What is a good nail hardener to use?

 Choosing the "best" nail hardener depends on your specific needs and concerns. Here are some factors to consider:

Your Nail Concerns:

• Broken/chipped nails: Look for hardeners with protein, calcium, or keratin to strengthen and nourish nails. OPI Nail Envy or Sally Hansen Hard As Nails Xtreme Wear are good options.
• Peeling nails: Try hardeners with biotin or hyaluronic acid to promote moisture and flexibility. NailTek Strengthener II or Essie Strong Start are popular choices.
• Thin nails: Choose hardeners with conditioning ingredients like jojoba oil or argan oil to moisturize and protect. Revitanail Nail Strengthener or CND SolarOil are highly rated.

Formula:

• Liquid: Most common, easy to apply, dries quickly.
• Pen: Targeted application, good for weak spots.
• Cream: Hydrating, ideal for dry nails, takes longer to dry.

Ingredients:

• Formaldehyde: Effective but harsh, can cause irritation. Look for formaldehyde-free options if sensitive.
• Toluene: Another effective but controversial ingredient, choose alternatives if worried.
• Vegan and cruelty-free: Check if these are important to you.

Here are some top-rated options based on different needs:

• Overall: Duri Rejuvacote 1 (protein & calcium)
• Budget: Nail-Aid Keratin 3 Day Growth Treatment
• Peeling nails: Olive and June Nail Strengthener
• Thin nails: Barielle Nail Strengthener Cream

Tips for using nail hardener:

• Apply in thin layers, 2-3 times a week.
• Wear gloves for cleaning or using harsh chemicals.
• Take breaks with regular nail polish (not just hardener) to allow nails to breathe.
• Consider a nail care routine with moisturizer and cuticle oil.
