Stronger Strands Start Here: Why Porosity Matters
Tired of using “the best” products but still dealing with dry, frizzy hair? Without understanding porosity, you’re just guessing. Here’s how to identify what your hair needs, so you can finally give your hair what it’s really asking for. Porosity is the reason two people can use the exact same products and get completely different results.
It influences:
- How quickly your hair absorbs water or product
- How long it stays moisturized
- How well it holds protein treatments or keratin services
While some people are born with naturally low, medium, or high porosity hair, it can also change over time based on how you treat your hair.
Some common porosity changers include:
-
Heat styling (blow drying, flat ironing)
-
Chemical treatments (color, bleach, relaxers)
- Environmental damage (sun, hard water, pollution)
Here’s a simple way to find out your hair’s porosity using just a glass of water:
-
Start with a clean strand of hair-no product, oils, or conditioner on it.
-
Fill a clear glass or cup with room temperature water.
-
Drop the strand into the water and wait 2–4 minutes.
If your hair :
-
Floats at the top and takes a long time to sink, you likely have low porosity. Your cuticles are tightly packed, so water has a hard time getting in.
-
Sinks slowly, hovering somewhere in the middle, you probably have medium or normal porosity. This is the sweet spot-your hair absorbs and retains moisture well.
- Sinks quickly to the bottom, that’s a sign of high porosity. Your cuticles are more open, which means moisture rushes in but also escapes quickly. This is often due to damage from heat or chemical treatments.
Every porosity level has its own unique needs but the good news is, you don’t have to figure it out alone. By identifying your porosity and pairing it with the right Lasio products and treatments, you can stop guessing and start giving your hair exactly what it needs-whether that’s deep hydration, protein rebuilding, or a little bit of both.
Low porosity hair benefits from lightweight, water-based formulas and gentle heat to open the cuticle. Start your routine with the sulfate-free Replenishing Shampoo, which effectively lifts away buildup while maintaining the hair’s natural moisture balance. To build on that clean, hydrated base, follow with the Replenishing Conditioner, designed to soften and moisturize without adding weight- ideal for low porosity strands.
For those with medium porosity hair maintaining balance is key. This hair has a healthy cuticle that allows moisture in and keeps it there, but over time, heat, coloring, and environmental stress can weaken it. To keep your hair strong and elastic, a consistent routine alternating hydration and protein treatments works best. Lasio’s Deep Cacao Moisture Mask offers deep hydration without heaviness, the Keratin Tropic Treatment smooths without disrupting natural texture.
When it comes to high porosity hair, reparative treatments are essential to restore internal strength and seal the cuticle for lasting moisture. Key ingredients like collagen, biotin, keratin, and hyaluronic acid work together to rebuild structure and improve elasticity. Lasio’s salon-exclusive Follicle Filler targets the hair’s inner cortex to rebuild bonds, followed by the Deep Cacao Moisture Mask to replenish moisture and smooth the cuticle. To maintain these results, the gentle, sulfate-free Replenishing Shampoo cleanses without stripping hydration.
And remember, treatments like Follicle Filler or Lasio Keratins aren’t products you buy off a shelf, they’re professional-grade services delivered by Lasio-certified stylists who understand how to customize them for your hair type.
