Ever feel like your hair just won’t behave no matter how many products you use? You could be using all the shampoos, masks, and oils—but if you don’t understand your hair’s porosity, you might be working against it!

Hair porosity is the key to knowing how well your hair absorbs and holds moisture. And guess what? It can make or break your hair routine! So, let’s dive into the world of porosity and learn how to treat our hair the right way—Luciano Cimmarrusti style, of course!

What Is Hair Porosity?

Hair porosity is all about your hair’s ability to soak up and retain moisture. Think of your hair like a sponge—some sponges absorb water instantly, while others take their time. Your hair does the same with products!

Porosity is determined by the condition of your hair’s cuticle layer—the tiny outer layer of your strands. Depending on how open or closed these cuticles are, your hair falls into one of three porosity levels:

1. Low Porosity: The Resistant Type

If your hair takes forever to absorb water and products seem to sit on top rather than sink in, you have low porosity hair. The cuticles are tightly closed, making it hard for moisture to enter—but once it does, it stays put!

How to care for low porosity hair:
✔️ Use lightweight, water-based products to avoid buildup.
✔️ Apply heat (like a warm towel or steamer) when deep conditioning to help products penetrate.
✔️ Avoid heavy butters and oils—they’ll just sit on your strands.

2. Medium Porosity: The Balanced Queen

If your hair absorbs moisture well but doesn’t dry out too fast, you’ve hit the porosity jackpot! Medium porosity hair has a slightly open cuticle, which allows it to hold moisture beautifully.

How to care for medium porosity hair:
✔️ Use a mix of moisture and protein treatments to maintain balance.
✔️ Don’t overdo heat styling—too much can raise your porosity over time.
✔️ Enjoy your hair’s natural versatility!

3. High Porosity: The Thirsty One

Does your hair get wet super fast but dry out just as quickly? That’s a sign of high porosity hair. Your cuticles are too open—often due to damage from heat, coloring, or over-manipulation—so moisture enters easily but escapes just as fast.

How to care for high porosity hair:
✔️ Use moisturizers.
✔️ Protein treatments are your best friend—they help repair and strengthen the cuticle.
✔️ Avoid over-washing, as it strips moisture even more.

How to Test Your Hair Porosity

Wondering which porosity type you have? Try this quick and easy water test:

1️⃣ Take a clean strand of hair (shed naturally, don’t pull!).
2️⃣ Drop it into a glass of water.
3️⃣ Watch what happens!

  • If it floats for a long time, you have low porosity.
  • If it slowly sinks, you have medium porosity.
  • If it sinks immediately, you have high porosity.

Simple, right?

Final Thoughts: Work With Your Hair, Not Against It!

Understanding your hair’s porosity is like unlocking a secret weapon in your haircare routine. Instead of guessing what products work, now you know exactly what your hair needs!

Luciano Cimmarrusti always says that healthy hair is beautiful hair, and knowing your porosity is the first step to keeping your locks looking their best. So, embrace your porosity, pamper your strands, and watch your hair thrive!
