They were brittle, breaking constantly, and frustratingly short. With the holiday season around the corner, I decided to try the Leighton Denny Nail Rebirth Intensive Repair Capsules to see if they could work their magic. Spoiler alert: they didn’t disappoint!

The Results

I’ve been using this treatment for a few weeks and my nails feel thicker, have grown longer and have been less prone to breakage. I’ve been very happy with the results!

Here’s a before an after using this treatment for a few weeks:

Not only has this treatment delivered noticeable results, but it’s also a joy to use. The subtle, pleasant scent makes it a relaxing part of my nighttime routine, and I’ve been looking forward to this little act of self-care when I get into bed.

How to Use

It’s simple:

  1. Twist off the top of the capsule.
  2. Squeeze the formula onto clean, polish-free nails.
  3. Massage it in.

You can use one capsule daily for 14 days for an intensive repair, or apply it as needed for a quick treatment boost.

Key Ingredients

NAIL REBIRTH vegan capsules are formulated with Neonyca®, extracted from celery seed, and scientifically proven to help hydrate and strengthen, bring the natural nail back to life, and restore and maintain the natural beauty of a great nail.

Additionally, a blend of Jojoba and Sweet Almond Oil helps to hydrate and condition the nail bed.

It has a 99% plant-based formula.

I love the capsule format. It ensures the formula stays fresh and mess-free. Each capsule contains enough to treat both your fingernails and toenails, but I found one capsule was enough to use across two treatments.

Ethics Check

  • Leighton Denny states that its formulas are cruelty-free (not tested on animals) and many, including Nail Rebirth, are vegan-friendly and largely plant-based.
  • The capsules are veggie-derived and free from several traditional nail-care toxins.
  • While the brand promotes clean, plant-focused formulas, it does not prominently display third-party cruelty-free certification or detailed sustainability reporting, so those seeking independently verified credentials may wish to contact the brand directly.

If your nails are crying out for some love, the Leighton Denny Nail Rebirth Intensive Repair Capsules might just be the miracle they need. Healthy, stronger nails? Yes, please!
