Hair Porosity Explained: Why Your Hair Absorbs Nothing

If your hair: feels dry even after conditioning gets frizzy immediately absorbs oil too fast—or not at all stays wet forever never seems hydrated …the problem may not be your products. It may be your hair porosity. In the Grit & Glow Lab, we see porosity as one of the most overlooked reasons people struggle with dryness, breakage, buildup, and “unmanageable” hair. Because healthy hair isn’t only about what you apply. It’s about whether your strands can actually absorb and retain moisture properly. This guide explains what hair porosity means, how to identify your porosity type, and how to build a smarter hair routine that actually works for your hair structure. What Is Hair Porosity? Hair porosity refers to your hair’s ability to absorb and retain moisture. Your hair strand is protected by a cuticle layer made of overlapping scales. When the cuticle is: tightly closed → moisture struggles to enter balanced → hydration stays stable raised or damaged → moisture escapes too quickly ๐Ÿ‘‰...

The Sweat Equity: How to Achieve the High-Impact "Active Glow"

 

There is a specific kind of radiance that only comes from the "Grit." It’s that post-workout, high-performance sheen that looks expensive because it’s rooted in health.

In the Grit & Glow world, we don’t do complicated 12-step routines that slide off the second you break a sweat. We focus on high-performance products that work as hard as you do. Here is how to get the model-off-duty glow that lasts from the gym to the office.

๐Ÿ› ️ The Foundation: Internal Grit

You can’t polish dull skin into a glow. Real radiance starts with circulation and hydration.

  • The Sweat Benefit: Exercise increases blood flow, carrying oxygen and nutrients to working cells throughout the body, including the skin.

  • Hydration Strategy: If you aren't drinking half your body weight in ounces of water, your "glow" is just surface oil.

✨ The Routine: High-Performance Products

To get the look in the photo, you need a routine that emphasizes texture and luminosity.

1. The Deep Reset (Exfoliation)

You can't glow through a layer of dead skin. Use a chemical exfoliant (AHA) twice a week to resurface the "grit" and reveal the fresh cells beneath.

  • Top Pick: Glycolic Acid (like the The Ordinary Glycolic Acid 7% Toning Solution).

2. The Vitamin C Shield

For that bright, even-toned look, Vitamin C is non-negotiable. It fights oxidative stress from your environment and gives an immediate brightening effect.

  • Top Pick: CeraVe Vitamin C Serum (Contains 10% pure vitamin C plus ceramides to keep the barrier strong).

3. The "Glass" Hydrator

The model in the image has skin that looks bouncy. This comes from Glycerin and Hyaluronic Acid. Apply these to damp skin to lock in moisture.

  • Top Pick: La Roche-Posay Hyalu B5 Serum.

The Grit & Glow Rule: > Never workout in makeup. When you sweat, your pores open up. If they’re clogged with foundation, you’re trading a temporary glow for a week of breakouts. Wash, workout, then apply your glow.
