How Do I Strengthen My Brittle Nails?

If you get gel manicures, acrylics, or any other type of nail enhancements on the regular, there’s a good chance that your natural nails aren’t as strong as they once were. It’s kind of a vicious cycle: The nail enhancements may damage your nails, but they can also help prevent your natural nails from breaking. A fresh mani is only a temporary solution, though, and eventually, you’ll need to give your natural nails some TLC to get them back into shape. 

According to board-certified dermatologist Dr. Claire Wolinsky, M.D., nail-strengthening polishes can be a helpful solution if you’re dealing with weak, brittle, or damaged nails. “Some strengtheners contain vitamins like biotin that can strengthen the nail plate,” she explains, while others “contain keratin binders to fortify the nail plate and prevent damage.” Both work, but the former tends to be a bit easier to find. (If you need a recommendation, we’re fans of the OPI Nail Envy Original Nail Strengthener, which contains biotin, calcium, and vitamins A, C, and E). It’s important to note that you’ll want to use your chosen treatment continuously — and apply it to bare nails — in order to see lasting results. 

If you can’t give up your gel nail habit though, try switching to builder gel, or a structured gel manicure. GelBottle Builder In A Bottle — or BIAB — is a thicker, stronger gel that contains nail-strengthening ingredients. The formula is stronger and more flexible than regular gel so it’s less prone to chipping and/or breaking.

Your manicure habit may not be the only reason your nails are brittle, though. Frequently washing your hands or using hand sanitizer can dry out your skin and weaken your nails, Dr. Wolinsky says — even if it’s been months since you last hit the salon. To further protect your nails, she recommends moisturizing regularly, especially if you wash your hands often. Your nails can also become weaker with age, as your body’s production of keratin (the protein that your nails are made from) diminishes over time. And, Dr. Wolinsky notes, there are certain medical conditions — including thyroid disease and psoriasis — that can cause your nails to weaken. If you’re unsure why your nails are brittle, or if at-home remedies aren’t proving helpful, it may be a good idea to contact your doctor or dermatologist.
