If you’ve ever longed for longer, stronger nails but found that they grow slowly or split and peel easily, you may have wondered whether nail growth serums can help. We’ll take an in-depth look at whether these specialized formulations promote noticeable nail extension and improvement.<\/p>\n
If you’re short on time, here’s a quick answer to your question: Nail growth serums can indeed help stimulate modest gains in nail length and thickness by providing keratin, biotin, collagen, and other compounds<\/b>.<\/p>\n
Gains are relatively subtle and results take time, but many users report some improvements in nail growth rate and appearance with consistent use.<\/p>\n
In this 3000 word guide, we’ll cover the science behind nail growth and the common ingredients in serums. We’ll review research on the most promising compounds like peptides and collagen. We also consider factors like nail health issues, age, diet, and more that can influence the impact of serums.<\/p>\n
And we’ll evaluate 5 top-rated nail growth serum products on the market.<\/p>\n
Nails start their life under the skin at the nail root, which has cells that multiply to make the nail cells. The nail cells pile up in layers, creating the nail plate. The nail plate then grows outward toward the fingertip from the cuticle area.<\/p>\n
As new cells pile up, the older nail cells get pushed out toward the end of the finger.<\/p>\n
On average, nails grow at a rate of 0.1 mm per day. Toenails tend to grow slower than fingernails. It takes about 6 months for fingernails and 12-18 months for toenails to completely regrow from the cuticle area to the end of the digit.<\/p>\n
The key parts involved in natural nail growth include the nail matrix (root), nail bed, cuticle, lunula, nail plate, and hyponychium. The matrix cells undergo keratinization to become hard nail plate cells. The nail bed under the nail plate provides nutrients and structure to anchor the growing nail.<\/p>\n
Genetics play a major role in determining the thickness, growth speed, and health of one’s nails. However, some controllable factors can influence nail growth too:<\/p>\n
