This sums up the list of popular nail growth serums available online. Here is a quick explanation of how these serums work.

Do Nail Growth Serums Work?

Absolutely! Like every part of our body, the nails too need nourishment and care. They might require certain nutrients like vitamins A, E, B, and C, biotin, and plant oils that boost their growth and repair. Nail growth serums contain these ingredients.

With consistent use, nail growth serums

  •  Nourish the nail bed
  •  Soften the cuticles
  •  Preserve the integrity of the nail enamel
  •  Harden brittle nails
  •  Support faster nail growth
  •  Promote damage and breakage resistance

Nail growth serums are game changers, and it is a good idea to invest in them. But how to pick the best from the rest? Here are some useful tips.

How To Choose The Best Nail Growth Serum

Consider the following factors while shopping for a nail growth serum:

  •  Ingredients: It is not enough if a nail growth serum contains oils and glycerin. The actual growth is brought about by vitamins, proteins, and certain growth factors. Look for ingredients like biotin, phytantriol, keratin, and vitamins A, C, E, and B. Vitamins can also be listed as retinyl palmitate, ascorbic acid, tocopherol, and panthenol, respectively.
  •  Ease Of Application: A good nail serum doesn’t need to have an elaborate application process. You don’t necessarily have to visit a manicurist. It should be a user-friendly formula that dries or gets absorbed quickly. Pick a serum that comes with a contoured applicator or brush and is easy to wear.
  •  No Toxicity: A nail growth serum cannot have toxic substances. Stay away from products that contain parabens, sulfates, petrolatum, dyes, etc.

Whether you desire long, sturdy nails or like to keep them in regular shape and health, it is good to have a nail growth serum in your nail care kit. The ones listed here can be used by women, men, and children too. If you are done with bitten and brittle nails, dried cuticles, and bleeding hangnails, these serums are your new BFFs. Go through the options and useful tips and get home your favorite nail growth serum right away!
