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‘‰...

From Shedding to Shredding: Why Your Hair Growth Strategy Needs a Two-Pronged Attack

 

Let’s be honest: we’ve all had those "drain-clogging" moments. You’re in the shower, you run your fingers through your hair, and a small family of strands decides to move out. It’s frustrating, it’s a bit scary, and it usually sends us spiraling into a late-night search for the "magic pill" that will turn our mane into a Pinterest-worthy masterpiece.

Welcome back to Grit and Glow. Here, we believe that the "glow" is the result of the "grit"—the consistent, smart habits that actually move the needle. When it comes to hair that looks fuller, thicker, and genuinely healthy, the biggest mistake people make is only fighting half the battle. If you’re only treating your hair from the outside (with masks) or only from the inside (with vitamins), you’re leaving results on the table.

To truly target shedding and support new growth, you need a system. Here is how to master the dual-action approach.


Step 1: The Internal Grit (The Nutrients)

Your hair is essentially a history book of your nutrition from three months ago. Because hair is a "non-essential" tissue, your body is the ultimate minimalist; if you’re stressed or lacking vitamins, your body sends those nutrients to your heart and lungs first, leaving your follicles to starve.

To stop the shedding, you have to feed the root. You’re looking for a specific blend of Biotin, Zinc, and Amino Acids. These aren't just buzzwords; they are the literal building blocks of the keratin protein. By taking a high-quality daily supplement, you are ensuring that as new hair is born, it’s coming out stronger and more resilient than the generation before it. It’s about building a foundation that doesn't snap the second you pick up a curling iron.

Step 2: The External Glow (The Scalp Environment)

If the vitamins are the seeds, your scalp is the soil. You can have the best seeds in the world, but if the soil is dry, congested, or lacks circulation, nothing is going to grow. This is where a targeted Scalp Serum becomes your best friend.

Modern serums are designed to do more than just "moisturize." They are formulated to:

  • Nourish the Follicle: Delivering concentrated ingredients directly to the source of growth.

  • Target Shedding: Helping to keep the hair in the "growth phase" for longer so it doesn't fall out prematurely.

  • Create Visual Volume: Many serums include lightweight ingredients that lift the hair at the root, giving you that "thicker-looking" finish immediately while the long-term growth work happens underneath.


Why the "2-Piece" Strategy Wins

The magic happens when these two forces meet. While the vitamins are working on the long game—strengthening the hair that hasn't even emerged yet—the serum is protecting and revitalizing the hair you currently have. It’s a 24/7 cycle of protection and promotion.

The 90-Day Rule

Here is the "grit" part: your hair doesn't care about your Friday night plans. It operates on its own timeline. Because of the natural hair growth cycle, you won't see a transformation overnight. You need at least 90 days of consistency to see the shedding slow down and the new growth fill in those gaps.
